how to reduce size of a model
(OP)
I just got a 3d model of an outboard engine, that was sized 11mb in rhino, and imported it in cati through iges, and the size of the model in catia is 44mb!!!!! that is huge.
Does anyone know how to reduce that. The main problem is that the model contains hundreds, not to say thousands, of surfaces, and when you pas over the part on the assembly, it takes a while seleting and deselecting all the part with it surfaces....

He's working with an IGES. What will happen is it will delete everything.

Another trick to keeping model size down is when working with surfaces is to copy the final surface that you want and paste special as result then blow away everything before that pasted surface.

The reason Delete Useless Elements is bad with IGES is this: Useless Elements are elements that aren't associated to a Body. As such, anything isolated in an Open Body (or Geometric Set) gets blown away.
ANOTHER trick for file size is to clean the model (via CATDUA in utilities). You have to be careful with this one because it also deletes things, and you have to make sure you clean with whatever licences the part/product was built with (don't clean a tubing run without the tubing licence, for example).
