How do I create write out a 3d polyline?

[mesimms]

I have been experimenting with dxflib to produce 3dpolylines: the LWPOLYLINE generated by writePolyline(), writeVertex() and writePolylineEnd() is of course 2D.

I've tried writing a function to emulate a simple 3D line in an existing DXF file: I don't get why in writePolyline() it automatically writes a LWPOLYLINE, surely full 3Dpolylines were allowed in DXF 2000, (AC1015)?

Does anyone know how to do this?

3d polylines are not supported by dxflib at this point. Support should be relatively easy to add in a similar way as LWPOLYLINE support.

Has anyone added support to create 3D Polylines?
