API CreateCircularSketchStepAndRepeat parameters ?

Did anyone guess how to compute the "arcRadius" and "arcAngle" parameters ?
They look like a polar position of the center relative to something ...
Thanks!

 

Looks like it uses center of bounding box. Would have been a nice mention
SW!!!
From there you can use the coordinates to calculate your desired Radius and
Angle

Thanks Corey...If you're right, it's worse than I expected, not to say
unusable.
(How do you obtain the center of the bounding box of a selection done
through API ???)
I think I'll code my own circular pattern (I pattern gear teeth around the
origin) ...

 

Philippe,

If they had a call available to get the bounding box of a sketch it would be
great but I know of no such thing. I had tested it manually but don't even
want to think about the API needed to get the bounding box. I guess you
could grab all the selected lines and arcs and calculate the coordinates of
their quadrants and keep the largest and smallest numbers and combine them
for a bounding box. Splines would pose another problem though.

Why don't you use a single tooth, and us the pattern feature. It would
probably be quite a bit more friendly than patterning the sketch.
