how to draw 2D figure , for example a circle, in the screen, no the in 3D screen

[aaaa]

The Vizard 4.0 Documentation has no introduction of the function of 'vizshape.addCircle', how could I find these functions? Is there other document I can refer to?

Thanks for mentioning that, we need to update the vizshape docs. You'll find most of the commands documented there.
