hi gelphyn,

thanks for the detailed reply, sorry i did not see it until now!

that doesnt really address my question… i understand that shapr3d implements things as you describe, but i dont understand why it HAS TO implement it that way.

using your cube example, why can i not use one of the vertical faces (including the 4 edges) in the same way i can use the original sketch(/4 sketches) of the rectangle?

i know i can take those 4 edges and project them onto another construction plane to get back to a sketch, but why do i need those extra steps? the geometry is already there, but for some reason i cant use it!

when you have a more complex shape than a cube this problem becomes more time consuming and annoying.

(i have also run into an issue with the projected sketch where i can’t actually use it: [Can’t fill in gap in generated offset edges](https://discourse.shapr3d.com/t/can-t-fill-in-gap-in-generated-offset-edges/5517))
