Materials and intersection priority with meshes

[Paul King]

Looking for a way to overcome the design defects/limitations in ArchiCAD's handling of materials / intersections priority in relation to meshes.

In particular I need a way to have some translucent slabs and roof elements cut a terrain mesh when switched on, but not cut the terrain mesh when switched off again in a given saved view.  

This is for a schematic design visualisation, showing a sequence of things happening on a large complex terrain, as well as permutations and combinations of those things, all for a range of completely different options.  I have never really managed to use the Design Options tool very successfully (mostly due to my lack of experience with it) but I suspect this will not suffice to deliver the flexibility and simplicity needed here to allow any one of the 40 cut terrain permutations and combinations to activate at will, on the fly, in front of an audience, 

I really don't want to make 40 copies of this large complex site to handle each permutation via SEO.

A great idea!  The exercise is done for now, but will keep it in mind for next time.  Crazy that workarounds like this are needed of course, rather than having meshes respect materials - an awful lot of any building is effectively underground.
