Topo subregions are created below main topo surface

I've added a number of subregions to a topo with no problem and then I noticed today that all new subregions appear at sea level. There does not seem to be any way to move them up to where they below? Survey point and project base point are both 0,0,0

Is this a feature or a bug?

Got to ask: Are you sure those are Sub Regions?

Yes they are indeed. I actually figured this one out - you have to delete the "hole" boundary in the outer subregion and then add the inner material's subregion on top. So you have a small circle on top of a big circle instead of a small circle on top of a donut so to speak.

Sorry, to ping you again, but it isn't possible to displace SRs the way you are showing. You sure they aren't Split Surfaces?

Nope definitely subregions - see attached.

 

If you edit the dark gray patch and delete the inner large rectangle, the red subregion will return to the surface. What's odd is that the smaller rectangular patches don't have the same problem.

I've never seen anything like this. It defies logic.  I'd report it.  I'd be curious to hear what Autodesk has to say about it.

Is there a fix to this problem? My subregions are showing up around 100' above the topo I am cutting them out of.

Sub Region? That's not possible.  Sounds like you offset a Split Surface by accident.

What a weird quirk. Thanks for sharing your findings (again), @roothcad

My fix was to use the Graded Region tool to "create a new toposurface exactly like this one" and delete the old one, and the subregions worked as expected again.
