Hi,

I have a an IFC file that represents a bridge. The IFC file also contains damages wich are shown as openings in the bridge.

I need to convert this file into a Caesium 3D tiles file. I thought that I could just read the IFC and write into Caesium but this did not work. I did some reasearch but did not fin anything for this problem. I did find a tutorial form IFC to CityGML and there they used a Triangulator. So I added a Triangulator between the Reader and the Writer and it worked.

But the damages were not shown as openings. I looked at the parameter and it made no difference if "Subtract Opening Geometries" is set to Yes or No. I tired a CSG Builder with the difference output (with and without a SolidBuilder before it) but that also did not help.

Does anybody know how to selve this?

thanks for any help
