Modify Instance Definition Slow

Using the, InstanceDefinitions.ModifyGeometry() to modify multiple blocks with python in a command. sometimes it is very fast and other times it is very very slow. Are there any tricks or tips to improve performance? Thanks!

Sorry - no tricks.

Can you provide a way for us to repeat this slowness?

Yes I can get something together soon. For what its worth, I have done experimenting and found that the ModifyGeometry() method is only ever slow when it is modifying a block that has been nested inside of other blocks. Thankfully in my case these blocks are not meant to change every time the command was run, so I just was able to reference the existing block definition instead of re-defining them.
