I have a friend who has imported DFX files into Solidworks.He is using version 2013. The problem is that in solidworks the surfaces are smooth and when inported they become segments. How to make the surface smooth.
I'm confused. You say that your friend imports DXF files into SolidWorks, then you say that in SolidWorks the surfaces are smooth and when imported they become segments. Are they smooth in DXF and segmented in SolidWorks?
You actually wrote DFX and I am assuming that you mean DXF. As far as I know, SolidWorks only imports 2D DXF files, so how are you getting surfaces?
