[Support] Draw a family with a radius (similar to model in-place with sweep)

[Marcus.Isacsson]

Hi fellas!

How would you create a 3D-family that is 'drawable' as a spline? (similar to model in-place with a sweep)
We want to draw it in plan views with a radius.

This is what we're aiming to produce:

I don't get what the challenge is. Revit is perfectly capable of drawing arcs.  You're not talking about modeling that  ornate grid; are you?  That would be near impossible. 

FWIW:

When the family is placed we want to control the straight lines and radius in plan view (as a spline).
Some parts are straight, some are with a radius - All connected. 

Placed like this

BTW: looks like a bunch of rectangular grates formed in an arc.  Use the method in attached RFA.

There is an important distinction to make between splines and straight and curved segments. A spline is a continuously curved line with no perfectly straight sections (even though they may appear straight du to extremely placed grips).

If your use case involves prefabrication of paver elements versus and on site continuous form work to cast in place, it would be important to orient your modelling solution to take that into account. 

Could you clarify that the design and execution intent is really a continuously curved element without connected perfectly straight segments?

I would use walls or railing to model paver. Railing can adapt to floor or topo slopes so it is a bonus.
