      • Understand the basic properties and different environments of Solid Edge.

      • Know the system requirements for installing Solid Edge ST7.

      • Get familiar with important terms and definitions.

      • Understand the user interface.

      • Save the Solid Edge designs automatically after regular intervals.

      • Modify the color scheme.

      Introduction to Solid Edge ST7

      Welcome to the world of Solid Edge ST7, a product of SIEMENS. If you are a new user of this software, you will join hands with thousands of users of this high-end CAD tool worldwide. This software helps the users improve their design skills. Also, in this software, the user interaction has been taken to a new level, thus making Solid Edge one of the easiest and popular mechanical CAD products.

      Solid Edge is a powerful software that is used to create complex designs with great ease. The design intent of any three-dimensional (3D) model or an assembly is defined by its specification and use. You can use the powerful tools of Solid Edge to capture the design intent of any complex model by incorporating intelligence into the design. With Synchronous Technology, Solid Edge redefines the rules of 3D modeling. It combines the speed and flexibility of modeling with precise control of dimension-driven design, thereby generating tremendous productivity gains over traditional methods.

      In Solid Edge, the synchronous and traditional (now called Ordered) modeling environments are combined into a single modeling environment. This means, you do not need two separate environments to work with synchronous and traditional modeling technologies. The most interesting feature is that you can switch between the Synchronous and Ordered environments and can convert a particular Ordered feature into a Synchronous feature.

      To make the design process simple and efficient, this software package divides the steps of designing into different environments. This means each step of the design process is completed in a different environment. Generally, a design process involves the following steps:

      • Sketching by using the basic sketch entities and converting them into features or parts. These parts can be sheet metal parts, surface parts, or solid parts.

      • Assembling different parts and analyzing them.

      • Generating drawing views of the parts and the assembly.

      All these steps are performed in different environments of Solid Edge, namely Synchronous Part/Ordered Part, Assembly, Synchronous Sheet Metal/ Ordered Sheet Metal, Weldment, and Draft.

      Solid Edge provides Software Development Kit (SDK) that helps you customize Solid Edge according to your requirement. Solid Edge also provides assistance, tutorials, and technical support to the users. The tutorials can be browsed from the welcome screen. You can view as well as work on the models simultaneously. Solid Edge helps you find commands quickly by using the Command Finder. The enhanced tooltip in Solid Edge provides you complete information of a tool such as its name and description as well as the shortcut keys to invoke the tool.

      Solid Edge supports data migration from various CAD packages such as IDEAS, AutoCAD, Mechanical Desktop, Pro/E, Inventor, CATIA, and NX. As a result, you can convert all the files and documents created in these software into a Solid Edge document. You can also view or change the settings of a file while importing it. Solid Edge allows you to evolve a 3D model from a 2D drawing created in the Draft environment of Solid Edge or imported from any other software.

      Solid Edge ST7 is a synchronous, parametric, and feature-based solid modeling software. The bidirectional associative nature of this solid modeling software makes the design process very simple and less time-consuming. The synchronous, parametric, feature-based, and bidirectional properties of this software are explained next.

      Synchronous Technology

      The Synchronous Technology and the new commands and workflow concepts of Solid Edge has made modeling in this software much easier, faster, and accurate than in any other parametric modeling software package. This is because the synchronous technology enables you to create sketches as well as to develop features in the same environment. Note that the features created in the Synchronous environment do not depend on the order of their creation. Therefore, the editing of the model becomes a lot easier. This state-of-the-art technology makes Solid Edge ST7 a completely feature-based 2D/3D CAD software package.

      Parametric Nature

      Parametric nature of a solid modeling package means that the sketch is driven by dimensions, or in other words, the geometry of a model is controlled by its dimensions. For example, to model a rectangular plate of 100X80 units, you can draw a rectangle of any dimension and then modify its dimensions to the required dimensions of the plate. You will notice that the dimensions drive the geometry of the sketch.

      Therefore, using this parametric property, any modification in the design of a product can be accomplished at any stage of the product development. This makes the design flexible.

      Feature-based Modeling

      A feature is defined as the smallest building block of a model. Any solid model created in Solid Edge is an integration of a number of features. Each feature can be edited individually to make any change in the solid model. As a result, the feature-based property provides greater flexibility to the created parts.

