IfcConvert weird result converting IfcGrid for .glb

[berry4u]

I'm having a strange result when using --plan option in order to include IFCGrid elements in glb model.
To reproduce my issue try to convert 01_BIMcollab_Example_ARC.ifc model in this repository
http://smartlab1.elis.ugent.be:8889/IFC-repo/

Doing IfcConvert -j 12 --plan 01_BIMcollab_Example_ARC.ifc test.glb produces no output for me.

If I look at the IFC model, there is one plan context labeled as box, which is a bit weird. Also, the grid geometry invalidly is part of the model context even though it only has XY coordinates. Ping @aothms if he can shed more light, otherwise, I'd say that the grid elements do not have any plan geometry and that's why you're not seeing anything.

I don't see anything weird with --plan --model either.

Except for maybe indeed the boxes that then come along in the conversion output.

yes in fact I really meant the boxes
Moreover, This should be the expected result with captions on the grids placed on each floor

The boxes on the roof are a the bounding box representation and is a duplicate of #2044. It should be a simple fix in IfcConvert in theory. Would you like to try contribute?

The grid captions (numbers and letters) are purely a generated visualisation by your IFC viewer and is not stored in the IFC itself, so that's why it won't show up in the IfcConvert which only looks at IFC geometry.
