Single to determine the daylight match line at a specified

slope. This command applies a constant slope to the

entire polyline footprint.

The command checks for both cut and fill automatically.

It also draws temporary objects that represent the

location where the projected slope matches into existing

ground.

From the Grading menu, choose Daylighting

➤ Create

Multiple when you need to daylight using different slopes.

For example, when one area of the proposed plan falls

outside of the construction limits (such as the property

line or building), you can change an individual slope or

group of projected slopes. The command draws

temporary objects that show the new daylight match line

location, as shown in the following illustration.
