Problems

Create one drawing file for each numbered problem. You can create your own file names for these problems. For example, problem 1 below will be saved in unit 2 as prb1-1,etc. You should have saved six problems as presented below for you to draw. Drawing on a grid with the snap mode on is much easier. To set snap and grid click on Options and Drawing aids in the menu bar.Turn the snap and grid on and set the X and Y spacings for .25 each and enter OK. The drawing aids box is shown below.

The grid will now appear on your screen and the snap allows you to move from dot to dot drawing with accuracy. If the grid does not expand across the entire drawing area then click on view and then toolbars and scroll down to UCS. Click on the box which will place and "X" and then "ok" as shown below. Place this toolbar on the right side of the drawing area with the other toolbars. Click on the green icon wpe4.jpg (945 bytes) in the UCS toolbar and then click on your screen or drawing area. You'll now notice the entire area has the grid. Horay!
