dynamic blocks and reverse rotation actions

[cholpuch68]

I am working on a block where I need to illustrate counter-rotating objects... does anyone have an idea on how to apply an independant basepoint rotation action that would allow a clockwise rotation?

Can you post the drawing?

Do you mean that if you rotate one object clockwise, another object rotates counter- clockwise at the same time?

Thats exactmy what I am looking to do. A rotation parameter that rotates sth exactly the same angle as another rotation parameter but in another direction or one parameter that has two acitons one with a negative angle modifier (such a modifier doesnt exist). In other words how to relate values of two rotation parameters... Any ideas for two counter-rotating objects with one grip?

You might try using angular constraints.
