512 Footbridge
A footbridge with no path leading to it.
Colour: black.
Line width 0.25mm
As ISOM 2000 but ISOM number changed from 511 to 512
Defined as point symbol 512.0, 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.
A crossing point over a watercourse, or other linear feature.
Redefine the symbol so that it can be accurately placed. The default footbridge needs to be dragged at right angles to the stream. By making a new symbol defined horizontally, you can zoom right in (F12-OCAD5 or Shifted OCAD7) and drag along the stream.
Bridges
The "quick and dirty" method is to use the supplied point symbol (512.0 Footbridge) which should be dragged at right angles to the stream. A far neater alternative is to redefine the symbol so that a drag can be made along the stream, which can be performed more accurately. Brian Parker
Bridges, rotation
If the default bridge symbol is used and the map is rotated to fit in a combined print, the bridge symbol should be correctly rotated when the "rotate all symbols" box is checked.
