Dear all,

Is it possible to modify a model in OpensSim GUI e.g. change contact forces values in Tug_of_War example?

If not, this would be a nice feature to have in the future.

Hi,

My experience with GUI would be good for positioning or scaling models. Also, marker tool is good for identify location on ground or any local frames. But if you are willing to create new body or new items, I recommend to edit osim file directly through XML editors.
Modification works were back and forth between GUI and XML editor. It's not easy, but you may have better understandings through these works.

Thank you,

Hi,

Force values are "computed" based on the properties of the "Contact Force" and "Contact Geometry". The GUI allows you to change these properties and to modify/move geometry used so new values are computed when you run a simulation. If you need to add/remove objects/forces/bodies/etc. from am model then likely you'd need to edit the XML files that have the model definition (.osim)

Hope this helps,
