Not closed surface
-
I'm not up on all the technical jargon yet, i.e., coplanar (I'm looking in up in Wiki), but maybe someone can help and get me up to speed...
Here is what I have

I see what looks like a 'crack'... it seems to be only on the top, I don't see it looking from the bottom, but see something inside the face of the hole...

ya, I know nothing is easy, but maybe it can be fixed?
Just printed it and the hole is filled

Third Menu / Hiden Geometry: and you will see that you have only faces closed!

Sketchup has only "polygons" so it must fit faces to segmented curvated surfaces!
Post your file for more investigations!

Maybe from the start you must increase "Number segments of circle"?

Thank you again pilou... because it was caused by my use (miss-use) of VisuHole, I got it from your other post - http://sketchucation.com/forums/viewtopic.php?f=79%26amp;t=65214%26amp;p=598110#p598110
Thank you.
