I have searched around to try to find the answer, but can only find far more complex issues. I have two walls that meet at a corner, and ArchiCAD has not joined them. I want to join them. They are the same type, height and thickness. I just want them joined to form a corner, rather than having them as two overlapping walls. I've tried dragging the walls away then back again, hoping ArchiCAD realises they can't physically occupy the same space, but no, ArchiCAD's too stupid for that. Design > Complex Profiles > Merge walls does nothing (not even an error message, just absolutely nothing. Useless). As far as I can tell, this is for merging walls next to/parallel to each other anyway.
The ArchiCAD help goes on for pages about connecting differing walls in complex situations, but I want an equivalent of AutoCAD Achitectural Desktop's simple T-wall join or L-wall join thing which was incredibly easy (and that was about 8 years ago - the last time I used that (far superior) program).
Any help would be greatly appreciated. Please!
