About Feature Recognition
Feature Recognition is a process that semiautomatically identifies features imported from any Boundary Representation model (IGES, STEP, etc). You can select multiple geometry entities to replace simultaneously. The following feature types are supported:
Hole
Extrusion
Chamfer
Fillet
Round
Slot—A cut on the external contour of a surface.
Pattern
Working with the Feature Recognition Tool
Select a desired class of feature to search for, then select either a seed surface (to detect multiple features of the type) or a seed edge (to detect a single feature of that type). When the imported geometries are recognized as features, they are analyzed and removed from the model. Remove features are added in the Model Tree and the imported geometric features are replaced by equivalent Creo Parametric features.

The Feature Recognition user interface is only available when an open and active part contains import features.
Feature recognition identifies only candidate geometries that are created on solid parts.
When the Remove Surface function fails, chamfer and fillet features cannot be created. Hole and extrusion features are created on the existing surface without removing the original geometry.
You can manually remove a surface and recreate it as a new feature without using the Feature Recognition tool. Refer to the Creo Parametric Online Help for details on the Remove tool.
Feature Recognition validates the model to ensure that the new features do not modify its geometry. If the geometry changes, a warning message appears in the message area.
