PURGE UNUSED - REVIT API

[Anonymous]

Please add purge unused revit families to revit api!

And if you wont I will see you in the argument clinic or the revit one, no time limit.

I have found an existing simple solution for this (for Revit 2017+). See my code repository:

Congrats! We think this is a great idea, so we've decided to add it to our roadmap. Thanks for the suggestion!

@matthew_taylor ,

Thank you for the reference. As this is specifically API related and already accepted, I am going to keep this Idea separate.

@matthew_taylor does your code work with specific categories? For example I want to just purge unused doors.

[matthew_taylor]

@tom_flaherty No. You would need to post-process the element IDs to check their category.
Note that in Revit 2024 there are two new functions for getting unused elements:

• GetUnusedElements
• GetAllUnusedElements

We are pleased to say that this has been implemented in Revit 2024! Thank you for your contribution to improving Revit!
