Boolean doesnt boolean :)
show user profile  GreenFlag
Hi,

I've got difficulties to boolean an imported mesh:
- Pro Boolean Substraction makes my mesh disappear almost completely
- Boolean Substraction makes only a cut into the object but doesnt produce the mesh of the intersection, I get a cut but it is only a hole in there.

I tried:
- to get the both objects to have a similar number of polygons (one is big and the other is small so with similar number of poylgons, I have on 1 side small polys and on the other big polys)
- I am sure they do intersect
- I also tried Reset XForm, nothing really change,

Any other idea?

thanks :)

Cap them both so that they're watertight before booleaning. Think that's about the only trick to it.

As for disappearing faces... not sure, maybe your faces are flipped?

similar sized polys helps

Hi,
thanks for the replies :)
I capped it (took a while, the geometry was not easy to cap),
now the ProBoolean doesnt disappear anymore but still it only cuts the polys and doesnt create the intersection mesh.
It has still here and there few small openings betw. polys which dont connect exactly.. could b the reason..

one thing I dont understand, when I use a standard primitve, then convert it to editPoly and delete 1 polygon to "open" it.
then the boolean still works good, even if the object is "open".

There must still be a difference between my imported mesh and a "good mesh".
I have also used the similar sized polys, my normals are uniform.

Incidentally, when would you say is the best situation in which to actually use Boolean / ProBoolean rather than actually model shapes into geometry?

From my limited and short experience with it, I've found that proboolean will more often than not ruin my geometry.

So I always end up spending countless hours trying to get perfect holes or whatever into a model rather than let boolean do it for me.
Maybe I'm not using it properly.

Flat shapes Like walls, etc.

I prefer shapemerge and manual editing.

Best time = cutting a circles / tubes / spheres into a curved surface... I suppose.

Don't see the real difference between ProBoolean and boolean. Poor results from both, generally.

What I did to resolve the thing:
As the inside part of the boolean was not created and I had only the cut,
I used the shift+drag to create the geometry inside.
