First I would like to introduce myself. I am a 23 year old building engineer from the Netherlands. At this moment I am working on a DIY camp trailer.
I have designed this with my own building CAD-software and created a DXF file from it. For the CNC milling I have to create a .STP file and I am trying to do this with Rhino 3D .
The shape has to be extruded to 15mm, because the base will be made from 15mm plywood. At first I imported the DXF file in Rhino and then I used the tool ‘extrude’. This is the moment when it fails, because the smooth edges turn into angular sides and I have no idea how this could happen. The same thing happened when a friend of mine imported it in SolidWorks. Does anybody know how this could happen? And maybe someone is willing to fix this for me? I have attached the two regarding files.
Thanks in advance,
I need the model in .STP or IGES format.
