What speedy method(s) can be used for make the same in Moi3D ?
On 5 sides (side bottom is not necessary) and same unity on each sides (say 1 )

Grooves on lines (or faces) selected... function Inset don't give exactly the same result...
but surrerely can be used for some steps...
Ideal will be draw lines then Gooves are made ! :)

Of course for some lines in the same time because one by one is some painful ;)



Some beginning ideas.. but here only one line! :)
(not moved of 1 for more visible groove)
Boolean Diff, Offset, PolyLines, Extrude, Boolean Union
