Specifies the method used to calculate the slope and depth of the trench.
The following methods are used with top cardinal points when the path is drawn at the top of the trench. These methods calculate the slope of the bottom surface of the trench. Select one of the following:
|
|
Define start and end invert elevation - The bottom slope and the depth are calculated by the software. See Place a trench by top cardinal point and invert elevations. |
|
|
Define start depth and end invert elevation - The bottom slope and all other depths are calculated by the software. See Place a trench by top cardinal point, start depth, and end invert elevation. |
|
|
Define start invert elevation and bottom slope - The depth is calculated by the software. See Place a trench by top cardinal point, start invert elevation, and bottom slope. |
|
|
Define start depth and bottom slope - All other depths are calculated by the software. See Place trench by top cardinal point, start depth, and bottom slope. |
|
|
Define start depth (Bottom slope is parallel to top slope) - SSee Place a trench by top cardinal point and start depth with bottom slope parallel to top slope. |
The following methods are used with bottom cardinal points. These methods calculate the slope of the top of the trench. Select one of the following:
|
|
Define start depth and top slope - All other depths are calculated by the software. See Place a trench by bottom cardinal point and top slope. |
|
|
Define start depth (Top slope is parallel to bottom slope) - See Place a trench by bottom cardinal point with top slope parallel to bottom slope. |
