Layer Hierarchy with ggImportIFC

Hi,

I’m trialling the use of ggRhinoIFC for importing IFC models for daylight analysis with Solemma ClimateStudio (a Radiance front-end for Rhino/Grasshopper)…

Importantly, ClimateStudio assigns Radiance materials on a per-layer basis (Rhino layers), in its own dialogs, indepenent of Rhino’s materials system.

Previously I’ve got my models into Rhino by exporting them from Revit as DWGs with a layer schema that breaks down the models per element types (not spatial hierarchy) which has worked sufficiently well. If I received an IFC model, I would import to Revit and then export to DWG.

With ggRhinoIFC, layer generation with the HierarchyIFC setting results in Rhino layers which aren’t useful for my use-case. The ‘Assigned’ setting gets me closer but in the cases I’ve looked at still not granular enough (e.g. window frames and window glass appears in a layer BWallExternal.

So after all that, my question is this:

Is there a way with ggRhinoIFC to set a custom layer schema for import, that can give me layers on a more per-element-type and/or per-material basis? Is there an example of this available at all?

(Note - I’m not needing to retain IFC structure / attributes for re-export to other software - this is just an analysis task.)

Thanks in advance

Carl

Hi Carl,

Thanks for the post. Is it possible to share a sample model? Where is it sourced from?
You can share the model privately via email rather than post to the forum.

Thanks,

Jon
