flipping

Hi,

in the attaced definition, I use a 2dim slider to position (rotate around a single point) multiple objects. The problem is that doing this causes the construction plane to flip 90 degrees back and forth at certain input values.

This is easily seen when there are 6 arms ('arm' slider at 2) but also happens with 4 and 8 arms - you can see the seam of the cylinder hopping back and forth while sliding the 2dim slider.

What is causing this, and more importantly, how do I get around this?

thanks!
