I want to model a over molded part. I have the inner base part and the outer over mold part. I want to cut/indent/remove the volume of the inner part from the outer.

What is the easist method? I'm not doing a actual mold design, I just want to show the two parts seperately?

Is the Indent feature used only in a single model? The help gives a example of teh target bode and tool body? This option is not available in Assy mode. I'm confused? Do I need the solid bodies in the same model?

I have a screen shot attached showing the outer/inner part assembled. I want the outer part to have the cavity of the inner volume.
