[QGIS-Developer] Loading DXF in QGIS?

[Stefan Giese (WhereGroup)]

Hi,

with ezdxf you can do the job. The following snippet shows how it works:

/......
/

/#Reading the dxf and get the modelspace
     dwg = ezdxf.readfile(filepath)
     msp = dwg.modelspace()

     #loop through all Polylines of the DXF
     polylines = msp.query('POLYLINE')
     for polyline in polylines:/

/       # for example converts a dxf Polyline to a QgsGeometry (Polygon)
        points = []
        for i, location in enumerate(polyline.points()):
            points.append(QgsPointXY(location[0],location[1]))
       polygon = QgsGeometry.fromPolygonXY([points])/

/.....
/

hope this will be a starting point for you...

Mit freundlichen Grüßen
