Solid vs Joined Surfaces

Okay all you MoI geniuses...I need some advice, please.
Here is another formed plastic model I'm working on. It looks like a fairly clean (except for where I cut and stretched the bottom part) solid part. MoI and Rhino both tell me it isn't.
I constructed the outer surfaces from two sections, then joined them with a blend. Then I offset the resulting surface to a thickness of .040".
Can someone take a look and tell me what bad edges or other problems they see? I can use this for what I am doing, but I want to learn to make my models 100% correct.
Thanks!
Ron

Hi Ron, there appears to be one area where there's a missing surface so there's a hole there and also it looks like the neighboring surface to that area may be a doubled-up stacked surface (2 copies of a surface duplicated in place with some of their edges joined):






To find these areas I used the "Select naked edges" script which I recommend that you set up as a shortcut on your N key so that you can just push N and see which specific areas of the model are not joined together, see here for the script:

That's the main thing you want to use in MoI to help guide you to problem spots. Then you need to zoom in on those areas and take a close look, the "Zoom area" tool on the bottom viewport toolbar can help with that since you can snap the center point for the zoom onto the particular point you want to examine and then drag out a bit of a rectangle for it, and when it has zoomed there that snapped point will also become the rotation pivot point so you can orbit around in the 3D view a bit to examine that area.

Fantastic, Michael. Thank you for the quick feedback.
I was meaning to check out that script, but wasn't sure if it was for me or not. Obviously, it is!
Love this forum!
Ron
