Rerecognition

You can use Rerecognition when you have a new revision of a part you have already used feature recognition on. Use rerecognition to recognize features in a new model and compare the features to an existing model.

Select Features & Manufacturing tab > Features panel > AFR > Rerecognize to display the Rerecognition wizard.

Note: When rerecognizing features in a new model, ensure you use the same alignment as the original.

The new features are classified into these categories:

• unchanged features — These features are identical to existing features. They are ignored in the rerecognition process.
• new features — These features are not part of the existing features and therefore are assumed to be new. You can create these features in the Rerecognition wizard.
• modified features — These features have the same shape or size as existing features, but parameters like depth, bottom radius or chamfer distance have been modified. The Rerecognition wizard asks you if want to replace the existing features with their modified versions.
• deleted features — These features exist in the current set of part features, but were not found in the new model. You are offered by the Rerecognition wizard the option of deleting these features. There are many possible reasons that this feature is in your existing set of features but was not automatically recognized, so you should be careful about deleting these features. If the feature has clearly been deleted, you can comfortably remove it. If the feature was created through interactive methods, you probably want to keep this feature. If you are uncertain, you should preview each feature and decide on an individual basis.
