#### Step 4: Create a DCC Alignment

DCC alignment is inherently more accurate due to the fact that features (measured in step 3) used were measured under computer control at higher magnification, with higher density of points and refocusing. The front edge (Datum C) and the center point of the arc (Datum B) are used in this example.

To create a DCC alignment:

1. Select the 3 2 1 Alignment button from the Vision toolbar. The Alignment Type dialog box appears.

2. Select the Line-Point 2D alignment and click Next >>. The 2D-LinePoint dialog box appears.

3. Select DATUM C from the List of Available Lines and associate it with XPLUS axis from the Associate with axis drop-down list.

4. Click Next >>. The 2D-LinePoint Alignment - Origin dialog box appears.

5. Select DATUM B from the list of Available Points and click Next >>. The Line-Point dialog box appears.

6. Click Finish to insert the alignment command into the part program. The DCC (or refined manual) alignment is complete.

Click the +/- (expand/collapse) next to the new alignment in the Edit Window. Notice the alignment steps that were created under the alignment command by the 3 2 1 Alignment Wizard.
