An area presenting danger to a competitor.
ISOM number changed from 608 to 710.

OCAD Methods

Defined as area symbol 710.0; 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 match edges.

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.
