Pick and Place Function
5–9
As Figure 5.8 shows, pick and place points are located at the window center
(A) and at the four corners (B, C, D, and E).

These pick and place points have the following functions:
•
Center of window –– The center pick and place point enables you to
move the entire window anywhere within the image field without
changing the window’s shape or size.
•
Corners –– The corner pick and place points enable you to drag each
window corner in any direction. The corner opposite the picked corner
always remains anchored. Thus, you can change the window size
anywhere between its smallest size and the limits of the image field.
Figure 5.9 (page 5–10) provides two examples that demonstrate the operation
of all pick and place operations for a rectangular gage:
•
Example 1: The lower–right corner of the window is picked at point D,
dragged to point D
′, and then placed at point D′, thereby decreasing the
size and changing the shape of the window.
•
Example 2: The center of the window is picked at point A, and the entire
window is dragged to point A
′, and then placed at point A′.
