Get all curtain walls placed in project

[vanman]

Hi,

I’ve been struggling with this to long. Whats the most reliable way to get all placed curtain walls in the project. The curtain wall type is all different names so cant use that.

What error are you getting on Collector.CurtainWalls and Element.IsCurtainWall?

You have in place families in your project. This should do it.

I’d recommend filtering on the wall type level before starting to collect wall instances - should be faster on large projects:
