Editing Solids
Basic solid forms are fairly easy to create. Refi ning those forms requires some special tools. In the
following sections, you'll learn how to use familiar 2D editing tools, as well as some new tools, to
edit a solid. You'll also be introduced to the Slice tool, which lets you cut a solid into two pieces.
Splitting a Solid into Two Pieces
One of the more common solid-editing tools you'll use is the Slice tool. As you may guess from
its name, Slice enables you to cut a solid into two pieces. The following exercise demonstrates
how it works:
1.

2.
Click the Slice tool from the Solids - Edit tool group (Figure 22.16), or type

At the Select objects to slice: prompt, click the model and press ↵. Note that if
you need to, you could select more than one solid at this prompt. The Slice command
would then slice all the solids through the plane indicated in steps 4 and 5. For now,
you're just selecting one solid.
