Assembly for intersection tool not appearing in selector

[Gradezilla]

Hi All,

I have recently moved to a new computer running Windows 11. I copied the intersection assembly DWG across into the "Metric" folder along with the assembly set XML.

The following only occurs in new drawings created on the new computer. Drawings with intersections in them created on the old computer can still have new intersections created in them.

When trying to create a new intersection no assembly appear in the drop down:

This is the same for both C3D 2025 and 2026. Even the OTB assembly do not appear. I have tried restarts and even setting the "Metric" folder to trusted and on the support path.

Any ideas?

Thanks in advance.

What assemblies do you have within your file that you are trying to assign?  Have you tried doing a reset settings to default to see if perhaps there is some sort of corruption within your profile?
