The Floor/Grid Settings dialog box contains two groups of settings. The Floor Settings control the size and appearance of the floor. The Grid Settings control the spacing and appearance of the grid. The floor size settings control the overall grid size, even if the floor display is turned off.
By default, the floor is specified as visible in a new factory layout. It is set to resize automatically once components are moved outside the default boundary. You can control the floor color and whether a border displays.
The Minor Grid Spacing controls the distance between grid lines. By default, every other grid line is displayed as a major grid line. You can enter an integer from 1 through 512 to change the frequency of the Major grid lines.
After making changes to the floor settings, floor style, grid settings, or grid style, click the Make Default button to store your changes for all subsequent factory layout sessions.
You can still make changes to the floor and grid settings after clicking the Make Default button. If you want to return to the settings stored under Make Default, click the Restore Defaults button.
