How to reduce the time of regeneration of a generic model with many instances?

Some other techniques to try

For parts:
Keep all of the non-changing features at the top of the model tree leaving just the variable features at the bottom.  This may keep the non-changing features from regenerating each time an instance is opened.  This may require that you reorder the features and/or re-define existing features to split the geometry into multiple features.  For example: if you model a bolt where only the length of the bolt is changing in the family table, model all of the features that define the head first, and then, as the last feature, define the shaft portion.  When you verify the instances, only the shaft geometry should regenerate.  That is a very simple example, but if your first feature in a 100+ feature model is variable, the entire model may regenerate for each instance causing longer regeneration times.

For assemblies:

1. Try the same technique listed for parts, keeping the non-variable components at the top of the model tree.
2. If you're swapping out components and their related mounting HW components, try grouping them and placing the group in the family table.  If nothing else, it organizes the model and family table better.
3. Check your assemblies for circular references.
4. Check for external dependencies.
5. Don't use assembly level cuts that only show at the assembly level.
6. If you're using skeleton models that have family tables to drive component placement, this may drive the entire assembly to regenerate as the skeleton is the first model in the model tree.  Try creating the family table inside of the .asm file itself instead of in the skeleton model.
