Show line at intersection of two forms

[washhh]

Hello Everyone, 

I'm using AC24 and i would like to see line between tow connected 3d element. For exemple tow wall. 

See the image joined 

Thank you in advance

1) In the wall settings dialogue - model panel - override the desired face surface material for the two walls.

2) From options menu - Element Attributes choose Surfaces then duplicate that face material ( only duplication with the same properties).

3) Change the Uncut Line Pen color from Floor plan and Section for only one wall.

hope that helps.

Another solution without overriding the surface material is to duplicate ( building material and the related surface ) with the same properties then assign this duplicated building material with duplicated surface to one wall.

Or place each wall into different layer with different intersection level number.

I see your solution is effective in plan while mine is effective in 3D, Elev. & Sec. that’s cool, but the question is why and when we need this separator line?
