array with .75″ (19 mm) spacing between objects. What should you specify for the ″
distance between columns?
11. Define associative array.
12. How do you specify a clockwise circular array rotation?
13. What value should you specify for the angle to fill to create a complete circular array?

Drawing Problems
Start AutoCAD if it is not already started. Start a new drawing for each problem using an
appropriate template of your choice. The template should include layers and text styles for draw-
ing the given objects. Add layers and text styles as needed. Draw all objects using appropriate
layers, 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.

Basic
1. Open
P11-1
and save the file as P12-1. (If you have not yet completed Problem 11-1,
do so now.) The
P12-1
file should be active. Rotate the object 90° to the right and
mirror the object to the left. Use the vertical base of the object as the mirror line.
The final drawing should look like the example below. Resave the drawing.
