Stretch Tool

Use the Stretch tool to lengthen a line.

The Stretch tool is only available if the  Cross section view tool is enabled.

Both straight and arched lines can be stretched by following these steps:

  1. Activate the stretch tool.
  2. Click on a line at a position near the endpoint that you want to modify. The line will be marked and two cross-hair markings will appear. One is fixed at the end of the line, the other one shows the perpendicular point of the mouse position on the extension of the line object.

  3. Move the mouse to shift the perpendicular point on the extension of the line.
    Note: If another line object near the mouse cursor or its extension intersects the marked line, the second cross-hair marking is positioned at the closest intersection point of these two lines not at the perpendicular point.
