Hi nameless, these 2 seem very similar:



Do you have an example where it would be useful to have the other variation?

I guess it could be possible to enable it by using grooved + separate height modes and then allowing the thickness here to be 0:



Right now I think it's considering a thickness of 0 to be invalid and so it won't make that. You can set grooved with a 0 groove width which will generate the inner "plug" as a separate object.

The other variation that I could probably allow with thickness = 0 with separate height set and not grooved is to carve off a full width slab like this:


I can take a look at enabling thickness = 0 in v5 once the v5 beta is underway.
