Hello
I don't have access to ANSYS but I want to understand how an arc is defined with LARC.
The 3rd keypoint (PC), I assume lies in the plane of the arc, that makes sense. But it also has another function which seems to be to determine which one of the 4 possible arcs of the specified radius between the other two points to use. Can anyone explain how that decision is made? All I can find is this. Confusing part highlighted:
"Keypoint defining plane of arc and [highlight #FCE94F]center of curvature side (with positive radius)[/highlight]. Must not lie along the straight line from P1 to P2. PC need not be at the center of curvature."
