Just saw it. But, I don’t see that group in my model! Deleted it long ago. Trying to figure it out now.
So, I just downloaded what I posted and I can’t find that group.
I have all layers turned on and show hidden geomtery.
I tried “unhide all” while editing each group.
Outliner shows only two entities, with nothing under them.
How did you find it?
I downloaded your “no surface borders.skp” file from your post and the tag was there in the file.
It shows up in Outliner, too.

Ok, makes sense. That’s just a back-up I made when first starting the model.
But, I think I’m pretty was still seeing severe clipping issues after deleting that…
Box said there was “something wrong with the model that was causing clipping” . Box, were you referring to the “no surface borders” model or the original “lsu” I posted.
The no surface one.
You mentioned clipping so I commented on how it can occur.
Then I commented on the bad geometry of the circles.
Only after that did I look at the clipping in the other file.

Ok, it must be that group was causing the issue since I can’t reproduce the clipping issue in the later model revisions. Sorry about that digression.
But, am I right in concluding that you can’t count on SI from identifying issues in your model that later will cause surface errors to occur? I’m trying to be very careful when creating geometry and ALWAYS run SI, but still I’m getting into trouble…
SI can’t predict what may happen. Something must have changed from one model to the other. That could be that you moved something that moved something else that caused the bad geometry at that joint to move and cause an error SI could pick up.
It is not infallible and there are some ‘errors’ it cannot find.
So, one last question and I’ll go away for at least a month.
How would you go about fixing that surface error? Please don’t tell me to start over from scratch.
Thinking back, I probably messed the thing up when I was “unrounding” corners to add that snap-on barb.
I keep making the mistake of rounding corners that I have to later undo. I think I always need to save a copy before doing any rounding!
I have a fairly recent “shiny” back up, --I’ll redo the unrounding and later edits. (fool me once, …)
Thanks again for your prompt replies!
Give me a sec.
I’d just remove the offending hole and replace it with the good one. Then use the very hand Fixit 101 to clean up.

Thanks Box!
BTW, I can go to back-up model , export the “shiny model” a component, save, and reload in that model. It stays shiny.
But, if I start a new model and import that component it is missing the front face in that hole area.
I can post if interested, else I’ll move on.
Thanks
Move on.
Explode and regroup it and see if you have the same issue.
Wish I could give you more hearts!
Curious about how you went about modeling these parts. I found a number of weird things about it like faces that wouldn’t show as selected. I also found some odd things related to the choice of coarse Display Precision and Length Snapping. I remodeled the parts and had no issues with clipping, or getting solid components from the beginning. It sounds like Box got you squared away though so I’ll just leave screen shot.
I imported the DXF from Corel and used it to set guidelines for the perimeter of the major rectangles and center locations of the holes.
Pushed through the holes and used Fredo6 round corner on some edges (what I’m printing now has many more rounded edges).
I always work at maximum precision and no length snapping. Can’t say much more than that.
I’m not seeing any of that weird behavior. Maybe you are not working with the model I originally posted? The second model was just a backup I dug up to show the same geometry issue in the hole was in the older model yet SI didn’t complain about it. May have gone back a version from there before getting to what I originally posted.
I would just add I did a lot of scale up by 1000x and back down.
You wouldn’t have to do that with the “Dave Method.”
