Ground Plane work position

[rhankc]

When constructing building models, I typically let the ground plane in SU equal roughly the floor elevation. I see there is only minor visibility situations when drawing below the work plane, therefore I am wondering is it better to leave as is and draw below the work plane, or turn all elements on and lift the entire drawing above the plane, or is there a 'move ground plane down' selection in SU somewhere?
TIA

Just move the axis to a lower elevation and there you go.

I typically run into visibility problems if I draw stuff below the ground plane so I would suggest moving it up. That is just me though.

I would recommend the same as Eric.

I actually move my model to it's real life elevation height. for instance... if the home's finished floor level is 2200feet above sea level, then that is where I move my model... then when importing into Google Earth or exporting your topo from Google Earth you end up right in the area that it should be.
