Robot Model Bug

I am trying to model a 7-axes robot (Rethink Robotics Sawyer), but when I set waypoints for the modeled robot, it does not reach them. It seems the root cause is that the robot model is excentrical, meaning the end of the arm is not aligned with the base (see enclosed picture). 

When I take any other 7-axes robot model from the library and change the parameters so the arm is excentrical like Sawyer, the problem with the waypoints is exactly the same.

Thank you for help.

This type of kinematics is not supported in RoboDK at this moment (the main blocking issue is that axis 1 and 3 are not coincident).
