Issue in SIMPLIFYING THE MODEL

in the instruction of “running isaac sim for the first time”, there is a section called " SIMPLIFYING THE MODEL". It asked me to drag /Root/chassis/electronics into /Root/chassis/body, but it does not allow me to do so. In the Console of Isaac sim, it outputs “Cannot move/rename ancestral prim /Root/chassis/electronics”.

Hope this can give more hints to solve the problem.

Before this, when I tried to use STEP importer, after I click “Finish Import”, I can’t click “Save Flattened”. I can only do it after I select “Built in Step Files”.

Hi,

It seems you can not move/delete, etc. because the entities on your stage are references of external USD models… To modify them, you need to save the model as flattened (Save Flattened) to merge all components into one .usd. Then, open and work on this previously saved and flatten model…

Thank you. It works now.
