Thanks for the suggestion. Unfortunately, this hasn't solved the problem though. It seems that the Sketch-Up plugin has been integrated into ArchiCAD since version 17. I am running ArchiCAD 18 and so I assume it is already built-in.
I just need some guidance on how to use it, or to do it in some other way.
Any other suggestions folks?
