This is Your Section. Controlling Sectioning in Inventor Drawings.

“Divide your movements into easy-to-do sections. If you fail, divide again.”
Peter Nivio Zarlenga quotes

While on working off site on an assignment, I encountered more section views than I'd seen in a long time.

We all know that there's going to be components that won't be sectioned.  But Inventor doesn't necessarily know which components we want to participate in the section view.

Not what we want, the plunger and shaft shouldn't be sectioned

 So how to we tell Inventor that it shouldn't be sectioned?

This is what we want!

Here's a video on how to control which parts are sectioned in the drawing.  Happy Inventing!
