Sketch looks fine, but when run through slicer faces disappear

[kruuth]

I build a shape in sketchup and looks fine in sketchup. I dropped it into slicer and when I slice, faces disappear. Did I miss a connection to a face or something?

Your model has some backface facing outwards (gray), rightclick over a white face and choose to orient faces. After removing one internal face and grouping, it should be a solid (see entitiy info) and ready to print…

Found the internal face. Thank you for the help.
