You can see the difference with the capture algorithm vs your box modeller. The capture program creates a vast number of equal sized triangles, where (what appears to be) Sketchup makes parsiminous use of NURBs or n-gons. I don't know how you translate one to the other. Are those curved sides faceted or defined by the edge's curve?

It reminds me of my own effort. I see it was upped 2 months ago. I should embellish it a little.
