How to Draw an Arc which is 1/4 of a circle?

[Johannes]

Is there a way to draw an arc which is 1/4 of a circle?
It looks like Shapes.addcurve only draw bezier curve, but how do I make the
curve a 1/4 of a circle?

I also tried Shapes.BuildFreeForm().AddNodes(), but I couldn't get it to
draw 1/4 of a circle.

There's a quarter-circle in the Basic Shapes set. Hold down the shift key
while you draw it.