      The advantage of dividing a model into a number of features is that it becomes easy to modify the model by modifying the features individually. For example, Figure 1-1 shows a model with four simple holes near the corners of the plate.

      C01SC01.PCX

      Figure 1-1 Model with simple holes

      Now, consider a case where you need to change all outer holes to counterbore holes. In a non-feature based modeling package, you need to delete all the holes and then create the counterbore holes. However, in Solid Edge, you can modify some parameters of the holes in the same part and convert the simple holes into counterbore holes, see Figure 1-2.

      C01SC02.PCX

      Figure 1-2 Model with counterbore holes

      Bidirectional Associativity

      The bidirectional associativity of a software package is defined as its ability to ensure that any modification made in a particular model in one environment is also reflected in the same model in the other environments. For example, if you make any changes in a model in the Part environment, the changes will reflect in the same model in the Assembly environment and vice-versa.

      Figure 1-3 shows the top view and the sectioned front view of the part shown in Figure 1-1.

      C0ISC002.PCX

      Figure 1-3 Drawing views of the model before modification

      These drawing views are generated in the Draft environment. The views show that the part consists of a simple hole at the center and four simple holes near the corners. Now, when the model is modified in the Part environment, the modifications are automatically reflected in the Draft environment, refer to Figure 1-4. This figure shows that the four simple holes are converted into counterbore holes. This implies that the Part environment and the Draft environment of Solid Edge are bidirectionally associative.

      C0ISC003%20-%20Copy.PCX

      Figure 1-4 Drawing views of the model after modification

      Note

      The modifications done on the views in the Draft environment do not reflect in other environments.

      Consider the assembly shown in Figure 1-5. The piston is connected to the connecting rod through a pin. It is clear from the assembly that the diameter of the hole is more than what is required. In an ideal case, the diameter of the hole on the piston should be equal to the diameter of the pin.

      C01SC03.PCX

      Figure 1-5 Piston, connecting rod, and pin assembly

      Now, when you open the piston in the Part environment and modify the diameter of the hole on it, the same modification is also reflected in the Assembly environment, as shown in Figure 1-6. This is due to the bidirectional associative nature of Solid Edge.

      Similarly, if the modification is made in the Assembly environment, the piston, when opened in the Part environment, is also modified automatically. This shows that all environments of Solid Edge are associative by nature.

      Figure 1-6 Assembly after modifying the diameter of the hole on the piston

      Solid Edge environments

      To reduce the complexity of a design, this software package provides you with various design environments. You can capture the design intent easily by individually incorporating the intelligence of each design environment into the design. The design environments available in Solid Edge are discussed next.

      Part Environment

      This environment of Solid Edge ST7 is used to create solid as well as surface models. The Part environment consists of two environments namely Synchronous Part and Ordered Part. You can switch between these environments and create a model which consists of both synchronous and ordered features. To invoke this environment, start Solid Edge ST7 by double-clicking on the shortcut icon of Solid Edge ST7 on the desktop of your computer. After Solid Edge ST7 starts, a welcome screen is displayed. From this screen, choose the ISO Metric Part option from the Create area; the part environment gets started with the ISO units. By default, the Synchronous Part environment is invoked. However, you can switch to the Ordered Part environment by choosing the Ordered radio button from the Model group of the Tools tab.

      Synchronous Part

      Solid Edge ST7 with the Synchronous Technology makes it a complete feature-based 2D/3D CAD system. This technology combines the speed and flexibility of direct modeling with precise control of dimension-driven design. In this environment, there is no separate environment to draw sketches; rather the sketching tools are available in the Synchronous Part environment itself. It includes direct model creation and modification through precision sketching, region selection, face selection, and handle selection.

      Ordered Part

      The Ordered Part environment of Solid Edge ST7 is used to create parametric and feature-based solids as well as surface models. You can draw sketches of models or features by invoking the sketching environment. Once the sketch is drawn, you can convert it into a solid model using simple but highly effective modeling tools. One of the major advantages of using Solid Edge is the availability of command bar. The command bar is displayed in the drawing window. In this environment, you can create a feature step by step by using the command bar. You can also use the command bar to easily go one or more steps backward to modify a parameter. You can also convert the features created in this environment to the synchronous features for editing them directly. The models created in the part environment can also be used in the other environments of Solid Edge to complete the model’s life cycle, also known as the Product Life Cycle.

