RE: Adding a new force to a model

Is there an example of an external force (I think its called a torque actuator) that can be created to act at a joint? I wasnt able to find an example of it.

RE: Manually Modifying a jnt file

I am trying to use the manual scaling. However in order to scale the model either up or down, I need to know what the initial values were. And the paper that Dr. Kate Saul has provided only provides length properties for the muscles.

RE: Manually Modifying a jnt file

<t>Thank you Ayman. I will do that. And for the remaining changes it is simpler to do it in the .osim file.<br/> <br/> I had a question relating to the axes of individual components. I have set their visibility to on so that I can see them. I just wanted to know if the axes in the same direction are...
