Oh, my God, ArchiCAD sucks so badly.
I've had to use ArchiCAD for the last 2 years and it just sucks so immensly, I can't grasp how much it sucks.
Is it good for anything? Yes, sadly, but it's not made by anyone who ever used parametric CAD before, that's for sure.
I've also had the pleasure of learning Onshape recently and I must say, this is the polar opposite. It's just the most pleasure to work with. Sure, I still have to use this behemoth suck called ArchiCAD, cause Onshape can't do the things ArchiCAD does, at least not in a BIM way.
