Multibody Overview

You can manipulate multibody solids the same ways you manipulate single solid bodies. For example, you can add and modify features, and change the names and colors of each solid body.

A folder named Solid Bodies appears in the FeatureManager design tree when there are solid bodies in a single part document. The number of solid bodies in the part document is displayed in parentheses next to the Solid Bodies folder . You can organize and manage solid bodies in the following ways:

•   Group bodies into folders in the Solid Bodies folder . 

• Select commands to apply to all bodies within a folder.

• List features that belong to each body.

You can create multiple solid bodies from a single feature with the following commands:

•   Extrude boss and cut (including thin features) 

• Revolve boss and cut (including thin features)

• Sweep boss and cut (including thin features)

• Surface cut

• Boss and cut thicken

• Cavity

Modeling techniques that you can use in a multibody environment include the following:

•   Bridging 

• Local Operations

• Symmetry Modeling

• Body Intersection

• Tool Body Modeling

• Multibody Versus Assemblies
