Chapter 26: Modeling Multi-bodies

The image to the right in Figure 26.3 shows transparent surface bodies that were used to split the

model into separate bodies using the Split features shown in the tree. Using this technique, you

can create the overall shape as a single piece and then split it into separate parts. It is also possible

to apply this technique in the context of an assembly, but this method is far more direct.

FIGURE 26.3

Splitting the part into bodies

To go from the multi-body part created here to a set of separate parts uses a Master Model

function, which is described in Chapter 28.

Using Tool bodies and Boolean operations

Some features require multiple bodies within a part, such as the Indent and Combine features,

among others. Using one body to create a shape in another is a common use for bodies within a

part.

Indent feature ..........................................................................................................

The Indent feature is covered briefly in Chapter 7 before multi-bodies are introduced, so it is
fitting that I revisit it here so that you can better understand the multi-body aspect of its use. The
Indent feature indents the target body with the tool body. It can also use another part in the context
of an assembly as the tool. The indentation can exactly fit the form of the tool, or there can be a
gap around the tool. You can also control the thickness of the material around the indent. A
further option is to simply cut the target with the tool instead of indenting.

Figure 26.4 shows the target part as transparent, and the tool as opaque, before and after the

Indent feature has been applied. The Indent PropertyManager is also shown.
