Hi i fairly new to motion and i have tried to simulate my
linkage in motion using the intelli motion builder but it has not
seemed to work. i have used rotary simulation in solidworks and
that workd but i would like to do the same in cosmos motion so that
i can work out the magnitude of forces generated at the pivot
points.
can anyone help me? a forum member called Ian helped me lasted time but was unsure how he did it.
thanks
Notay

In motion (2007) you have 2 options. You can apply motion to bodies, or to joints. Applying it to bodies is very similar to what you do in Physical simulation etc, the key difference is you need to define a coordinate system to define which direction the motion(s) will act. Apply it to joints is just a matter of right clicking on the joints and editing their properties and clicking on the motion tab to define motion on a specific joint freedom (eg Rotate Z for a revolute joint).
To some extent, this has been made more intuitive in 2008, where you appy motors or actuators the sames as in physical simulation and SW animator. You can only define a motion in one direction, but it realtes more directly to what you would have in the real world than in the form of what the solver takes the information (constrainted motion in specific degrees of freedom between a pair of markers).
I thought you had gone through the tutorials, and that should cover the basics of looking at applying motion and looking at results. Training is really the next step to take the best advantage of the tool.
