[BlenderBIM] & IfcOpeningElements
This day I have been trying to use the Blender BIM add-on as an IFC creation tool, instead of an IFC authoring tool as intended at the moment? (please correct me if I'm wrong).
My aim is trying to find a fast workflow for cutting an IfcOpeningElement in Blender while using the IFC model as the single source of truth.
I have modelled a really simple cavity wall in Blender
added a dumb opening from the Blender BIM add-on
Used the IFC Void tool to cut the opening
Exported it to IFC
I think you see where this is going.
I need to add an opening for each wall, which is extremely time consuming.
However when I do this I can parent the IfcOpeningElements, so when moving them don't have to move them all three individually.
I moved the IfcOpeningElement 1 meter, it worked perfect when exporting to IFC
However. Very this method is very time consuming. I know there is Archipack PRO. But I was deliberately avoiding Archipack PRO because I want to use IFC as the single source of truth and not an Archipack or .blend file. Plus I use the parent-object functionality when importing the IFC in Blender again.
I have three questions:
1. Whenever trying to resize the IfcOpeningElements, I all have to resize each three IfcOpeningElements one-by-one. Is there a smarter/better way?
2. When importing the IFC again in Blender to keep the IFC as the single source of truth, I lost my Parent-object (obviously). But the BlenderBIM add-on automatically hides the IfcOpeningElements and does not show the opening:
Also when I click show opening, it does not show the opening in the wall while it's still there.
What is the reason for this?
- Do you have any idea or an approach for a fast workflow in Blender to use just one IfcOpeningElement to cut through multiple IFC elements? No idea if the IFC schema allows it.