      Assembly Environment

      This environment of Solid Edge is used to create an assembly by assembling the components that were created in the Synchronous/Ordered Part environment. Both the synchronous and ordered tools are combined in this environment. This environment supports animation, rendering, piping, and wiring. Other visualization and presentation tools are also available in this environment. In addition to that, you can apply a relation between the faces of two different synchronous components in an assembly. For example, you can make the selected face of a component tangent with the target face of another component.

      Draft Environment

      This environment is used for the documentation of the parts or the assemblies in the form of drawing views. The drawing views can be generated or created. All the dimensions added to the component in the part environment during its creation can be displayed in the drawing views in this environment.

      Sheet Metal Environment

      This environment is used to create sheet metal components. If you are familiar with the part environment, then modeling in this environment becomes easy. This is because in addition to the sheet metal modeling tools, this environment works in a way similar to the part environment. To invoke this environment, start Solid Edge ST7; a welcome screen will be displayed. Choose the ISO Metric Sheet Metal option from the Create area in the welcome screen; the Sheet Metal environment gets started with the ISO units. By default, the Synchronous Sheet Metal environment is invoked. However, you can switch to the Ordered Sheet Metal environment by choosing the Ordered radio button from the Tools tab.

      Synchronous Sheet Metal

      The Synchronous Sheet Metal environment is used to create and edit sheet metal components in a history-free approach. The procedure of selection of faces introduced in this environment allows you to model sheet metals directly. You can create a dimension-driven design of the sheet metal components in Solid Edge.

      Ordered Sheet Metal

      The Ordered Sheet Metal environment is used to create parametric and feature-based sheet metal components.

      Weldment Environment

      This environment enables you to insert components from the Part or the Assembly environment and apply weld beads to the parts or the assembly. This environment is associative with the Part and Assembly environments.

      Important terms and definitions

      Some important terms that are used in this textbook are discussed next.

      Relationships

      Relationships are the logical operations that are performed on a selected geometry to make it more accurate by defining its position and size with respect to the other geometry. There are two types of relationships available in Solid Edge and they are discussed next.

      Geometry Relationships

      These logical operations are performed on the basic sketched entities to relate them to the standard properties such as collinearity, concentricity, perpendicularity, and so on. Although Solid Edge automatically applies these relationships to the sketched entities at the time of drawing, you can also apply them manually. You can apply different types of geometry relationships, which are discussed next.

      Connect

      This relationship connects a point to another point or entity.

      Concentric

      This relationship forces two selected curves to share the same center point. The curves that can be made concentric are circles, arcs, and ellipses.

      Horizontal/Vertical

      This relationship forces the selected line segment or two points to become horizontal or vertical.

      Collinear

      This relationship forces two line segments to lie on the same line.

      Parallel

      This relationship is used to make two line segments parallel.

      Perpendicular

      This relationship makes a line segment perpendicular to another line segment or series of line segments.

      Lock

      This relationship is used to fix an element or a dimension such that it cannot be modified.

      Tangent

      This relationship is used to make the selected line segment or curve tangent to the selected line or curve.

      Equal

      This relationship forces the selected line segments to be of equal length. It also forces two curves to be of equal radius.

      Symmetric

      This relationship is used to force the selected sketched entities to become symmetrical about a sketched line segment, which may or may not be a center line.

      Rigid Set

      This relationship is used to group the selected sketched entities into a rigid set so that they behave as a single unit.

      Feature Relationships (Only in Synchronous Part Environment)

      The feature relationships are the relationships that are applied on a selected face to make it geometrically related to the target face. These relationships are used to modify the parts created in the Synchronous Part environment. These relationships are available in the Face Relate group of the Home tab in the ribbon in the Synchronous Part environment. The following types of feature relationships can be applied between faces:

      Concentric

      This relationship makes the selected faces concentric with the target face.

      Coplanar

      This relationship makes the selected faces coplanar with the target face.

      Parallel

      This relationship enables you to make the selected faces parallel to the target face.

      Perpendicular

      This relationship helps you to make the selected faces perpendicular to the target face.

      Tangent

      This relationship makes the selected faces tangent with the target face.

      Rigid

      This relationship is used to make all the faces in the selection set rigid with respect to each other. This means, if either of the face is moved or rotated, then all the related faces will also move or rotate, thereby maintaining the distance and orientation between them.

