Thank you Frenchy Pilou your script works.Now I see why my objects isn't solid.Now I have more motivation to create new 3d models with moi3d again :)

Best Regards, Nikola aka zenox3d

I had an experience recently wherein a joined surface would not seal to a solid, but also did not show any naked edges.
I tried everything I could think of... scaling up 100x, Separate and Join again, etc.

Eventually, I gave up for a while. When I returned and opened the model again, voila, it was a solid.
This has happened one other time. I just saved and reopened the model to have the solid complete.

Just out of curiosity.
what is a naked edge? :)

Quite new with MoI and did not find this in help file.
Thanks

edges who are not connected to something for build a surface!
generally very small distance between vertices

Hi Mr. Yuri - a "naked edge" is an open edge that is not joined between 2 surfaces.

A solid like a box has no naked edges - every edge of the box is a spot where 2 surfaces meet up.

If you create a plane surface for example that will have naked edges at its boundaries since it is not connected to another surface there.

If you're trying to make a solid you can't have any naked edges and that script above is a good way to see where they are at, those will basically be openings in the "skin" of your object that is preventing it from being watertight.

Thanks.
Made a note for the script ;)
