i think, more work should be done on " HOW TO EXTRACT QUANTITIES "
the " material based workflow" is genial, and gives us a good takeoff workflow
John, from CONTRABIM, did a great work on quantity takeoffs and cost estimation with ArchiCAD,
schedules, combined with proreties can do a lot of smart calculations.
for some components, takeoffs are limited, for technical reasons of course, or a bit complicated, like stairs, railings, curtain walls, shells, objects, etc
ArchiCAD should release a version where it refurbish it's existant tools, before thinking about adding new ones
Walls, slabs, roofs, doors and windows, zones, should be renewed,
