I will read more about Revit 2015. I heard they are into 3D printing --
Glad you bring up some old issues from ArchiCAD. I really am hoping there are more improvements on CurtainWall, Stairs, Escalator, Interactive Schedule List, and Yes GDL scripting! OMG it is very powerful but it is just so old school. Not all can do GDL as a resort they make use of Morph tool to achieve the 3D look. But then again it is not parametric so info such as manufacture details, etc is difficult to include in the object.
