Problem with uniting volumes
 
1 Attachment(s)
Dear all,
I have got a problem with uniting two volumes (using Gambit) which I generated via “Sweep Faces” (see pic). If I try to unite them I always get an error message: “ACIS error 8030: inconsistent face-body relationships”.
Is there any way how I can avoid this? Thanks a million in advance!
WBR

can you provide your dbs file? (delete the mesh)

Same problem in uniting volumes
 
Hi all,
I am facing a similar problem while uniting the volumes(in gambit) that are previously subtracted. The error message shows "ACIS error 8030: inconsistent face-body relationships".

I want to unite all the volumes(all blades,volumes above and below the blades) and subtract it from another bigger volume(not in picture)

Kindly help me to fix the issue....Thanx in advance :)

be sure your volumes are fully intersected together.
you can unite volumes, one by one, and check which is giving you trouble

Thanx for the suggestion once again.

The blades in my previous post were touching the top and bottom volumes. This time I extended them so that blades and the other two volumes intersect(uniting will anyway make them into one single volume). But even this time i got the same error message "ACIS error 8030: inconsistent face-body relationships".

Another way: As i said there is another bigger volume which subtracts this entire geometry(after uniting). When I tried to first subtract just blades from this bigger volume was successful. But again while uniting resulted volume with top and bottom volumes, error appeared "ACIS error 8033: decision to delete intersection graph was incorrect".

Please kindly help me. Thanx :)

Subtracting volumes
 
Hi, did you figure out how to fix the problem? I am getting

"ACIS error 8033: decision to delete intersection graphs was incorrect"
when I try to subtract volumes in gambit.
