-
In the Grids task, create grids as needed for drawing the trench path.
-
In the Civil task, click Place Trench
.
-
Click Path
, and define the path of the bottom of the trench.
-
Select a cardinal point at the bottom of the trench: Bottom Left
, Bottom Center
, or Bottom Right
.
-
Select Define start depth and top slope
as the placement method.
-
Select the parent system of the trench run.
-
Select a trench Type and its respective cross-section.
The start depth is defined by the Catalog during placement. You can modify this after placement.
-
Type a value for Top Slope.
-
Click Finish.
The trench is created, as shown in the following example trench elevation:
1 - Drawn trench path with varying global Z-coordinates along the path
2 - Defined bottom cardinal point for cross-section
3 - Defined start depth from trench cross-section
4 - Defined top slope
5 - Defined footing thickness from trench cross-section
6, 7, 8 - Trench depths computed by (rim elevation from top slope) - (invert elevation from global Z-coordinate of drawn path)
