Export IFC GUID as mesh name (instead of IfcName + EntityLabel)

[Hafplo]

Currently the GLTF file creates meshes and populates the 'name' property with the IfcName of the element + the IfcEntityLabel of the element (the "row number" in the IFC file)

since names don't follow any convention, I believe it is more robust to use the IfcGUID instead.
IfcGUID is unique per element, and doesn't change in cases of minor changes to the IFC file (i.e. authoring or editing), while the name can change (i.e. changing the convention, translating) and entity labels can also change.

Also IfcGUID is mandatory for all elements and objects.

Hello @Hafplo,

thanks for the feedback, are you referring to the nodes ?
Nodes currently have this type of name:

{
  "matrix": [
	0.0, 	-1.0, 	0.0,  	0.0, 	1.0, 	0.0, 	0.0, 	0.0, 	0.0, 	0.0, 	1.0, 	0.0, 	2.538, 	-0.417, 	0.0, 	1.0   ],
  "mesh": 4,
  "name": "Basic Wall:Interior - Partition (92mm Stud):138584 #4131"
},

They point to a mesh, and have a name and a matrix.

You're suggesting to have that changed to "name": "2O2Fr$t4X7Zf8NOew3FNld"?

@CBenghi exactly.
GUID should be the identifier for every element. It is more stable and robust.

@CBenghi any updates on this?
