Drawing Problems
Start AutoCAD if it is not already started. Start a new drawing for each problem using an appro-
priate template of your choice. The template should include layers and text styles for drawing the
given objects. Add layers and text styles as needed. Draw all objects using appropriate layers. Use
appropriate text styles, justification, and format. Follow the specific instructions for each problem.
Use only drawing and editing commands and techniques you have already learned. Do not draw
dimensions. Use your own judgment and approximate dimensions when necessary.
