@Aerilius You again misinterpret my comments: “You have the right to believe that the code bases are totally without overlap.” I never did say that. I said they were not exactly the same, to refute your earlier contention they were (“there is still only one code-base of SketchUp and two UIs”). Please do not put words in my mouth.
I do believe it would be a waste of time to try and defend Trimble’s stellar reputation in adding 3D functionality to SketchUp. My guess we would be arguing over a rotated rectangle tool and it’s inherent value to 3D modeling in general.
Your efforts in supporting this community are admirable and I thank you for them.
