non-planar quads inset?

[rv1974]

I just can't find the subject in any of Thomthom tools (vertex, subd, quad face).
Is it really still absent?

Hello,
It's been a while since you posted here, but maybe you'll find my response useful.
Indeed, there is no inset tool designed for non-planar quads.
Here's some workaround:

You can also take a look at Tools On Surface by Fredo. It has a tool called Offset On Surface. It will do half the job, but you'll still have to merge excess vertices manually.
