I have a file obtained from 3D Slicer.

Using blender I converted this file to STL and other ones.

In Solidworks 2013 I could not open the STL as a part/solid. It appears a waning saying the piece has too many faces.

I tried this option https://forum.solidworks.com/message/229516#229516 using MeshLab

When I tried to open in solidworks the file obtained from MeshLab in .DXF, solidworks freezes and shuts down.

Is there any other way to convert the file from 3D Slicer to a part for Solidworks in order to handle and model it? (Cut, extrude, draw....)

Thanks in advance
