Add a key and hub
Create a feather key and groove in one step with Creo Elements/Direct Part Library. You can even create a radial pattern of feather keys around a shaft, as shown below.
By default, feather keys are added as user-defined features and can be easily modified like other features. You can deactivate this function in the Defaults dialog found in the Modify section of the Feather Keys menu.
To add a feather key,
1. The position of the groove and key are defined on a workplane that is tangent to your cylindrical face. See Create a workplane for keys if you do not have a workplane.
2. Click Part Library and then, in the Shaft/Hub group, click the arrow next to Feather Key.
3. Click Create Feather Key. The Feather key dialog box opens.
4. Click Type and select a Key types.
5. Select the Shaft, which is the cylindrical part that will be grooved, or set the ShaftDia (diameter).
6. Click Position and select the position on the workplane.
7. Click Direction and select a point on the workplane in the direction you want the groove.
8. Select the type of groove to cut:

10. You can click Elongate keyway and specify a start point and direction.
11. Keyway in hub: This option also creates a groove in the hub part. Check the option then select the hub part in the viewport. The hub is the part that the key locks onto the shaft.
12. Multiple creation: To create more than one groove and key around the shaft, select Radial in this section then select the axis, enter the angle from one key to another, and enter the number of keys.

Direction (workplane): The direction that the groove should be cut, relative to the workplane.
Dimensions: Click on Width or Length to select from a list of standard parts. The Height is set when you select a width, and should not be changed manually.
