Hi, we've commissioned a 3D context model from a third party supplier. They sent it to us as a Sketchup (SKP) file, which seems to be a pretty common format with that type of service.
I've opened it in ArchiCAD 21 (which converts it to an object). I've then tried converting the object to morphs so that we can work with the data. Once it's finished the process, it seems to convert most, but deletes all vertical faces, which is very unhelpful - this equates to all walls, chimneys, etc. Landscaping, trees and roofs are converted fine.
Any idea why this is happening? Or what I can do to fix it?
