Got much better over the years
Everything Solids from VW here,
which is absolutely phantastic !
First it looked like I got even Wall and Slab Compositions in.
Which is nearly true (for singly-Ply Compositions).
Just that for Walls I don't get multi-Ply Compositions in but multiple
So not my complete VW Wall Style but a BC Composition from each
of my Wall Components (which each use their own "Material"Layer)
And what looked like a multi-Ply Composition Wall Solid is in fact a Block,
of multiple ntimes separate Solids, from ntimes Wall Components.
As I always wondered why I get so many single-used Blocks for things
like Slabs or Walls.
And imported Compositions are all generic, separation in Walls or Slabs
So import of Plies instead of whole Compositions brought another Problem
While Import I was asked - and skipped - Duplicates of the "same"
But that was not only the Plaster "Building Material" but in fact the whole
Ply Setting including different Thickness, used in multiple multiple unique
Plaster Walls with different Thicknesses.
For my Slabs the multi-Ply Composition came in as such.
Although I do not know how that will work as the Slabs are also Blocks
from a separate Solid for each Ply.
The Block is the BIM Slab ! Inside the Block are just standard non
classifiable Solids. So the "Block" thinks it had a Composition !?)
So my Question, is that something :
a) not our fault, VW must export bad IFC, it works for us
b) we are well aware of that, this feature will come in future releases
c) this is that way up to IFC 2x3, you should better try exporting IFC 4.0 to Bricscad
d) you should use "simplified geometry" Option for exporting multi-Component
Objects for now ....
