XKTEntity has no meshes - Conversion issue

[phxd88]

Hi, I tried convert2xkt.js via command line with a lot of IFC models. The conversion process finishes well but for every model (included sample IFC models: e.g. Duplex, MAP...) different entities are not created. Geometries have been validated and checked well.

Can you help me? thanks

here is the sample of MAP.ifc conversion:

I'm having the same problem. When I run the script to convert from ifc to xkt I get the following log and in the viewer I don't see anything.

Hello guys, any fix for this please?

[xeolabs]

• xeokit-xkt-utils is now replaced by xeokit-convert, which may give better results
• xeokit-xkt-utils and xeokit-convert both use web-ifc internally to parse IFC
• web-ifc appears to have a couple of bugs that prevent it from parsing some IFC, resulting in xeokit needing to log the "XKTEntity has no meshes" error
• web-ifc is in alpha, therefore the direct IFC->XKT conversion option for xeokit-convert is an alpha feature also
