Hi Anis,

> Which do you think better comparing export to iges, step or sat ?

Each of these formats has some complexities in slightly different areas, so I would suggest getting as many different formats as possible.

So instead of choosing one between IGES, STEP, and SAT, instead request getting the same model data in each of those formats, including 3DM and Parasolid if they are able to do those.


But if the original data is messy and possibly contains holes and overlaps in it then of course that will not get automatically solved by using some particular file format.

If the original model data is ok then one of the formats that contains solid information (STEP or SAT) will save you some joining work.
