Revit 2026.3 - FamilyType.CompoundStructureLayers

Hi. I am trying to extract information about materials from walls and floors but the Family.Type.CompoundStructureLayers node is not working for me. Can someone check whether this node works in Revit 2026.3.

Likely you’re looking at something built on the old and unsupported IronPython2 engine. Long past time to move to something which uses a supported.

Which package is this in? Clockwork? Genius Loci? Something else?

Clockwork
Is there any other way to read these materials in Revit 2026 ?

Which version of clockwork are you using?

Edit to add: You likely want version 3.3.0 of the package Clockwork for Dynamo 3.x.

Bad Clockwork version was a case. Thanks !
