Grid Axes and the Current Grid Plane
The coordinates of all nodes are stored in global axes; this is reflected in the nodal properties pane. However, they are displayed and edited in the axes of the current grid plane in the nodal table. The default current grid is the global grid plane (which refers to global axes and has the elevation set to zero).
The current grid is set on the Status bar.
The coordinates displayed in the status bar for a Graphic View are displayed in the axes of the current grid (and also in global axes where these differ). Details of the use of the current grid in Graphic Views is given in the Working with Graphic Views, Current Grid documentation.
The current grid axes can be Cartesian, cylindrical or spherical.
The term grid axes is sometimes used to refer to the xy axes of the grid plane. Since the grid plane is planar there is no z component, though the z direction may be taken as being orthogonal to the x and y.
The term grid coordinates refers to the 2D (x and y) coordinates in a grid plane.
