Presenting Blender as a new IFC authoring tool

@Moult
i’m having hard time understanding the advantages of blender for architectural activity, and, beside obvious advantages (free modelling of everything, free assignment of data, either relational, or not) i’m missing significant issues, which might be based on my lacking deeper knowledge of blender, though.

what i miss are first of all intelligent systems that understand one another: eg. windows in the walls (including components overwrapping), flat roof drainage, which adjusts particular roof components for the slopes, automatic roof/walls framer, curtain walls with automatic edition of elements, and many, many others.

at first glance the architectural/structural modelling in blender is a cumbersome act.
am i missing something?
