Managing Product Structure:
Here are some basic rules you should know before handling
the different types of files available in the Product Structure workbench:
- No distinction is made between assemblies, subassemblies, and
components in the description of the product structure. However, you can
associate a geometric representation to one component only.
- If two instances of the same component are used in an assembly, there
is only one reference component for both instances, i.e. any
modifications to the reference affect every instance, except name,
representation activation and design mode visualization.
- An assembly is contained in a unique CATProduct file. The references
of components and subassemblies can be contained in the same file as the
assembly or in different CATProduct files.
- If the reference is contained in the same file, the component can be
used only in this assembly or in larger assemblies containing this
- If the reference is contained in a different file, the component can
be used in any assembly, but this file is then dedicated to this
- When you use a file as a representation, i.e., a .model, .cgr or .ncgm
document, assembly data i.e. the part number, the definition, etc. is
saved in a different CATProduct file.
- A CATPart file contains the assembly data related to the part and the
reference of this component.
