Figure 1.15 Size and skew the right side of the dimetric drawing.
Step 5: Add the left leg thickness
The left rear leg of the desk is only partially defined. If we had a back view available,
we could use it to give the leg thickness. Since we don't, let's try what we have done
before by copying and pasting the front view and then moving the copy into position
to define the leg. As before, choose Modify > Arrange > Send to Back to get the front
copy behind the original.
Unlike earlier, we still have a problem. The duplicated front needs to be behind every-
thing. We can easily solve this by adding a new “back” layer between the text layer
and the left layer and pasting the copy into the new layer as shown in Figure 1.16.
Figure 1.16 Place the front copy on a separate layer below the others.
