Hi all,
In the attached part file, I’m trying to make an extrusion from “SKETCH Vert Wall”; however I get the error in the attached screenshot when I do so. This is particularly confusing because I made it a point to create the sketch where the edge of this new extrusion doesn’t come in contact with the nearby curved edge of another extrusion.
Anyone have any ideas 
? All help is appreciated!
Thanks in advance,

I did a quick check, it will produce zero thickness geometry because the software is attempting to merge all the bodies (floor and cutarcwall)
Under featurescope, select Select bodies → Uncheck auto-select → Select Floor as the body and you will be able to extrude it normally

Cutarcwall will still remain as a separate bodies in this case
FYI, with the current arc wall design the software will not be able to merge it because it will indeed produce ZTG
