Can you attach the file here?
Can you start a new sketch and Convert Entities to project an outline of the perimeter into sketch for extrusion?
I will try your suggestion first. Thank you! Will let you know how it goes.
You have not supplied very much information about this file.
1. How big is the file?
2. Is it 2d or 3d?
3. What is the source? (Point cloud?)
The original file was created using MicroCT. It was outputed as an STL. I then used MeshLab to create a dxf file. Then I took the 3D mesh and imported it as a 2D sketch into solidworks. I then saved it as a 2D solidworks part.
The original STL file was 75MB
DXF was 82MB
Solidworks part was 150MB.
