Invisible material for walls, and the vector views

[ambrozac]

I made a wall invisible, not by designating it as such in the wall spec dialog under GENERAL> OPTIONS, but by making its material as INSULATION>Opening (no material).

Vector views show it as opaque white, not invisible.

Is there another material I should be using to make the wall invisible in vector view?

I saw Suggestions first and replied there. I believe you just need to edit your "Opening (no material)", to have a "Gap" material type, rather than what it is now, "Area".
