You can update the nominals of features in the Edit window based on an imported CAD file. This makes it possible to easily update your features' nominal (or theoretical) values to match the nominals of the CAD model. This is useful in these situations:
You have already measured features without any CAD, but you now have CAD, and want to update your features' nominals.
You want to update your features' nominals to match an updated CAD model.
To update your features' nominals from the CAD:
Select File | Import to import the CAD model you want to use. For more information on how to import a model, see "Importing a CAD file" in the "Using Advanced File Options" chapter.
Select Operation | Features | Update Nominals from CAD and choose one of these submenu items:
All - Updates all the features' nominals in the measurement routine.
Current - Updates only the selected feature's nominals.
The status bar shows the operation results as it runs.