      Ground

      This relationship grounds or constrains the selected face in the model space. As a result, the grounded faces can be neither moved nor rotated.

      Symmetry

      This relationship makes a selected face symmetric to a target face about a symmetry

      plane.

      Equal

      This relationship makes the radius of a selected cylindrical face equal to the radius of a target cylindrical face.

      Coplanar Axis

      This relationship is used to make the axes of multiple cylindrical faces coplanar.

      Offset

      This relationship is used to offset a face with respect to another face.

      Horizontal/Vertical

      This relationship forces a horizontal/vertical face or keypoint to align with another horizontal/vertical face or keypoint.

      Assembly Relationships

      The assembly relationships are the logical operations that are performed on the components to assemble them at their respective working positions in an assembly. These relationships are applied to reduce the degrees of freedom of the components.

      Flash Fit

      This relationship minimizes the efforts of applying various relationships like: Mate, Planer Align, and so on by automatically positioning the component wherever required.

      Mate

      This relationship is used to make the selected faces of different components coplanar. You can also specify some offset distance between the selected faces.

      Planar Align

      This relationship enables you to align a planar face with the other planar face.

      Axial Align

      This relationship enables you to make a cylindrical surface coaxial with the other cylindrical surface.

      Insert

      This relationship is used to mate the faces of two components that are axially symmetric and also to make their axes coaxial.

      Connect

      This relationship enables you to connect two keypoints, line, or a face on two different parts.

      Angle

      This relationship is used to place the selected faces of different components at some angle with respect to each other.

      Tangent

      This relationship is used to make the selected face of a component tangent to the cylindrical, circular, or conical faces of the other component.

      Cam

      This relationship applies the cam-follower relationship between a closed loop of tangent face and the follower face.

      Parallel

      The Parallel relationship is used to force two edges, axes, or an edge and an axis parallel to each other.

      Gear

      The Gear relationship allows you to apply rotation-rotation, rotation-linear, or a linear-linear relationship between two components.

      Center-Plane

      This relationship is used to align a component at an equal distance between the two faces of other component, planes, or key points.

      Path

      This relationship is used to apply a mate such that the part moves along a path.

      Match Coordinate Systems

      This relationship is used to match the coordinate system of one component/part with the coordinate system of another component/part.

      Rigid Set

      This relationship is used between two or more components to fix them such that they become rigid with respect to each other.

      Ground

      This relationship is used to fix a component at a specified location and orientation. Solid Edge automatically applies a ground relationship to the first part placed in an assembly.

      Entity

      An element of a geometry is called an entity. An entity can be an arc, line, circle, point, and so on.

      Concept of a Profile and a Sketch

      In Solid Edge, there are two methods of drawing a sketch. The first method is to draw a sketch in the sketching environment by invoking the Sketch tool from the Home tab. The second method is to invoke a feature creation tool such as Extrude, Revolve, and so on and then draw the sketch for the feature. The sketch drawn using the first method is called a Sketch and the sketch drawn using the second method is called a Profile. You will learn more about this in the later chapters of this book.

      Note

      1. If you are working in the Synchronous Part environment, you can not invoke a feature creation tool such as Extrude, Revolve, and so on if you do not have a sketch.

      2. In the Synchronous Part environment, you can select the sketching tools without switching to another environment.

      Intent Zone

      The intent zone is defined by a circular area that is divided into four quadrants. It is used while drawing an arc or a circle from a line, or vice-versa. The quadrants define whether the element is perpendicular, tangent or at some other orientation from the other element. This zone enables you to draw or modify various elements of a geometry within the same tool. For example, while drawing a line tangent to an arc, you can draw a tangent arc or a perpendicular arc by moving the cursor in the intent zone. The movement of the cursor in the intent zone determines the creation of a tangent or a perpendicular arc. The intent zone while drawing a tangent arc and a three point arc is shown in Figure 1-7 and 1-8, respectively.

      Drawing Sketches for Solid Models

      Learning Objectives

      After completing this chapter, you will be able to:

      • Understand various sketching tools.

      • Understand various drawing display tools.

      • Use various selection methods.

