self-intersecting error after very simple extrusion

[elf_monkey]

Please help

After creating an extrusion in SCULPT mode with a very simple sketch, I´m unable to fill a hole in the face of the resulting shape.

I get an conversion error, some surfaces are self intersecting even tough the sketch is very simple and the model quite straightforward

Here a screencast

Thanks

Hi @elf_monkey,

It looks like the screencast didn't make the post.  I think you have to click on "Insert" to get it to actually get inserted (it's not obvious...):

I tough I clicked insert. Lets see if this time.

Thanks

Thanks.  The video made it through.  I'm able to reproduce this.  I'll file a bug.  It looks like "Fill Star", and "Reduced Star" modes for Fill Hole both have this problem.  I did find that "Collapse" will succeed:

Jeff, FWIW: T-splines has failed at this type of fill since its inception (Or at least since I first used it in Rhino many years ago, before AD bought it).  Fixing probably wasn't a high priority because it also produces terrible geometry,  at least from a T-spline centric view.  I've always had to build more T-spline edges and create good geometry to close surfaces like this.
