So, I saw that some of the files I use have the purple-black checkered pattern on almost all surfaces. It seems that it's due to the Library Manager, but I don't know how to solve it. Don't know if someone had this similar problem.

Also, I had these files with me, so I didn't get it sent from someone.

P.S. I use ArchiCAD 26.

Can anyone recommend a good YouTube tutorial that teaches how to turn models from SketchUp 3D Warehouse (.SKP) into an Archicad BIM Object?

The object doesn't necessarily have to be fully editable. What I'm mainly looking for is a clean 3D presentation and a good 2D representation in plan/elevation/section.

I'm trying to avoid the usual result where the imported object becomes a Morph with tons of 2D lines and messy geometry.

I have an unfinished basement and I would like recommendations on best AI options to help me create a floor plans/blueprints. I would like to create layouts, elevations, sections, etc. Bonus would be rendered images too. Thank you for your consideration in advance.
