Somehow I haven't been able to see Render Material Assignments,
from my clients Revit Exports, in Bricscad.
So I assume that all Materials are applied "By Object"
but Bricscad generally skips such Assignment and always sets
it to "By Layer " instead.
What I notice is that there are often Duplicate Materials (up to 4 ?)
for the first number block, they only differ in the 2nd number block.
And given the names of the (missing) Immage Textures,
I come to the conclusion that all :
should in fact be a single Material only,
where the XXXXXXXX number describe just the Material Shader Slot like :
Also they miss their proper "human readable" naming.
(Not sure if it got skipped or isn't in DWG)
IFC - Assignment
Unfortunately, again, all Material's Assignments lost.
IFC - Materials
Material Import looks much better.
- Only a single Material Definition for each Material
- human readable Materal Naming
Unfortunately all Texture Assignments/Paths got lost.
(Does that require IFC 4.0 ?
Or was that just needed for embeddeing Image Texture Files into IFC ?)
