Hi all,

I've been working with validating Solid geometries in FME. I'm tying to understand the different scenarios and how they translate to the errors FME takes note of.

 

I'm specifically interested in knowing how to cause the issue of "Not Enough Faces" which is documented as an issue in the invalid solid boundaries here: http://docs.safe.com/fme/html/FME_Desktop_Documentation/FME_Transformers/Transformers/geometryvalidator.htm#InvalidSolidBoundaries

 

I performed a simple test where I simply just removed one of the surfaces in the solid, it was just a rectangular prism but now with only 5 surfaces (instead of 6). The resulting error message was "Surface Not Closed".

 

Anyone know where I might expect to see the "Not Enough Faces" pop up?

OK, I found some example where I get this error. A solid with only 2 faces - Ha! I guess the minimum number of faces you need for a valid solid is 4.
