Hi Pilou,

> So you must have one more line (or 2 clicks) for kill the incertitude :)

Yes, it seems so... But adding 2 clicks creates a new problem of making the UI and workflow for Extrude more complex.

If I can find a way to make one of the existing commands more powerful without adding any additional UI complexity, that is something that I try to jump on and make a high priority. I thought I had one of those situations here but maybe not after all...

But yes maybe the full answer is that it needs more lines drawn in there to define all planar regions better. But then that starts to get away from the benefit of having fewer steps as well.


However, as part of this experiment, I also made an improvement to shell which is definitely nice. Previously when shelling a surface like this:



In the resulting solid you would get multiple pieces along the top, one for each original edge:



Now that is tuned up to combine those fragments that are all coplanar into a single plane:



That is something that was already happening with Boolean union, this is now added for the case of shelling a surface into a solid.
