Thx for the info!

Yes method shawn on Rhino is classic Box Modeling...

You can Make exactly the same with the 4 "rustical" tools given by Max Smirnov inside Moi...
SubDivide, SSplit, SBridge, Sscale sure maybe not so speedy than Blender or special Poly Modeling prog
Here move down the "inset face" is made by a simple "extrude" (not shown on this video)
