Property Value

Type: Double
The angle overlap threshold (in radians).

Events

Event Type	Reason
ICogChangedEvent Changed	Fires when this property changes. The following state flag may be affected: SfOverlap

Exceptions

Exception	Condition
ArgumentOutOfRangeException	The supplied value is less than zero, or exceeds the maximum.

Remarks

Two result candidates are said to overlap in this angle zone if the absolute difference between their angles is less than or equal to the given Overlap threshold.

When two pattern instances overlap in volume, and also overlap in all three angle zones, 3DAlign discards the pattern instance with the lower score. See the XYZOverlap property of the Cog3DAlignRunParams class for more information.

The default values for an angle zone depend upon which zone it is:
