Closed kinematic system assembly error (SimMechanics Second Generation)

Hi,
I am modeling in SimMechanics Second Generation a closed kinematic system. Due to the fact, that the positioning of the bodies is always relativ to the connected base body, I am struggling with an assembly error that is caused by inaccuracies of several rotations and translations. The systems looks like this: World Frame - Body 1 - Joint 1 - Body 2 - Joint 2 - Body 3 - World Frame
If I open the system like do not connect Body 3 to the World Frame it works!!
Any idea how to do a more accurate positioning or how to solve this problem?
Thank you very much for your help in advance!
Regards Chris

I had the same problem and solved it by looking concentrated at the coordinate systems for hours. Then I changed a single digit and then it worked!
The model report could really provide more info about which joint does not fit in which axis...
