I largely agree with Justin’s point, but I wish we had more quantitative data to back up the anecdotal evidence we frequently hear. Our conversations with Architects and Designers often confirm their use of tools like Rhino Grasshopper and D5.
This brings up a comparison to my engineering school experience in the early 2000s, where Solidworks and AutoCAD made fillets and chamfers — which are critical for stress reduction (i.e., eliminating sharp points) — a fundamental requirement, even offering tools for variable radii.
I wonder if SketchUp’s nature as a surface modeler restricts the focus on such functions. Features similar to SolidTools and Boolean operations are standard in most other CAD design software.
Finally, a note on our offerings: beyond K-12, we already provide the more functional SketchUp Studio version to universities (Higher Education)
