Extend By

The Extend By functionality allows you to lengthen or shorten the section by moving its Start or End position through a specified amount.

1. From the main menu toolbar select Position > Extend > By.

   The Extend Section - Explicit window is displayed.

   

   A label is placed at either end of the section to identify the Start and End locations.

2. Use the Extend drop-down menu to select which end of the section is extended.

   The choices are Start, End or Pick.

   If the Pick option is selected you are prompted to select the end of the section that is re‑positioned when the Apply is selected.

3. Select the appropriate Extension by option to move the end of a section by Distance or by a Proportion of the section's current length.

4. Enter the required value.

   Entering a positive value lengthens the section and entering a negative value shortens it.

5. To maintain the position of any Secondary Node owned by the section, select the Maintain Sections’ Node Positions checkbox.
