oddbarc::getparamatpoint
does this function work? i have a point that is supposed to be on the arc and am trying to get a param for it. it consistently returns einvalidinput.
i implemented some intersection calculation code that takes an arc and breaks it into segments and intersects segments against segments. is it safe assume that im running into errors because this function doesn't have a tolerance for "being on the curve" as im passing an intersection point from a segment that approximates the curve? any suggestions?
