Measuring the Distance Between Two Points
RockPlot2D | Measure | Distance

Use the Distance menu item or toolbar button to measure the distance between two points drawn on the RockPlot2D screen display. The computed distance is displayed in the window's data pane.


  1. If necessary, open the diagram for which you wish to compute line lengths (see Opening Plot Files) or click in the current RockPlot2D window containing the diagram.
    ! It’s important that this image be created at equal units horizontally and vertically for the distance computations to be accurate. The image does not, however, need to be displayed in RockPlot2D at equal scales (vertical exaggeration can be < or > 1).
  2. Select the Measure | Distance menu item, or click on the Measure | Distance button at the top of the screen .
    The Distance button is available in the Measure drop-down menu.

    The program will be in "Measure Distance" mode, as noted at the bottom of the screen.

  3. Click on the starting point of the line.
  4. Click on the ending point of the line. (Endpoint order is not important in determining distance.)
  5. The program will connect the points with a line on the screen display. The distance between the points, in your map or diagram coordinates, will be displayed in the data window to the right.
  6. Repeat this process if you wish to digitize another line for distance computation.
  7. To terminate the Measure Distance mode, click the Measure Distance X button at the bottom of the window, or click the arrow button at the top of the window, or press the Shift+Escape keys.

! If you recreate or close the RockPlot2D window before copying the data to the clipboard, it will be lost. The data is not stored in the Rw2D file.
