Ich habe Auch versucht die beiden Datein in mpr um zu wandeln. Leider habe ich auch das Problem mit dem zu Ordnung der Layer.
Here is an example. You can import dxf images using general import without specifying layers.
After importing, change the cad lines to the bottom level, for example. Use command "create curves by projection on level"
thank you for your prompt answer. I´ll try to follow your instructions. I already had been able to import the layers into woodwop, but your advice on creating curves by projection on level was very helpful. So I´ll try it again.
