Adjust Level by Attribute

The Adjust Level by Attribute command (in GIS > Attributes) allows you to use the attribute values of points and linestrings to adjust their levels. It can be applied to points either before or after feature code processing, and includes an option to retain a copy of the original point at its existing level.

  1. Click in the Entities selection field and then in a graphic view select the lines/points. Click Options button for additional selection options.
  2. Select the type of attribute to be used on the line or point.
    • FXL – for feature attributes
    • 12D – for 12d attributes
  3. In the Attribute unit dropdown, select the unit type used for the attribute value.
  4. Check Create copies of adjusted points at the original level to retain a point at its original level after moving the original point, and assign the retained point a new feature code if required.
  5. Enter the target Attribute name into the appropriate Elevation Type. If more then one field is filled out, then they will be applied in order from top to bottom.
    • Absolute – Sets the elevation of the line or point to the attribute value.
    • Offset – Adjusts the elevation of the line or point by the attribute value with a positive number going in an upward direction.
    • Depth offset – This will adjust the elevation of the line or point by the attribute value with a positive number going in a downward direction.
  6. Click Apply to adjust the levels on the target objects.
  7. Click Close to end and close the command.

    Note: Any Linestrings with elevation edits and that contain vertical tab data will have their levels converted to the horizontal tab. If controlled by point ID, they will be converted to be controlled by coordinates.

    This feature only works on points and linestrings.
