Hello @GH007 !
We recently changed the behavior of BIM schema components in grasshopper to give users the option of sending their walls, for example:
- as a
- as a
Geometry object with a
Wall schema attached.
The reason you are seeing a “No displayable objects” error in the viewer is because by default all generated components are set to option 1, and since the wall was generated in GH it doesn’t come with any display meshes attached (unlike when they are sent from Revit, where the wall geometry is already created).
If you manually select option 2, you should see the surface input parameter rendered in the viewer and no longer get that error message:
Either way, you shouldn’t have any trouble actually receiving the wall object even with the viewer error - it should still be properly generated and created if you try to receive it in Revit! Let us know if this isn’t the case.
We may make a note to either add a remark in GH when using option 1 on schema objects so the displayable error doesn’t confuse users, or improve our components to generate display meshes from input geometry when possible with option 1
