@nokipaike: Nice and familiar to me, one thing that really stands out from this is the need for “holes” in mesh surfaces. We have this with 2D curves, any closed curve inside another closed curve is a hole by default. We really need this ability in mesh surfaces as a matter of urgency. I assume that as we already have this with curves, it is not going to be difficult, or time consuming to implement. Can we hear from the devs (maybe @mano-wii ?) on this matter please? It would be useful to get their impression of the work involved.
At the moment, we have to break up surfaces into parts with the hole straddling two faces, this is not good when you want to use wireframe modifiers to get a line drawing.
