Finding the Interference between Two Solids
In the next exercise, you'll use a tool that is intended to fi nd the interference between two solids.
This is useful if you're working with crowded 3D models and you need to check whether objects
may be interfering with each other. For example, a mechanical designer might want to check to
make sure duct locations aren't passing through a structural beam.
You'll use Interference Checking as a modeling tool to obtain a shape that is a combination of
two solids: the seat and the rectangular solid you just created. Here are the steps:
1. Click the Interference Checking tool near the bottom of the Tool Sets palette. You can
also choose Modify 3D Operations Interference Checking on the menu bar or type
INTERFERE ↵.
2. At the Select first set of objects or [Nested selection/Settings]: prompt,
select the chair seat solid, and then press ↵.
3. At the Select second set of objects or [Nested selection/checK first set]
<checK>: prompt, click the rectangular solid you created in the previous exercise and
press ↵. The Interference Checking dialog box appears (Figure 20.38), and the drawing
temporarily changes to a view similar to the Realistic visual style.
