Chapter 1 Using the Grading Commands

NOTE

If you do not erase the old polyline, then you may have trouble selecting

the new polyline definition because there are now two objects in the same

location.

The following illustration is an example of the Add Vertices command:

Calculating Daylight Points Based on

Multiple Slopes

The Create Multiple command on the Daylighting submenu reads your

footprint polyline and calculates daylight information based on the slopes and

daylight surface you have specified. You can specify the fill slope and cut slope

at each individual vertex of the entity you select, as well as transition from one

slope to another over multiple vertexes on the entity. When the command

calculates the daylight information, it does not add anything to your drawing.

Rather, it stores the calculated daylight data within the entity you selected.

For a more accurate daylight line definition, you can add additional vertices to

the polyline footprint with the Add Vertices command. Daylight points are

calculated from each vertex, so the closer they are together, the better the

definition is.

To calculate the locations of daylight points using multiple slopes

Select the current daylight surface.

For more information, see Selecting the Daylight Surface in this chapter.

Use the Add Vertices command to add vertices to the polyline to provide more

information for the daylight calculation.

From the Grading menu, choose Daylighting ä Create Multiple.

Select the polyline.

Select the side of the polyline to place the daylight points on. A temporary

arrow is displayed indicating the daylight point offset direction for the current

polyline vertex.

The following prompt is displayed:
