OCAD Methods

As this is a line object it can be drawn with any tool. If the bézier tool is used, care must be taken as dot spacing is dependent on location of nodes and handles. See bézier topic for more information.

Drawing Considerations

See minimum dimensions but specifically - shortest dotted line: at least two dots.

Do not use within areas of marsh.
