To create or edit strings derived from other strings
If required, you can define a new string derived from an existing string in the GENIO file. You can then edit or delete strings derived from existing strings, as required, from the tap and hold menu.
To define a new string, you must have selected an alignment in the new GENIO road. New strings are created as 3D strings.
- Select a GENIO file and define a new road or select an existing road and tap Edit.
- From the tap and hold menu, select New string.
- Enter the string name.
- Select the string that the new string will be derived from. You cannot define a new string relative to a 5D string.
-
Select a string derivation method and then enter values that define the new string.
The following figure illustrates the Offset and calculated slope method where the Derived from string (1), the Offset value (2) and the Calculated from string (3) define a new string (4) on the slope between the Derived from and Calculated from strings.
-
Tap Accept.
The new string appears, colored teal.
When you define a new string by the Offset and calculated slope method, the new string is defined only where the station values for the Derived from and Calculated from strings match.
