Clearance
| Control | Description |
|---|---|
| From Long Section | Input the long section to compute the height difference from. |
| To Long Section | Input the long section to compute the height difference to. |
| Height Clearance | The smallest height difference between the From Long Section and the To Long Section. |
| From 2D Distance | The reduced distance along the From line or pipe, to the location determined from the horizontal offset to the From coordinate. |
| From Height | The height of the From Long Section, where the clearance is a minimum. |
| To Height | The height on the To Long Section, where the clearance is a minimum. |
| Distance | The horizontal distance from the start of the alignment to where the minimum clearance occurs. |
| Chainage | The chainage where the minimum clearance occurs. |
- A minimum clearance is computed when the From Long Section and To Long Section are picked from the long section view or selected from the list.
- Click OK to refresh the values or compute the clearance when you type the long section names.
- Configure the Distance Type in Units Options.
- Configure the precision in the Precision Options.
