<br>
Thank you for the quick reply.<br>
<br>
I took exactly the same settings you sent me, and it worked.<br>
Then I saved the mesh (File-> Save Mesh).<br>
But now, whenever I try to open the same .stl file again (wind.stl), my Gmsh gets crashed on the very beginning. Why is that so?<o:p></o:p></span></p>

I have one issue though - I can not generate 3d mesh on my wing model. Check the attached files (the wing was created in Rhino5, that's the .3dm file.) I am also sending you exporte .igs and .stp versions of the original .3dm file.<br>
<br>
Generating 2d meshes works great. But for some reason 3d one can't be generated.<br>
<br>
Would you be so kind to take check the files and tell me where the problem is please?
<br>
<br>
Thank you.<br>
