Hi, I am back again already, sorry!

I am trying to use wrap solidify to strip the skull of a CT and I am getting this error:  
“Wrap Solidify failed. Mesh has become empty during shrink-wrap iterations.”

I saw a post on the forums about this error from three years ago, but the answer then was to make sure they were using the stable version. As far as I know, I am already doing that. (version 5.2.2)

Anything else that might resolve this error? Again, I am incredibly grateful for any answers, Steve Pieper has already saved my butt once.

Oh! I forgot to say, I was following the 3d Slicer segmentation recipes. Using the extensions SurfaceWrapSolidify and SegmentEditorExtraEffects.

Oh my god, ignore me. I figured it out. It was my bad, entirely. I’m an idiot. 🙂

Hi, I must be making the same mistake, but I am not smart enough to figure out what I am doing wrong. I am getting this error on 5 out of 20 scans. Any advice?

You can’t be doing what I did, I felt phenomenally stupid. It had already completed the task. I just thought it hadn’t because it doesn’t gray out the option so I kept clicking the button!

You can enable “Save intermediate results” option to see what goes wrong during the iterations.
