Hi all,

I'm having a bit of trouble trying to create a family which is basically a half round window with spokes/mullions that array from a centre. (see attached image)

basically i want the spokes/mullions in both directions to be parametric, I'm happy with working out the math for these but can't for the life of me work out how to get Revit to let me do what I want. Hopefully one of the genius' here can shed some light on it for me

The outward splaying spokes are a simple radial array, it's the arcs that need to be an array to allow for different numbers from the centre, hopefully this can be done

Thanks in advance

Use ref lines to control the arcs.  These can have parameters to control them.

yeah but is there a way of arraying the arcs, so i can add an "arc number" parameter to the family so rather than just having say 3 internal arcs, I may want 5. Obviously each arc will be a different size so a standard array doesn't work. Is there a way to achieve this?
