How to adjust the translation between body geometry and frame? about opensim-creator HOT 2 CLOSED

Thanks. As you suggested, it seems using the offset frame solved the problem.

In my case, the automatically created offset frames when adding the body were sufficient. I moved torso_offset to the desired location of the joint and then moved head_offset so that the skull geometry was in the correct place.

Hi @mohse-n

I think what you're asking is "how can I move the mesh separately from the joint's frame". If that's the case, then the "trick" is to add an additional offset frame to the thing you want to attach to (say, here, the body_offset), followed by attaching the mesh to that offset frame. This gives you a new frame that can be moved independently of (but is kinematically attached to) the original frame.

Steps:

• Right click the frame that you want to attach free-form geometry to
• Click Add Offset Frame
• This will add a new frame into the model that is attached to the frame you right-clicked
• Right click the new offset frame
• Click Add Geometry and select your desired geometry
• This will add geometry that is attached to the new offset frame
• Move the new offset frame

If you find you have mis-attached a frame somewhere, you can usually right-click a frame/geometry then use the Sockets menu to reattach it to something else. The Re-express in new frame checkbox ensures that the reattachment doesn't cause things to jolt around.
