Gray area on design
-
Good Morning, all...
I have a pattern that has a small gray area while the rest of the pattern is white. Running the Solid Director does not indicate a problem, but converting to .stl and opening in Netfabb or MinMagics shows the gray area as an error. I apparently need to correct the problem to generate a clean .stl file for 3D printing. What is SketchUp trying to tell me? Thanks -
Without the model or at least an image, it is difficult to say. My guess is that you have a reversed face there. Is it possible what you are describing as gray is blue-gray back face color?
-
Good Evening, Dave...attached is an example of the area(s) in question. Would like to be able to resolve the error before it goes out for 3D printing. None of the blue-gray areas raise error messages when using SketchUp plugins. However, when written out to .STL format they indicate an error in MinMagics or Netfabb. ThanksBlue-Gray area in question

Indeed. It is as I guessed. The blue-gray faces are reversed. You can quickly repair that by right clicking on one of the white faces and choosing Orient Faces.

Bob, I meant to add the following.
Some folks find it difficult to see the difference between the blue-gray back face color and the shaded white/gray face of front faces that aren't facing the camera. If that causes you difficulty, you might change the back face color to something else that is more easily recognized. My default style has the back color set to a green color that I would be unlikely to use intentionally. This makes it easy to quickly detect and correct reversed faces as well as holes. A missing face would give you a view to inside the component. In most cases you probably don't want to see inside, though.

Thank You, Dave...worked perfectly. It took all of a split second to correct. Maybe I should actually buy that "SketchUp for Dummies"? Regards..Bob

If I can stick my big fat nose in here with this unverified factoid:
The SU/OpenGL default shading for the "away from camera" faces is either called Gouraud shading or Gooch shading intended for basic modeling to give visual cues on the geometry.

I thought you had a nice, cute little button nose.
Thanks for that info.

Naw, but I might have beady little eyes.
