Hey guys,

I am working on a solidworks motion study of a car with a scissor mechanism on top.

This scissor mechanism has to go up, pick a box up and then come down again.

After that the car drives over different obstacles.

To animate the scissor mechanism I have to make it flexible first,
and then I start the motion analysis. 
What happens is that the scissor mechanism filps underneath the car and wont come up.

(see the pictures; 1 picture is the car normally and 1 is with the mechanism flipped).

What can I do to prevent this?
