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

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

2. In the Civil task, click Place Trench .

3. Click Path , and define the path of the bottom of the trench.

4. Select a cardinal point at the bottom of the trench: Bottom Left , Bottom Center , or Bottom Right .

5. Select Define start depth and top slope as the placement method.

6. Select the parent system of the trench run.

7. 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.

8. Type a value for Top Slope.

9. 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)
