Grid object has the following properties:

Name: The name of the grid object
Horizontal, Vertical, Normal: sets the grid dimensions, which define the distance between snap positions. Usually, all three fields are set to the same value. If you wish to enter small values like 0,001, make sure the value of the options/window/metrics tab is set to match.
Color: The base color used for grid drawing.
Highlight: A second color used for drawing the grid lines, whose frequency is determined using the 'Cycle' slider.

Cycle: Defines the density of grid lines that are drawn with the highlight color.
Dynamic: Automatic adjustement of snapping interval.
Dynamic Color: Automatic adjustement of grid color for dynamic grids. The shorter the snap interval, the lighter grid is drawn.

You can activate the desired grid by dragging and dropping it into the view window. This sets the current grid for the view window and activates both 'snap to grid' and 'show grid' options. You can also use view property window's 'Input' tab for controlling view's grid snap and draw options.

	Note
	Do not mix the grid with the ground plane visualization in perspective views. The ground plane has nothing to do with snapping and is provided as an orientation guide only. It is automatically turned off when grid drawing is enabled.

The view control bar allows you to switch snap to grid and show grid options on/off quickly any time.

Draw Grid and Snap to Grid icons

The grid drawing fills the entire view window. If you zoom out the view window so that the grid appears denser and denser, the grid system stops drawing the base colored lines at some point, because the too densely drawn lines would not serve any useful purpose. Drawing only the highlighted lines keeps grid visualization useful. If you continue zooming out, also highlighted lines get too dense and their drawing will be stopped.

The same density control is used when perspective projection is enabled and view camera is not locked to the grid plane. Only the part of the infinite grid plane, which is not too dense, is visualized.

The automatic density control does not affect grid snapping, only grid drawing.

Too dense part of the grid is not drawn in perspective mode
