Faces appear unwanted in Z-suite

Z-SUITE/Firmware Troubleshooting
#1
In the Z-Suite software, as regards this piece attached in the image, were generated faces do not want.
How did you generate these faces?
Attached is also a jpeg of how it is done the piece without the faces generated by Z-Suite.
Thanks!

I'd check your mesh in NetFabb or something. Every time I've had a problem like this in Z-Suite, it ended up being a problem with my mesh. Maybe not the case here but worth a shot.

Funny, when I first read "Faces appear unwanted in Z-Suite" I had this image in my head of Rafal's face suddenly appearing on the screen  :lol:

I'd be willing to bet quite a large sum that your mesh is the culprit (note the bizarre triangular patterns). Everybody here loves netfabb, but I've had meshmixer fix meshes that even netfabb wouldn't touch.

I definitely got a mental image of a 3d face being added onto the part.  :D
