What is this called again?

[SteveFrey]

I've done this before as a part of an assembly but I forget what it's called and more important, how to do it (see attached).  Occasionally I need to show a small section of an assembly in my drawing (see attached).  I did this one by doing a SAVE COPY AS of the assembly and then just creating a 2D sketch around and extruding through the portion I don't want to show.  Then I just import it as another assembly in the position that depicts it best.  

I believe this can be done as part of the original assembly and be toggled on & off in the drawing (or am I imagining this?).  What's this called?  More importantly, how do I create it.

Is that a break out?

You will need to create a 2D sketch inside one of your views, to then use a CLOSED loop from it for your break out:

Can you just place the main assy off to the side of the drawing and then use a detail view with smooth edges and view label turned off if need be? That way you don't need to create a bunch of extra stuff in the assy. Just a thought.

You could also just place in the assy view and then crop it:

I don't think it's a break out view.  I never had much luck with them.  Will a break out view be able to give me the full 3D view like I have in the top left corner of my pdf?

Can I make that into an isometric view like I have in my pdf?

Looks like I can.  I think that works.

Or I guess do a save as of the assy with a specific name such as "cut away" that way any changes made to the parts would reflect in both assemblies? Drawback: 2 assy's to maintain??
