Multiple Fixed Pivot Points?

[WiZeR]

Hi Guys

I am designing something that needs to have multiple pivot points, much like a scissor arm. To allow me to see it actually moving before building it, I'd like to be able to connect all of the pivot points and then see how each pivot point effects the movement.

After some research, I found SketchyPhysics, which seems to do most of what I want. But it does not allow me to use the pivot/hinge points to physically align objects in the model. i.e if I click 'play', I can see the movement, but when I click stop, the objects return to their original position. It would really help speed up the process if I could permanently attach various points, so that when I move one point, the others stay together and move with the rest of the arms.

Perhaps a pic would help:

Is there a way to do what I need? Or am I stick with moving each component piece of the model bit by bit?
