I'm making a model of an electronics enclosure. The box is extruded aluminium and I have a DXF file from the manufacturer with the 2D profile of the box.
I've used a copy of TurboCad to export it to a SketchUp file and then imported into DesignSpark.
It loads ok as a sketch in a plane, but it is made up of lots of individual line segments and arcs which seems to prevent me ffrom being able to use the pull tool on it. I'd like DS to recognise it as a single polyline with an interior face that can be pulled.
