From now on, the X- and Y-coordinates of all other points you define will be based on the new reference point.

Query function

Reference point ( Enter for centre of page)

Specifying point by clicking on screen

X-,Y-coordinates for this point

By default, the reference point has the coordinates of (X = 0, Y = 0). You may also assign specific coordinates to it, e.g. (X = 10000, Y = 15000).
By default, the rotation is 0 degrees (or radian). However, you may also enter another angle in order to take into account the difference between north and the verticals for surveying.

Move active drawing as well?

By default, the drawing is not moved as well. In other words, existing objects remain at the same position on the screen. However, the INFORMATION > COORDINATES OF POINT function will display other coordinates after you change the reference point.
If you respond to this query with "Y", the contents of the screen will be moved to a new screen position so that the INFORMATION > COORDINATES OF POINT feature will still display the same coordinates as before after the change in reference point. This option is especially significant for surveying.