      • Delete sketched entities.

      sketching in the part Environment

      Most solid models consist of closed sketches, placed features, and reference features. A closed sketch is a combination of a number of two-dimensional (2D) entities such as lines, arcs, circles, and so on. The features based on a closed sketch are created by using these entities. Generally, a closed sketch-based feature is the base feature or the first feature. For example, the solid model shown in Figure 2-1 is created by using the sketch shown in Figure 2-2.

      C01SC01.PCX

      Figure 2-1 Solid model

      43114.jpg

      Figure 2-2 Profile of the solid model

      In most designs, you first need to draw a sketch, add relationships and dimensions to it, and then convert it into a base feature. After doing so, you can create advanced features like cuts, holes, ribs, shells, rounds, chamfers, and so on, on the base feature.

      There are two methods to start a new document in the Part environment. The first one is to use the welcome screen to start a new file in the Part environment. The second one is to start a new part document by using the New dialog box. These methods are discussed next.

      Starting a New Document in the Part Environment

      To start the Part environment, first you need to start Solid Edge. To do so, double-click on the shortcut icon of Solid Edge ST7 on the desktop of your computer.

      Figure 2-6 New document in the Part environment

      Note

      1. In the Synchronous Part environment, the basic drawing tools are available in the Home tab as well as in the Sketching tab.

      2. You can start Solid Edge directly in a particular template file. To do so, choose the Application Button from the top left of the application window; a flyout will be displayed Choose the Solid Edge Options button from the flyout; the Solid Edge Options dialog box will be displayed. In this dialog box, choose Helpers and then select the required template from the drop-down list next to the Start using this template radio button.

      Transition between part environments

      In Solid Edge ST7, there are two modeling environments coexisting in the same file, the Synchronous Part environment and Ordered Part environment. The Synchronous Part environment is used to create synchronous features whereas the Ordered Part environment is used to create ordered features. Note that the Ordered Part environment was earlier referred as the traditional environment. By default, a new Solid Edge document starts in the Synchronous environment. In Solid Edge ST7, you can work in both the environments in the same file. You can switch between the Synchronous and Ordered environments at any time during the modeling process. To do so, right-click in the graphics window; a shortcut menu will be displayed. Choose the Transition to Ordered or Transition to Synchronous option from the shortcut menu to switch from Synchronous Part environment to Ordered Part or vice-versa. You can also switch between environments by choosing the required modeling environment from the Model group of the Tools tab.

      Starting a sketch in the part environment

      In the Synchronous Part environment, a triad representing the base coordinate system is displayed at the center of the graphics area. You can draw sketches on any of the principal planes of the base coordinate system. To draw a sketch, invoke a sketching tool from the Draw group; two green lines of infinite length get attached to the cursor. Move the cursor toward the axis of the base coordinate system; you will notice that the respective plane gets highlighted and a Lock symbol is displayed on it.

      You can also select the required plane by using the QuickPick listbox. To do so, move the cursor toward the base coordinate system and wait for a while; a mouse symbol will be displayed near the cursor. Next, right-click; the QuickPick list box will be displayed with a list of alternate planes that can be selected for drawing the sketches, as shown in Figure 2-7. Now, you can select the required plane for sketching.

      C01SCST7010.pcx

      Figure 2-7 The QuickPick list box with the list of planes

      Note

      In Solid Edge, the base reference planes are hidden by default. You can display the base reference planes individually or in group by selecting the Base Reference Planes check box in the PathFinder.

      Locking and Unlocking Sketching Plane

      If you want all input commands to be in the same plane, you can lock that sketch plane. It implies that all the sketches and their dimensions are drawn on the same plane. To lock the plane, click on the Lock symbol that will be displayed on selecting any principal plane or face of the solid. On doing so, the sketch plane will get locked and the Lock symbol will be displayed at the upper right corner of the drawing window. Now, you can draw sketches, add dimensions to them, and so on. In this case, you will notice that the sketches along with their relationships and dimensions are on the same plane, and will be added as a single sketched entity under the Sketches node of the PathFinder. The plane will remain locked until you unlock it by clicking on the Lock symbol again. If you want to draw a sketch in some other plane, first you need to unlock the plane and then invoke a sketching tool again. Next, select the required plane.

      However, to draw a sketch in the Ordered Part environment, switch to the Ordered Part environment and choose the Sketch tool from the Sketch group of the Home tab; you will be prompted to click on a planar face or a reference plane. Select a reference plane, the selected plane will be oriented parallel to the screen and the sketching environment will be invoked. Now, you can draw the sketch using various sketching tools that are discussed next.

