I wonder what “Use model extensions” means?
Found in the Print window under print size.
Thank you for your time!
If you mean the tick box on the Print dialog, you have misread. “Use model extents” should fit the model on your print page automatically. It works if you are printing a model larger than about 300 mm across to a scale that is not 1:1. It has a bug that is at least 17 years old that makes it not work for printing small objects to full scale.
Sorry I use google translate.
Thank you very much for your help and time.
