move origin point but keep axis same orientation in sketchup ?

[DBenz]

Hi,

Sketchup Make 2016.

I simply need to move the origin point, as when working with perspective match the origin on the model must match the origin in the photo. Currently the only way I know how is to use the axis tool but after clicking where the origin should be it expects me to indicate the new red axis then the green axis and the new location hasnt such linear features to do this to. One needs a resite origin point only.

 

Where is this ?
