Excellent points by @laborda here. I agree with all of it, the most puzzling of all for me is the solid editing of simple prismatic stuff.
SolidEditing is a part of Rhino continues to be completely broken. Even for the simplest of things like planar surfaces and extrusion-type surfaces. Even VC barely-funded and silly iPad modeling-playground apps have solved this.
1.I just tested this problem:

this one reported by me in 2016:
…still broken:
The worse part of this? Rhino doesn’t even have a designed and programmed feedback mechanism routine that at least says: “Sorry I just turned some of your degree-1 and degree-2 surfaces into higher degree and much higher density surfaces. Also your planar surfaces are not longer planar”
