Issues with missing self-intersection detection between two walls

[jiushi-ai]

Hello,

I've also discovered an issue: Meshinspector seems to miss some self-intersections.

I've encountered similar issues in several models I've tested.

Here's a specific example:
I fixed a model using Meshinspector, exported it, and then used Magic RP to detect self-intersections (it appears to be two spatial self-intersections, with two sets of faces slightly intersecting each other).

However, Meshinspector didn't detect them (even with touchIsIntersection = true, it didn't detect this type of self-intersection). They only slightly touch each other spatially, like a burr on one wall touching the outer shell of the other.

See the image below:

The email provided a test STL file. I isolated the self-intersecting faces detected by Magic RP and exported them separately.

Hello!

I just tried to reproduce the issue with the files you've sent on our support email and could not reproduce it:

There could be some confusion because in Mesh Healer we only detect self-intersections within single component and do not detect intersections among different components.

You can verify it on Select/Select Self Intersections tool
