3DCS in CATIA V5 Tree Modification, Part 1
Replacing significantly modified subassemblies in CATIA
What happens when you delete and replace a subassembly with one that reflects a different process?
Many hours can be invested and lost trying to replace a heavily modified subassembly using the CATIA commands and the Tree Link Wizard. Furthermore, this method can cause excessive loss of feature links. The Tree Link Wizard is meant for updating the model after a single part or sub-assembly is moved or replaced. In fact, when moving multiple sub-assemblies, Update Model and the Tree Link Wizard should be used between each step.
This Tips and Tactics is a work around to get your subassembly with 3DCS replaced and updated without tree linking and feature linking. If you’re just replacing the same subassembly without name or structure changes, this work around usually isn’t necessary.
With this work around, MTMs at the higher assembly levels will need to be checked and possibly corrected. 3DCS Excel export can be used to easily fill in some vacancies caused by this work around since some MTM items (Moves, Tolerances, and Measures) will likely be left with missing Object and Target points.
