Re: Elevating polylines
I'm using polylines to draw the electric wiring, plumbing floorheating and ventilation tubes for all stories (3) of the house. This is all put in concrete, so ye, hidden in the floors/ceilings.
I already have groups of levels for each story including base plans and wall levels.

I want all the levels in a specific order so all seems a bit logical. for a specific story the floorheating is in the floor but ventilation and electric are in the ceiling.

Yes, I know that most if it can be done by setting level elevation but you can envison that that you may have two or 3 layers of electric wiring for example in the ceiling, and creating 3 levels for them seems a bit overkill. By allowing the polylines to have an elevation by themselves I can group all wiring for a single floor together to limit the number of levels.

Dealing with levels to make them viewable or not involves lots of mouse work. And again at render time you still have to calculate the position of a polyline so it is not a world problem to include an additional attribute per polyline...
