Hi Elaine,

Thanks for the quick reply, it helps a lot.

How can I show the coordinate axis and know the xyz of one exact position which maybe used as my origin for coloring gradient.

Thanks again for your help,

Yanhe

Hi Yanhe,
In Surface Color you would choose coloring by "height" which actually means by distance from a plane along its normal; the plane can be in any orientation. You would just need to enter origin and axis values to define the plane. The default values of these are set to color along map Z (axis 0 0 1). To color along X instead, change axis to 1 0 0 .
I hope this helps,
Elaine
