Error in IFC to XKT Conversion: "No basis found for brep"

[laguisse]

Hi,

I’m trying to convert an IFC file to XKT using the xeokit-convert tool, but I’m encountering an issue during the conversion process. Here are the details:

When running the command:
node convert2xkt.js -s WPM-NTO-CAE-STR-M3D-00000.ifc -o WPM-NTO-CAE-STR-M3D-00000.ifc.xkt -l

I receive repeated error messages in the output:
ERROR: No basis found for brep!

This error occurs multiple times throughout the conversion process. Despite this, the conversion finishes, and the XKT file is generated, but I am concerned that the error might indicate that parts of the IFC model are not being converted properly.

Here are some details from the output:

File: WPM-NTO-CAE-STR-M3D-00000.ifc
Size: 40076.42 kB
XKT size: 1446.00 kB
Converted objects: 569
Converted triangles: 170967
Converted geometries: 562
Could you please help me understand what the error means and whether it impacts the accuracy of the conversion? Is there a configuration or adjustment I need to make to ensure the conversion handles the brep geometry correctly?

Thank you for your help!
