Resolution for the angle calculation 6
In this measuring mode, if the component rotation has been calculated incorrectly on account of
ambiguity, you can increase the angular resolution in order to determine the angle of rotation. The
following increments may be used in relation to the resolution in order to determine the angle of
the components: 6
– Simple components:Low resolution:
– Complex components:High resolution

Method for calculating the rotation 6
Here you must specify the number of rotation windows in order to determine the angle: 6
– Automatic selection
The system selects the number of windows.
– SWIN method (Single Window)
Selects a single window. This method is suitable for small and complex components or com-
ponents with fluctuating dimensions.
– TWIN method (Two Windows)
Two windows are selected. This method is particularly suitable for rapid analysis, for PLCCs,
for example. However, this requires the structures to be investigated to lie in the center of the
window. If this is not the case, select just one window (SWIN method).
Integration settings 6
If you click on the 'Integration settings' field, the Integration settings of Size measuring mode
menu will appear on screen. 6

Integration direction 6
In order to determine the angle, select the integration direction towards either the X or Y axis of
the component. We recommend that you select the longer edge. 6
