Vertical points of intersection (VPI) entry method

To add an element to the alignment:

  1. Select the Element. If you select Point, enter the Station and Elevation to define the VPI.

    The Slope in field shows the calculated slope value.

    The Slope out field updates when the next element is added.

    For details on other supported elements, refer to the Trimble Access 道路 Help.

  2. Tap Store.

 

  • A vertical alignment defined by VPIs must end with a point.
  • When you edit an element, only the selected element is updated. All adjoining elements remain unchanged.
