### Aligning Measured Auto Features to CAD

The process described here is only available when measuring Auto Features, with a manual laser probe (on a portable arm), with imported CAD data. This allows you to select the actual measured features from the pointcloud that correspond to selected nominal features from the CAD.

To align measured auto features to CAD nominals:

1. Import CAD data.

2. Open the Auto Feature dialog box for a feature that will be included in the manual alignment.

3. Select the nominal location for the feature by clicking on the CAD surface next to the needed feature.

4. Change any auto feature parameters as needed and click Create. The Auto feature is added to the part program.

5. Repeat steps 2 through 4 for each auto feature that will be included in the alignment.

Note: PC-DMIS automatically adds a new extraction COP when you begin creation of a new laser auto feature. The features of the manual alignment may be included in the same pointcloud. The COP from which the laser auto features is extracted is specified from the "Laser Probe Toolbox: Laser Scan Properties tab".

6. Execute you part program. PC-DMIS prompts you to scan the laser auto features as part of a Portable Laser Alignment.

7. Scan the part to include the auto features for the manual alignment.

8. Press the Done button on your arm when you have completed feature measurement. More than one scan may be needed to adequately define each feature.

9. PC-DMIS now prompts you to define the first manual alignment feature. Follow the instructions provided in the dialog box and status bar and then press OK. At the end of selection the preliminary form of the auto feature is displayed.

10. Repeat Step 9 for each of the manual alignment features.

Note: PC-DMIS solves the laser auto feature with the theoretical values from the CAD and actual values from the measured pointcloud.

11. Select the Insert | Alignment | New menu item (Ctrl+Alt+A) to open the Alignment Utilities dialog box.

12. Select the alignment features from the list box and click Auto Align. PC-DMIS aligns the defined features from pointcloud with the corresponding CAD nominals. The manual laser alignment has been established.
