The Area Snap button, located in the Work Area toolbar (at the bottom right of your screen), is useful when working in the Floor Plan area. Whether you work with a grid or not, the Floor Plan area is a rectangular pattern of dots that extends over the area that you specify as the drawing limits. Using the Floor Plan area is similar to placing a sheet of graph paper under a drawing. The grid helps you align objects and visualize the distances between them. The grid (Floor Plan area) is not plotted. If you zoom in or out of your drawing, you may need to adjust grid spacing for the new magnification.
Area Snap restricts the movement of the crosshairs to intervals that you define. When The Area Snap mode is on, the cursor seems to adhere or "snap" to an invisible rectangular grid. Snap is useful for specifying precise points with the arrow keys or the pointing device.
As you work, you can turn Area (Grid) and Area Snap mode on and off, and you can change the grid and snap spacing.
Area Snap spacing does not have to match grid spacing. For example, you might set a wide grid spacing to be used as a reference, but maintain a closer snap spacing for accuracy in specifying points. For instructions on changing the snap spacing, click here.
Click the Area Snap button in the Work Area toolbar to activate it. When Area Snap is deactivated, items move freely.
