Rotation Range - Minimum to Maximum Angle
Rotation Considerations
l By default, the range is selected, with a full search range from 180 to -180. This
means that the Locator will search for objects in all orientations.
l The rotation range spans counterclockwise from the specified minimum angle to the
specified maximum angle. The preceding graphic illustrates the impact of selecting a
minimum and maximum angle.
l
Check Use Nominal to search for objects at a specific angle of rotation. When a Nom-
inal value is applied, the Locator does not compute the actual rotation of instances;
instead, the instances are positioned using the Nominal rotation value.
l If you want to search for an instance at a Nominal rotation but need to compute its
actual rotation, disable the Use Nominal checkbox and enter a small range, such as 89
to 91.
l If a nominal value is used with objects that present a slight variation in rotation, the
objects may be recognized and positioned with reduced quality because their true rota-
tion will not be measured. In such a case, it is preferable to configure a narrow rotation
range, such as ± 1 degree, instead of a nominal value.
Nominal Scale Factor
Nominal Scale Factor sets the required scale factor for an object to be recognized.
This constrains the range of scale factors the Locator will search for.
