Help Required: Pattern around arc with constant HORIZONTAL dimension?

Hi Guys,


So I want to parametrically "Pattern" an object around an arc, but the catch is the constant dimension is in the Horizontal or X-Axis not around the arc. See the attached image.

I will later use some equations to alter the number of patterned objects, or change the horizontal dimension based on the Arc Radius, this I can do, but does anyone have an idea how I can build the Arced pattern with a horizontal dim?

Of course SWX has a pattern "around arc" feature but the constant dim is the distance around the arc not the horizontal dim as I desire. You can see the driven dims show that the distance around the arc is greater for each additional item in the "Pattern"

Maybe there is a simple way to do this? But Im really struggling to be honest to find a solution....

Im on SWX 2014

Thanks guys!
