Shrinkwrap assemblies

Use Shrinkwrap to create a simplified single part representation of an assembly to improve capacity and performance in downstream assemblies or applications. Shrinkwrap uses the derived component command in the background to create a single part from an assembly. Shrinkwrap can use existing Design View or Level of Detail representations for maximum efficiency. Only visible components are calculated.

What is a shrinkwrap part?

A shrinkwrap part uses the derived component mechanism to create a simplified part file from an assembly. The shrinkwrap command offers the additional benefits of rule based component and feature removal. A shrinkwrap surface composite (the default setting) creates the smallest file on disk and calculates faster than a shrinkwrap solid. A surface composite uses less memory and provides better performance in consuming assemblies.

A shrinkwrap surface composite retains all the original component appearances and can retain other visual features such as thread graphics. All shrinkwrap parts store the mass properties of the originating assembly if they are calculated before creating the shrinkwrap.

A surface composite part does not participate in interference and collision detection operations. Avoid using composite parts in section views.

What benefits do shrinkwrap parts provide?

Shrinkwrap provides the following benefits:

How do I use a shrinkwrap part in a Level of Detail?

There are three workflows you can use to create a shrinkwrap part and then use it as an assembly substitute in a Level of Detail:

Can I edit a shrinkwrap part?

A shrinkwrap part is a derived part file. To edit it, open the file, and in the browser, right-click the assembly node and choose Edit Shrinkwrap Assembly. A useful technique is to modify the shrinkwrap part after creation until it contains the required amount of detail.

Note: The Edit Derived Assembly command is not available if the part must be updated.
