I can cut a slab with a mesh and a roof, simultaneously.
I can punch a curved wall with a stamper-object made out of pieces of slabs!
Now, if you think these are no big deal, read the statements again, slowly.
If you still think they are no big deal, stop reading all together.
You are either too young and take every modelling feature offered by whatever software as a given, or too old and don’t really care about the challenges people trying to smartly model construction elements still face.
I know Max can do anything, Cartia and Rhino are magic tools, even good ol’ 3D AutoCAD could reproduce the same, but following these two operations via Archicad my slab stays a slab and the wall is still a wall, even though the slab has a wobbly bottom and the wall looks like a lace curtain.
Experts that preach on the subject of BIM often overlook this ‘type’ of capability of the software they favour (or not);
The ‘data richness’ of a model starts here: a wall has to stay a wall, a slab a slab.
A complex piece of furniture, a bracket or other widget may still get made of ‘construction walls, slabs and roofs’ but by turning them into ‘objects’, this clean logic of virtual-construction-
representation is retained.
A must for any meaningful BIM.
