I need to produce closed polylines that are encoded/recognizable as a closed thing by POLYLINE or LWPOLYLINE elements in the DXF file.
I have tried (and found frustrating) QCad Demo 18.104.22.168. There is a "Close" Button when drawing Lines, but the whole thing comes as a bunch of single LINE elements in DXF.

--> Is that a bug or a feature?

Yeah. The DXF stuff gets translated into a Tk Canvas graphics, which does the filling iff the polyline is closed. No need for these triangle fillings with DXF SOLID elements, and more performant e.g. when zooming.andrew wrote:Apparently in your special case it seems to matter.
