Revit knows about arc control points - center, ends, points along the circumference, tangency at ends, heck it even lets us draw arcs using these control points. Why can we not constrain enough of these control points to reference planes to reliably define parametric geometry? Why must we use arcane formulas and convoluted contrivances to wrestle these simple geometric shapes with parameters? Do all these formulas slow down a project? I don't know but I do know they slow me down!
Please allow us to simply and predictably align and lock arc ends and a point along curve or center point.
Same thought applies to circles and ellipses.
