Hi All

I've seeing strange results in the export to STL preview, not sure if it's a real problem for just a break up in graphics, using OSX beta.





Notice the 3 leaves on the left are not showing triangles? , the left side was made by mirroring the right side. I delete the whole left side, re-mirrored it same results.



here is how it looks in meshlabs


Cheers, Steve
