Can I set origin to negative coordinates?

[Photon]

I want to start my plan from negative coordinates so that my plan is centered at origin, because when I export and import in DAZ3D, I have to shift my model by about 300-1000 coordinate points. Any help is appreciated.

You could enlarge your plan by dragging an object towards the top left corner.
You may also create a dummy wall by entering negative coordinates after pressing the <Enter> key.
