Dwg export, layer control like IFC

Could we add functionality to the dwg export so that there is layer control similar to what we have for IFC? Maybe this is a rhino thing more than a visualarq thing.

I had a meeting with my structural engineers this morning, and they reference in my dwg exports and turn off the finish layers. Sometimes the overlapping lines from the finish layers and structural layers (the inside face of gypsum wallboard and outside face of a stud for instance) have hierarchy issues and only the wallboard is exported. Then, when you turn off the wall finish layer there is nothing on the wall structure layer.

I haven’t been able to replicate the issue on my machine, but would prefer to just keep it simple for them if possible.

IFC allows us to save out individual layers as part of the export commend. Could we get a similar option in a dwg export?

Hi @arcus the Layer visibility per Detail is meant to be used to control which objects (lines) are exported and which aren’t in each detail view, isn’t it?

Do you have an example of it? I’ve tested it and the overlapping lines of two different wall layers are preserved in the DWG file (and also their Layer, so you can turn one off and see the other one).

Yes, the Layer Visibility per Detail is super helpful and is a huge improvement in Rhino 8.
I’m specifically referring to exporting several 2d Plan Views and Section Views at once as a 2d background in dwg format. I can hide the layers and update the Plan Views and Section Views, the turn back on the layers, but it is a bit tedious. It would be great if there was a way to control which layers exported based on some kind of predetermined dwg Export Scheme.

I would send you a file, but I can’t seem to replicate the issue they were seeing either. In fact, we had the meeting in their office and they couldn’t show me an exact example. :person_shrugging:

Regardless, it would be a helpful feature to have when exporting dwgs.

All right @arcus, I take note of this feature-request for future versions.

Awesome, thanks so much!
