For this alignment, only one point was taken (previous step) so no rotational datum was measured. In this example, it is assumed that the part is reasonably square to the machine axis. The single point will be used to establish the XYZ origin.
To create a manual alignment:
Select the Insert | Alignment | New menu option. The Alignment Utilities dialog box appears.
From the feature list, select PNT1.
Next to 
X, Y,
and Z,
select the check boxes.
Click the Origin button.
Click OK to save and exit. The X, Y, and Z zero points all move to the edge point.
Executing the measurement routine that you just created moves the origin to this point on the actual part. To do this:
Select the Vision tab.
From the Edit
Window toolbar (View | Toolbars | Edit Window),
select Mark All (
).
When asked if it's okay to mark manual alignment features, click Yes.
From the QuickMeasure
toolbar, select Execute (
).
When prompted, measure point PNT1 by aligning the target (cross hair) to the corner and clicking Continue. Alternatively, you can drag and drop the cross hair. It snaps to the edge.
When the measurement routine execution finishes, select the CAD tab.
From the Graphic
Modes toolbar (View | Toolbars | Graphic
Modes), select Scale-To-Fit (
).
