problem with import geometry from catia
hi all

i try to import a geometry (body + fin) from catia to designmodeler
the problem is that the designmodeler recognizes the geometry as two seperate bodies and when i use the boolean unite nothing is changed (a small yellow true marker before boolean appear - ansys 13.0)
i draw the enclosure and then use boolean substract and i receive the following error message:
Error: operation would result in non-manifold bodies
context: Geometry engine, while generating feature Boolean20

i read all topics about importing geometry from catia and i am sure that the problem is related to the initial geometry file in catia.
my question is:
How i must draw a body + fin in catia to be recognized as one body in designmodeler?
i tried a lot of solution, i changed the type of the file (iges,catpart), iverified the connection between body and fin.... No result

please help me if anyone have trying to import geometry from catia

i guess you are trying to perform a boolean operation between solid and surface...
can you share some picture see what it looks like ?
