Hello,
- I would like the Revit Reader to be able to expose different part (material) layers, for example in: Walls, slabs, roofs.

- Right now (FME 2020.0), we get a single surface:

- The use case:
Doing basic quantity takeoffs. I was showing FME to some project managers and they were kind of speechless. I managed to automate basic cost estimation, in one afternoon.
The only puzzle piece missing were different material layers (structure, insulation, etc). Those are separate cost classes (makes sense).
So, I know this is kind of hard...
- As a workaround:
Being able to read Revit schedules for material takeoffs would get the job done as well.
That would be AMAZING!
- As a side note: We would only care about the information (layer name, material, position and quantities), not geometry.
