EDIT: I shut down AOL, ArchiCAD, etc and rebooted my computer, opened ArchiCAD w/ new Project and Profile settings w/o AOL and the Model Tab has returned (and the Ifc2.0 has disappeared) In case this might help someone else, I have left the original question:
I hope this isn't a stupid question but I also hope there's an easy answer.
I have been working my way thru the tutorials and was trying to make a window using the wall and slab tools but when I went to the Wall Default Settings dialog box, I find that the Model tab that would allow me to set the materials has disappeared. Instead, there is a tab that says Ifc2.0 that I don't remember seeing.
When I open the settings boxes for windows or slabs, etc., the Model tab is there and there is no equivalent to the Ifc2.0. I have also closed out of ArchiCAD and reopened it but nothing changed.
Has my file been corrupted or am I doing something incredibly 'newbie"?
Thanks
