This subassembly is used to close from the edge of roadway to a daylight point in both cut and fill conditions.
The cut condition includes an optional ditch. The final daylighting link can be omitted for cases where the corridor model needs to be left in an incomplete state. For example, this might be done so that grading surfaces on adjacent properties can tie to the hinge point on the uncompleted roadway. This subassembly is one of a group of Getting Started subassemblies used for simple roadway modeling, and for tutorial and training purposes.
You can also specify optional lined materials for daylight and other links (All Links, Daylight Links, Fill Links Only, and None).
Attachment
The attachment point is at the inside edge of the ditch foreslope for cut, and at the inside edge of the daylight link for fill.
Input Parameters
Note: All dimensions are in meters or feet unless otherwise noted. All slopes are in run-over-rise form (for example, 4 : 1) unless indicated as a percent slope with a “%” sign.

None.
Behavior
The attachment point is tested to determine if it is in cut or fill. If it is in fill, the fill daylight link is extended to the Daylight Surface at the given Fill Slope. If in cut, the foreslope, ditch bottom, and backslope are added, and the cut daylight link is extended from the end of the backslope to the Daylight Surface at the given Cut Slope.
This subassembly optionally lets you add a lined material. You can specify three ranges of slopes. Material type 1 is applied if the slope of the links is up to the specified slope value. From slope 1 to slope 2, the second type of material applied. Similarly, if the slopes of links fall within slope 2 and slope 3 values, then material 3 is applied. If the link slopes are flatter than slope limit 3, then no material is applied.
If a lined material is added to the subassembly, then parallel links are added to the daylight links with specified thickness. Bottom level links are coded with Datum and daylight links are coded with Top. Shapes enclosed by these materials are coded with material name.
Layout Mode Operation
In layout mode, this subassembly draws a generic cut and fill slope with arrows at the ends.
