I’ve been using the brilliant Steam Node Tool.ExportDWF to export a bunch of 3D views to DWFx to link into Navisworks. It works great, but I’ve just noticed it exports everything in colour apart from ducts!
If I export my ductwork view to DWF from Revit the colours are visible, but when I do it from Dynamo the ducts are white and I can’t figure out why.
