Render Material Imports - DWG and IFC
Somehow I haven't been able to see Render Material Assignments,
from my clients Revit Exports, in Bricscad.
- DWG - Assignment
Materials are somewhat imported, but no Assignment at all.
All Entities are set to "By Layer".
But I think that is not true.
In this case,
the few Layers are used for Objects with multiple Materials,
like a whole Curtaiun Wall System, Glas Panels and Beams.
Also each Entity has its Color assigned by Objects
(Which fits to different Material usage, from my experience)
So I assume that all Materials are applied "By Object"
but Bricscad generally skips such Assignment and always sets
it to "By Layer " instead.
- DWG - Materials
There come in far more Materials in DWG than there are in reality.
In IFC/DAE I have about 75 different Materials, in DWG there are
about 750 Materials !?
They all come in like :
RevitMaterialDefinition9891450_1208558
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 :
RevitMaterialDefinition9891450_XXXXXXXX
should in fact be a single Material only,
where the XXXXXXXX number describe just the Material Shader Slot like :
RevitMaterialDefinition9891450_Diffuse
RevitMaterialDefinition9891450_Bump
RevitMaterialDefinition9891450_Transparency
.....
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 ?)

To add,
for IFC,
Physical Materials are imported by Compositions.
But they don't have the Render Materials assigned to them ...0
