1 closed, degenerate or unsupported object rejected

[Ninfador13]

Hi, I've been tryning to create a region from a 3D polyline, sometimes I manage to do it but other times I can't. The times that I can't create the regions I come up with this error "1 closed, degenerate or unsupported object rejected." With the ones that are parallel to the planes x,y,z=0 I use FLATTEN and the REGION and it works without problems, but with the ones that are not parallel to this planes I can't do this so I don't know what to do. I already checked that everything is well conected and also I remaked the whole thing and it kept happening, it is very frustrating.

 

Any assistance would be greatly appreciated.

It would be helpful if you could post your drawing so we can take a look, but in order for a region to be created, your 3D polyline needs to have all of it's vertices in line. They don't have to all be at the same 'Z' elevation, but they do have to be in line so they will create a flat region.
