[Bldg-sim] conversion 3D dxf to gbXML

[Harris Poirazis]

Julian,
We have been working in a pretty complicated (geometry wise) project and we have managed to export .gbxml files to be imported in Design Builder using AutoCAD MEP.
However, there was an issue in DB with the number of vertices in each node (if I remember correctly could not handle more than 3 vertices per node for a building block). We went around this problem by importing it as outline block then cutting it accordingly, then converting it to building block, then adding holes and finally merging the adjacent zones. Long process but eventually it worked. If your geometry is simpler it would not be that difficult.

Best regards,
Harris Poirazis

Hi All,

Does anybody know a good converter from 3D dxf to gbXML ?
Hopefully shareware.
I want to use the gbXML as input to DesignBuilder.
Appreciate your help.
Regards,
            Iulian
