### Updating Nominals from CAD

You can update the nominals of features based on an imported CAD file. This makes it possible to easily update features' nominals to match the nominals of the CAD model. This is useful in these situations:

- You have already started measuring features without any CAD, but you now have CAD and want to update the nominals.

- The CAD model you've been using has been updated.

To update features' nominals from CAD:

1. Import a CAD model by using the File | Import menu item. For more information on this topic, see "Importing a CAD file" in the "Using Advanced File Options" chapter.

2. Click Operation | Features | Update Nominals from CAD.

3. You can update all nominals by clicking the All menu item. To update just the currently selected nominal feature, click the Current menu item.
