1. It would be nice if importing DWG files would also be supported not only DXF
2. If you get DXF files from outside (from the customer) there are usually several views available.
From the front, from the side, isometric, etc.
There should be the possibility to select only one area from the DXF.
Either you select a chain and it uses the chain and everything within the chain or you pull a window with the mouse or even better you click a poligon together and it takes everything that is inside the polygon / window.
Of course you should be able to deactivate unimportant layers (centerlines, text etc.) during import.
You should also be able to change the scale later. Sometimes the top view you need is displayed on a different scale.
If you produce for other companies the module does not make sense at the moment because you have to remove all unneeded information before importing the DXF.
