Hey,
i've got similar problems to giulio. My biggest problem is, that my stl file is not closed and i get pretty bad snapping at the edges.
I tried to repair/clean my stl with Meshlab but without big efforts.

Perhaps you could have a look at my stl. The geometry will be used as a pipe streaming through the big patches.

kanal_original.txt


Greetings

Greetings Phil,

I had a look into your file and here's what I got:
  1. surfaceCheck indicates that there are 8 unconnected regions:
    Code:
    surfaceCheck kanal_original.stl
  2. The reason for this is shown in the attached image, namely that not all vertices are connected to other vertices.
Therefore, it's as good as there are surfaces floating surfaces, when it should be a solid.

As for fixing it... in Meshlab, you can use from the menu "Filters -> Remeshing, Simplification and reconstruction -> Delaunay Triangulation". I wont be a perfect triangulation, but at least it fixes the problem

Best regards,
Bruno

Greetings pizzaspinate,

I think I saw a similar thread of yours on this topic, where you then stated that you managed to fix it. But now I see that you asked this here as well.
Therefore, if you've managed to solve this problem, then please indicate how you fixed it.

If you haven't solved this problem, then please provide more details (namely, if you did any modifications to the dictionary file "surfaceSubsetDict"), since that error message can occur in a lot of situations.

Best regards,
Bruno

Hi Bruno,

yeah I posted it twice because in my experience you don't get much responses when you reply in old threads. Sorry for that.
Yes I managed to fix it. I had to enter the command:
Code:
surfaceSubset surfaceSubsetDict UCAV.stl UCAV_prob.stl
in constant/trisurface to avoid the error.
