PRIMER 22.1

2D Graticule

2 D Graticule

If the grid spacing can is set to 'Auto' PRIMER will calculate a sensible value. If you want you can input a value manually.

With the 2D graticule the space system used to display the model dimension depends on the current view.

Model space

Is used if the view is orthogonal down one of the screen X, Y or Z axes. The appropriate XY, YZ or XZ coordinates are shown, and these move as the model moves (try dynamic translation and you'll see).

Screen space

Is used if the view is not orthogonal. This just shows the current window dimensions (X = 0 - 4095, Y = 0 - 3129). It is only useful for setting up volume clipping using screen space orientation.

If a GRID is added it draws a grid on the screen at the current tick mark interval.
