Defect Marks in SubD

I’m modeling in SubD and trying to place a new SubD Edge Loop. Suddenly I’m getting a bunch if these little black dots with white exclamation marks in them and the loop won’t place. Can someone please tell me what I’ve done wrong?
Thanks,
Michael D.

Hi Michael - can you post an example? I believe what you are seeing is that the SubD has gone bad and the markers are showing you where the bad components are.

This is what I’m seeing:

Hello - the dots probably show some secondary text in Properties that tells you what the edge or vertex is that is bad- but I can’t tell any more without a file. See if RepairSubD does anything good here.

Hi Pascal,
I tried RepairSubD. It wound up connecting two previously unconnected curves that formed a new more useless curve and I still can’t insert the SubD edge curve I was trying to place initially. This component seems fine until I try this operation on it. Below is what I see after trying the RepairSubD command:

Hi Pascal,

I figured it out. I had 2 SubD edge loops sitting partially on top of each other. Once I moved one over .010” everything worked again.

Thanks for responding to my query.

Best,
