I don't think the inset command gets the love it should. For me, the nomenclature just didn't "speak" to me, or "make perfect sense...

So, for me, it may be adding a second tick.

To me, "inset" would be "how deep the slab carved off. (No border preserved)

Then a tick for border thickness adds the outer border, at some thickness.

Then groove, changes the slab removal, into a groove removal.

Then "use separate height" would add a second depth to the "slab part", separate from the groove part...

I think i really just need to spend an hour on the inset command, to wrap my head around it and its setup better....

So i just revisited the inset command with regards to what i just said.

So the initial inset and value, just combines both the depth and border as a single value.

Then use separate height adds the separation between the 2.

The grove value uses to 2 separated just like the first choice, but loses the initial "slab depth" value, and ability to separate that out... the grove is controlled by the separate height and groove values. The initial thickness value is missing

And what a complexity when it's applyed to just adjacent faces! Internal / external! :)

Hi Michael, the inset trick works perfectly, just simple and easy. Thank you all.

And what's great is the opposite result with a negative value in the height field. An easy way to extrude some tricky faces of a solid.

""""""""" the opposite result with a negative value in the height field"""""""""""

There is also an inwards/outwards toggle in the command.

And when you choose outwards, a different field activates called "Expand".....

Made a quick doodle with Offset.... Just dropping this here...
