Making glass see through

[QualicoreHomes]

Hello, 

Not sure if this possible but I am trying to show how far a roof has to be removed for a renovation job.  I thought to use a vector camera view and add some notes overtop in the layout.  I am trying to place a piece of glass at the point where they have to stop removing the existing roof.  I have the same material as the windows of the house which are see through but the separate piece of glass remains color filled.  Is it possible to make it see through? I just want to have the outside lines showing.

Thanks for any help!

I searched "Glass Vector View" but have to admit didn't look close enough .  When I searched vector clear I came across the tread "Can a Material Be Nothing?" where you wrote about making a new symbol without a panel which sent me in the right direction.  I ended up making a symbol so it looks like it is glass.  Thanks for the help!!

Not sure what you're after. Guessing it's an addition? in which case perhaps a 3D reference view with some creative layer settings. Here made the addition Glass house and referenced the as built set to standard. On the addition plan the first shows only walls and roof, second shows only attic walls and roof, third only attic walls.

Another option would be to use the "Cross Section Slider".

Yes it is an addition but part of the overhang has to remain so I was looking for a way to illustrate that in the demolition plan.  Thanks for the replies Mark and Joe!
