When entering new nodes or entering a polygon or polyline in plan view, it is often useful to have the coordinates snap to a uniform grid. This allows accurate placement of the objects when the desired coordinates are even multiples of some number.
A drawing grid options are accessed by selected the Drawing Grid item in the Display Options Dialog.
The Grid Spacing edit field specifies the spacing of the grid nodes and grid lines in the drawing grid. The Grid color window specifies the color that is used to display the drawing grid in the Graphics Window.
If the Snap to grid option is selected, all new vertices, nodes, points, etc., snap to the closest grid point as they are being created or when they are dragged interactively.
If the Display grid lines option is selected, grid lines are displayed according to the Grid line spacing increment. For example, if the Grid spacing is set to 10 and the Grid line spacing increment is set to 5, a grid line will be drawn every 50 units.
If the Display grid points option is selected, grid points are displayed according to the Grid point spacing increment.
