After modeling my house in 3Ds max, i compiled with "Tool model" and while compiling the next message appears:

### WARNING found #4 degenerate triangles.

detail worst-case worst-case
level vertices triangles
--------- ---------- ----------

low 2726 3344
medium 2726 3344
high 2726 3344
superhigh 2726 3344

Strange :S i checked all my model, and all the edges and polygons are in perfect state.
Then i used "Tool collision-geometry" and i got this:

### Casa1_collision.jms
### WARNING found #4 degenerate triangles.
### ERROR edge #209 is open (red).
### ERROR edge #266 is open (red).

WTF?! o.O i checked my house with STL check in 3Ds max, and it says that the model doesn´t have open edges, double face, spikes, etc. Well I imported de .wrl file and the file donpt show me any open edge, it only show 2 stupid lines out of the house :S ¿What the hell that means?

THANKS

select all verts
weld at 0.01
stl check fails.

weld vertx doesn´t work

k
then you have holes in your mesh.
you have max or gmax?

3ds Max

use border selection tool.
drag over entire model.
borders should be where there are holes.
cap them or delete the faces around them and rebuild them.

Nothing is selected with border selection :/ I select all my model, and everything is the same, still not working xD
