I am just trying to use Simplify3D (coming from using the Cube Software) and I am having trouble with some of my parts
When I print them on the cube they work fine, but when I load them in Simplify and view the print preview it shows some areas of the outer wall missing, when I guess it thinks it was to thin?? But it doesn't do that in the Cube Software
So my question - is there anyway to tell the settings to preserve the outer wall? So that the outside perimeter prints 100% with no missing bits?
The picture below is the part, its a face and has eye holes, but not open on the side like it is

Any advise would be appreciated
Regards
Julie
