I tried it but it doesnt seem to work : the snapshot joined shows a trimmed
surface not realy nice. I think there is a "contour line" approched by a
nurbs line. So surfaces are trimed whichever import option I unselect.


Please send us the IGES file with a brief explanation of where it is the
problem to chek it.

I'm sorry but I can't send you this IGES. If it is of any help, it was

Thank you again for your helpfull advices.

Subject: [ GiDlist ] IGES import


Hello everybody,
I would like to know if there is a way not to collapse and trim entities
when
I import IGES files in GID. I tried to unselect the switches "automatic
collapse after import" and "fast collapse-trim" but I get - when I get
ones -
strange surfaces. I played with tolerances too but without any success.
Regards, Olivier Bounhoure

I'm going ro precise what I would like to do : importing the trimed surfaces
without trimming them! I mean importing the base surfaces and the trimming
curves but not to perform the trimming. If GiD can do this, it would be
fantastic to debug such a bad file.

I'm sorry about the .tif file, I can read the original but I can't read the
one I linked... Maybe I can try to link another type of file? Let's try the
postscript.
Regards, Olivier Bounhoure

The option "Collapse after import" try to join coindident points, and trim lines try to divide and join lines coincidents in part.

But this collapse is not related to the concept of trimmed surface. A trimmed surface is a portion of a surface, determined by curves that trim a base surface.
A trimmed surface in the IGES file will always create a trimmed surface in GiD.

Note: the image snapshot.tif is not readable, possibly the file it is corrupt.
Without an example of the problem it is impossible to known it.
