540 Special man-made feature
Special man-made features are shown with this symbol. The definition of the symbol must be given in the map legend.
Colour: black.
Line width 0.16mm
This symbol is oriented to north.
As ISOM 2000 but line width was 0.175mm
ISOM number changed from 542 to 540.
Defined as point symbol 540.0, 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.
