Hello, I'm looking for solutions to simplify assemblies (to send a model of our machine without giving our Know-how and to reduce the size of the model in step format).

How is it possible to erase the holes and/or to erase the small objects and to fill the fre areas?

It is impossible or much too long to open part after part and to erase the holes.

We want to send only one file fused, like molding the external shape of our machine, without the small faces of a prepared model for calculation (I don't know the english word for that).

Thanks in advance for your ideas or advices.
