To demonstrate the manual way, you can start again from the initial model, using the Undo command. Click the Manual thumbnail. Select the Fillet type in the dialog box. Check the Chain Faces option in the dialog box. Select one fillet face belonging to the part.
The order in which you recognize features must be the opposite of features creation possible order. That’s why we usually start the recognition process with “Fillets” recognition.

Click Apply in the dialog box. We can repeat the same operation with the symmetrical fillet. We end up with new V5 features in the tree: “EdgeFillet.1” and “EdgeFillet.2”
As the Chain Faces option is on by default, the application includes propagated faces in the selection. This is why the “Selected Objects” field shows three faces, while we selected only one geometrical face. All selected faces are highlighted and numbered in the geometry area too.

Select the Boolean type in the dialog box. Select the five inner faces of the slot as shown.
Boolean Feature recognition is used when the initial geometry is made of complex shapes also when the recognition of standard features fails. Because the cavity of this part is not easily identifiable, we need to use the Boolean option.
