how do you section?

The easiest way that I know of is to have a plane at that location and tell it 0" offset from that plane. You can get it to reference that plane by preselecting it.

So if you want the middle, then it makes sense to follow my oft-spoken suggestion to always use midplane extrudes, symmetry, etc. unless there is some specific reason that you want something other than that - make your default method symmetrical. That way you will have the system planes in the middle of stuff and may use them later.

Thanks Wayne!

Another way to do it is to RMB on the section line after placement and edit the sketch then add relations to the line to secure it exactly where you want.
