The manual alignment in this example will consist of a single Edge Point to approximately locate the part. In later steps, additional datums will be measured (under DCC if applicable) to create a final alignment. Before you begin, mount the part so it is reasonably square to the axes of the measuring machine.
To measure the datum feature:
Select the Magnification
tab 
and adjust
the magnification so it is decreased to the minimum setting (zoomed
out).
Select the Illumination
tab 
and set
the Top Light to 0% (Off) and the Bottom Light to 35%.
Select the CAD tab.
From the Graphic Modes
toolbar (View | Toolbars | Graphic Modes),
select the Curve Mode button 
.
Move the machine so the front-left corner is within the FOV as shown below:
From the Auto Feature toolbar, click Edge Point to open the Auto Feature (edge point) dialog box.
Click a point on the front edge, VERY CLOSE to the left corner.
Select the Hit Targets
tab 
.
Change Automatic Target to Manual Hit Target.
Since this is actually a "Manual Target" edge point, the actual point used is where you have physically placed the crosshair.
Click Create to add this edge point to the measurement routine.
Click Close to exit the Auto Feature dialog box.
