How to reposition the "endpoints" on a dimension

Sometimes I need to re-position a dimension, like if one of the endpoints did not snap to the right location, or if I want to change the object it is snapped to.  However, I can't seem to find a way to move the endpoint node.

thanks

  • Dimensions connected to an object are just that; connected to the object.
    I don't think you can reposition it afterwards without breaking it apart, and if you do it stops being a dimension object.

    Maybe you can try creating the object "floating" first, and then make it snap to the object?
    It will not be connected to the object though, and won't scale with it for example.
