Unlock and edit Simulink toolboxes

Hello,

I am using the Aerospace Toolbox 6 DoF toolbox (https://www.mathworks.com/help/aeroblks/6dof-1.html). I want to edit the link subsystems in the toolbox but Matlab displays an error:

Attempt to modify link 'TESTING_quartasb6Dof/6DOF (Quaternion)'. You cannot modify this link because it is either locked or inside another locked link.

Is there a way to safely unlock these subsystems for editing OR copy over the entire set of subsystems and then unlock them for editing ?

Thanks,

Mike

Like your last option is the safest. I don't have the Aerospace Toolbox but if you are able to see the contents of the subsytem. First copy that subsytem from the toolbox paste it. Unlock it , break the link and start editing. https://www.mathworks.com/help/simulink/ug/creating-and-working-with-linked-blocks.html again I don"t have the toolbox so do it if the block allows you to modify the instance of the copied subsytem.
