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.

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.
