OCAD Methods

Defined as point symbol 535.0, can be drawn with any drawing tool.

This is a rotatable symbol, it can be rotated with the direction tool and will rotate with the map if the “include symbols” box is checked when the map is turned.

Care when drawing is needed, a click will place the symbol; a click with drag will rotate the symbol in the direction of the drag. To correct this, redraw carefully. Don Scarrott has written a utility that straightens all rotated symbols.

Pictorial Descriptions
