Contour lines between zones?

Hello community!

I was wondering if there is a way to see lines between zones when they are attached to one another. I am making some feasability studies with gross amounts of m² so no walls or anything else is necessery for now but when zones are adjecent to one another they dont show any line between them rendering as one big volume. the only solution I see so far is to make them smaller so I add a seperation between the two. Though that does work for different zones in different floors, it would render the purpose of showing gross m² on a plan view innacurate and therefore I have to work with net amounts but that is not convenient for this phase of the project.

Any ideas?

EDIT: I just also noticed that if I use a different surface on a zone a contour will appear. It solves the problem somewhat but its a suboptimal solution if I want to keep the same colour

Hi,

Wouldn't enabling a floor plan contour line help? Of course you'd have it on the entire perimeter of the zones.

To my knowledge you can only edit the behavior of adjacent slabs, in model view options. Maybe for your purposes you can switch to using slabs for massing (if that is what you're currently doing). You can also schedule those, grab their volume, color-code, etc.

You can use identical copies of the surface material. Same appearence, but visible contours.

And this one... 🤓

Edit: probably not valid in 3D 🙂

Graphic Overrides don't even help to force these lines to show.

Hi @AlexKW

If you want to see the separation between zones in a 3D view you could use a transparent surface for zones or redraw the contour lines with the Morph tool using Geometry Method: Polygonal.
