GROUP_DIFF

GROUP_DIFF is a group operation and subtracts one group from another; the result is a new group. The new group can be used with GROUP_PLACE, as variable or in another group definition.

Syntax

GROUP_DIFF (g_expr1, g_expr2)

Parameters

g_expr1, g_expr2 (string): group name or variable or result of group operation

g_expr1 is the minuend, g_expr2 the subtrahend.

Remarks

For group operations, the groups must have been defined already. They also can be results of other group operations.

The minuend's surface attributes are used for the new group.

Usable since script version 1.1 (Allplan 2012-1).
