528 Permanently out of bounds
Areas which are permanently forbidden to the runner are shown as out of bounds. The screen is superimposed on the normal map detail. A bounding line may be drawn if there is no natural boundary (see symbol 709).
Colour: black or purple.
Line width 0.25mm, line spacing 0.5mm.
This symbol is oriented to north.
As ISOM 2000 but number changed from 529 & 607 to 528.
Defined as area symbol 528.0; this can be drawn with any drawing tool.
Take advantage of editing straight lines into bézier lines where appropriate. Also edge match with care using the control key when drawing to exactly follow boundaries#.
This is a rotatable symbol, the pattern of the fill 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. This is not the same as using the rotation tool which turns the whole object, but not the fill pattern.
The ISOM lays down the permissible combination of screens.
There is no mention of this symbol in the combination section of the specifications. This symbol may be combined with any other suitable screen.
