Thank you Michael.
Interactive creation of two arcs and their intersection is very easy in MoI.
Doing so by Script has been hard, about 50 lines of code, that still doesn't quite work.

Successfully created two arcs, using Frame, Startpoint(s), and angle.
Created one object list by: var arc1List = arcFactory1.calculate();
Created second object by: var arc2List = arcFactory2.calculate();

How is it possible to combine the two lists into one list, with the two arcs in it?

Or create one list in some other script way?

I do not understand the difference between an Object, and the Object List created by
a factory.calculate();

(I need the object list, in order to run intersect script, non-interactively. Then I think the point created can be pushed into the control point array for a curve factory.)
(All this just to find one point.)

(I tried a bunch of permutations, but kept getting type mismatch errors.)

Thank You.
