Unify the extruded bodies

[ftorabi]

Hi Everybody

I am using Creo 2 , I am quite new in it.

I would like to know, when I extrud a body that interferes into another existing body, are they unified or seen as two separate solids ? and is there an option to distinguish between these two ?

Thank you

If you are extruding a solid body (not a surface) and it intersects another solid body, they become a single entity and you can't separate them. 

If you need to model intersecting entities that need to remain separate, you may want to use surfacing.  Solid is set by default when extruding.

And just to expand a little more on what Matthew said, Creo does not create multi-body parts like NX.

A part represents a single body. To have multiple bodies, you create an assembly and add the parts to it.
