Place a trench by bottom cardinal point and top slope - Intergraph Smart 3D - Help - Hexagon PPM

In the Grids task, create grids as needed for drawing the trench path.

In the Civil task, click Place Trench Command .

Click Path on the Place Trench Ribbon, 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. See Modify a trench feature.

Type a value for Top Slope.

Click Finish to create the trench. An example trench elevation is shown below.

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)
