Export only necessary geometry!

1. Hide (or delete) everything ,Curves, Dimensions, Circles, Lights excepts the surfaces!

2.  File > Export > Rapid Protoype

3. Drag select your Surfaces and Accept the Stitch Tolerance

Tip:

The Stitch Tolerance can be adjusted to "bridge" over gaps and edge problems. A possibly cheating tool :)

It´s okey with Yellow (Naked Edges) because we do not need a leakage free 3D-volume when Milling
(3D printing demands a leakage free model!).

We can even have small gaps as long as they are smaller than the choosen milling tool.
Milling is "friendly".

4. Decide the Quality of the Mesh

This Tolerance is the max deviation you can accept between the original NURBS surface and the polygon Mesh.
Smaller Tolerance value = higher Quality

Max Edge Length avoids having very "stretched" polygon (triangles)
Smaller Max Edge Length value = higher Quality

5. Wrong Normals?!

If Yellow surfaces seen from the Top View (milling direction) then flip them with the Use of Surface Normal Tool.

(Alias: Surface Edit > Orientation > Set Geometric Surface Orientation)

6. Check the Mesh Quality

Zoom in on a curved surface and decide if you need more polygons.

BUT try to keep the file size below 20mb

For simple geomtery (the MC-fairing) that is not a problem at all :)

7. Improve the Mesh Quality

Adjust:

• Tolerance

• Max Edge Length

Update and examine!

BUT try to keep the STL-file size below 20mb

8. Export the Mesh as a STL-File

And check that the STL-file size is below 20mb

Usually never over 50 mb

Over 100 mb is embarrassing!  :)
