They also have an inner protected volume, which means that no other volumes in the same body can penetrate this area. If you add a pocket to a shelled body, it creates supporting walls, if necessary.
The direction of a pocket always goes from the inside to the outside of the body.
This task shows you how to create a pocket.
|Open the Pocket.CATPart document.|
Checking the Clearance volume option in the Distance tab creates an infinite protected volume outside of the pocket and in the opposite direction in which the pocket depth is applied, which prevents any material from the same body from penetrating the area above the pocket. Here is a preview of the feature. As a protected area, the clearance volume is displayed in red:
Checking the Protected volume option reserves space inside of the pocket. A protected volume is a space that nothing from the same body can penetrate inside of. As a protected area, the protected volume is displayed in red:
Checking the Only outside option creates the pocket only outside of the shelled body. Thus, the profile of the pocket must extend outside of the walls in order for the pocket to be visible. This option is not available when Protected Volume is selected.
The default neutral element (defines a neutral curve on which the drafted face will lie) is the Profile plane. The other possible neutral elements can be:
Click Draft tab. Select Intrinsic to feature in Draft behavior field. Enter 2deg for Angle and 7deg for Clearance volume angle.
The Lateral radius option enables you to fillet lateral edges.
The Floor radius option enables you to fillet bottom edges.
Click Fillet tab. Check the Lateral radius and Floor radius option to fillet lateral edges and the floor edge with 5mm radius value.
To define the wall, you can set one of the two options available from the Type drop down list:
You can control whether the wall is constructed inside or outside
of the selected profile for Direction. The default is an outside wall thickness.
For the purposes of our scenario, set the Enter thickness option and enter 7mm in the Thickness value field.
