AutoCAD - Using modify commands
The document discusses various CAD commands including: object selection methods; erase, extend, and trim tools; duplication techniques like copy, offset, and mirror; and array functions. It provides step-by-step methods for using each command, such as copying an object with a base point or creating a polar array. The document also contains an example problem on drawing projections of a triangular prism and definitions of rectangular and polar arrays.
