Starting
Open the “FR1_Exercise_start.CATPart” file
Check that “Solid.2” is active
If not, choose “Define in Work Object” in itscontextual menu to activate it.
In the “Part Design” workbench, click the“Automatic Feature Recognition” icon
A “Feature Recognition” panel will bedisplayed
Check you are in the “Automatic” thumbnail We will see the 2 different ways to recognize
“dress-up features”, automatic or manual; youcan practice both of them.

Feature Recognition: Dress-up Features (Fillets) 2/2
As the Chain Faces option is on by default,the application includes propagated facesin the selection.
This is why the “Selected Objects” fieldshows three faces, while we selected only
one geometrical face.
All selected faces are highlighted and
numbered in the geometry area too.
Click “Apply” in the panel
We can repeat the same operation with thesymmetrical fillet
We end up with new V5 features in thetree: “EdgeFillet.1” and “EdgeFillet.2”

Feature Recognition: Boolean feature 1/2
Select the “Boolean” type in the panel
Select the slot 5 inner faces as shown
This step illustrates a Boolean Feature recognition 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.

Feature Recognition: Features Rework
In “PartBody” contextual menu, select “Define In WorkObject”
This action will activate the PartBody. We will then be ableto visualize the newly created V5 features.
We are now provided with a V5 structure that can be
modified the usual way; for instance:Add a “Smooth Propagation” option to the “Draft”
Change the “Groove” profile by editing the support sketch
Change the “Edge Fillet” value