      Sketching Tools

      In the Synchronous Part environment, the sketching tools are available in the ribbon of the synchronous part environment. But in the Ordered Part environment, you first need to invoke the sketch environment to use a sketching tool. All the tools required to create a profile or a sketch in Solid Edge are available in the Draw group and are discussed next.

      Drawing Lines

      Ribbon: Home > Draw > Line

      In any design, lines are the most widely used sketched entities. In Solid Edge, the Line tool is used to draw straight lines as well as to draw the tangent or normal arcs originating from the endpoint of a selected line. The properties of the line are displayed in the command bar, as shown in Figure 2-8.

      C01SC12.PCX

      Figure 2-8 The Line command bar

      Drawing Straight Lines

      To draw a straight line, choose the Line tool; you will be prompted to select the first point for the line. Specify the point (click) in the drawing window by pressing the left mouse button; a rubber-band line will be attached to the cursor. Also, you will be prompted to select the second point for the line. Note that on moving the cursor in the drawing window, the length and angle of the line also gets modified accordingly in the Line command bar. Next, specify the endpoint of the line in the drawing window by pressing the left mouse button. Alternatively, you can draw a line by specifying its length and angle in the Line command bar.

      While drawing a line, you will notice that some symbols are displayed on the right of the cursor. For example, after specifying the start point of the line, if you move the cursor in the horizontal direction, a symbol similar to a horizontal line will be displayed. This symbol is called the relationship handle and it indicates the relationship that will be applied to the entity being drawn. In the above-mentioned case, the horizontal relationship handle is displayed on the right of the cursor. This relationship will ensure that the line you draw is horizontal. These relationships are automatically applied to the profile while drawing a line.

      Note

      Relationships are also applied between the sketched entities and the reference planes. You will learn more about relationships in the later chapters.

      The process of drawing lines does not end after defining the first line. You will notice that as soon as you define the endpoint of the first line, another rubber-band line starts. The start point of this line becomes the endpoint of the first line and the endpoint of the new line is attached to the cursor.

      The process of drawing consecutive lines continues until you right-click to terminate it. However, even after right-clicking, the Line tool will remain active and you will be prompted to specify the first point of the line. You can terminate the Line tool by choosing the Select tool from the Select group or by pressing the ESC key. Figures 2-9 and 2-10 show the continuous lines being drawn.

      While drawing lines, you will notice that if the cursor is horizontally or vertically aligned with the endpoint or midpoint of a line or reference plane, then the dashed lines are displayed. These dashed lines are called alignment indicators and are used to indicate the horizontal or vertical alignment of the current location of the cursor with a point. Figure 2-11 shows the alignment indicators originating from the endpoints of the existing lines.

      Tip. If the alignment indicator is not displayed, move the cursor over the entity from which you want the alignment indicator to originate; the entity will turn orange in color and the alignment indicator will be displayed.

      Drawing Tangent and Normal Arcs

      As mentioned earlier, you can draw a tangent or a normal arc by using the Line tool. To draw an arc when the Line tool is active, press the A key or choose the Arc button from the command bar. On doing so, you will notice that the Length and Angle edit boxes in the command bar are replaced by the Radius and Sweep edit boxes, respectively. These edit boxes can be used to define the radius and the included angle of the resulting arc.

      Also, a small circle will be displayed at the start point of the arc. This circle is divided into four regions. These regions are called intent zones and are used to define the type of the arc to be created. To create an arc tangent to a line, move the cursor through a small distance in the zone that is tangent to the line; the tangent arc will be displayed. Next, click to specify the endpoint of the arc. Similarly, if you move the cursor in the zone that is normal to the line, the normal arc will be displayed. Next, click to specify the endpoint of the arc. After drawing the required arc, the system will automatically switch back to the line mode. You can activate the line mode or the arc mode by pressing the L or the A key, respectively. Figure 2-12 shows a tangent arc being drawn using the Line tool.

      Tip. If you have selected an incorrect point as the start point of a line, right-click to cancel it; you will again be prompted to specify the first point of the line.

      The buttons in the Line command bar are used to specify the color, type, and width of lines. You can also draw a projection line of infinite length by choosing the Projection Line button from the Line command bar. Projection lines are generally used in the Draft environment.
