CONCLUSION:

1. The first thing that you would do, to create a "Coat Hanger", would to create a triangle.  THEN, you would filet the edges, so then you have a triangle, with rounded edges.  Then, you could create a point, and arch it, then a line from one part of the arch, to the triangle.

2. The Thread function could be used, to create a spindle on a wooden handle.

3. The CAD Software easily makes changes, by adding and subtracting 3-D Objects from the area.

4. If something was added, on a 2D Sketch, they could delete the addition.  Otherwise, the only other way to undo, besides the undo functgion itself, would be CTRL + Z.
