Digitizing Polygons in RockPlot2D
RockPlot2D | Digitize | Polygon

Use the Polygon menu item or toolbar button to draw polygons on the RockPlot2D screen display and record the X,Y coordinates of their vertices in the data pane.


  1. If necessary, open the diagram for which you wish to draw polygons (see Opening Plot Files) or click in the current RockPlot2D window containing the diagram.
  2. Choose the Digitize | Options command if you wish to view/change the color and style of the polygons to be drawn on the screen. You should also check the number of decimal places specified for the coordinates so that you will get the accuracy you need. See Measurement and Digitizing Options.
  3. Select the Digitize | Polygon menu item, or click on the Digitize | Polygon button at the top of the screen .
    The Polygon button is available in the Digitize drop-down menu.

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

  4. Click on the starting point of the polygon. The program will display a symbol on the image to mark the point. The program will record the first point's coordinates in the data window. (Don't see the data window? Click here.)
  5. Continue digitizing points on the screen display along the perimeter of the polygon. These coordinates will be recorded in the data window.
  6. To close the polygon, double-click on the next-to-last endpoint. The program will connect the last point digitized with the original point on the screen display. The data block will be flagged with an "End-Polygon:" notation.
  7. Continue digitizing polygons on the screen display as you wish.
  8. To terminate the Digitize Polygon mode, click the Digitize Polygon x button at the bottom of the window, or click the Edit button at the top of the window, or press the Shift+Escape keys.

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