Hard and soft surface drawing papers are recommended for drafting. Pencils need to be sharpened when dull and come in various grades depending on the type of line work and paper. Common drafting tools include T-squares, triangles, compasses, protractors, and erasers which are used to accurately draw lines, arcs, circles, and erase mistakes.
