Creating User-Defined Stamping Features

Two user-defined stamping features are available:

Create a punch and a die:  define the punch and die features, select a wall, choose the punch and die as stamping elements, select an edge on the wall and give an angle for orientation purposes.
Open and cut faces: define the punch, select a wall, define the cutting faces and opening faces of the punch, select an edge on the wall and give an angle for orientation purposes.
Edit a user-defined stamp: double-click the existing stamp and change its type, or select, or remove cutting and opening faces

What You Should Know 

In both tasks illustrating either a stamp based on a punch and a die, or a punch with cutting and opening faces, the punch positioning is defined as below:

Defining the Punch in Relation to the Wall to be Stamped

The punch is defined within the absolute (default) axis-system of the .CATPart document. (o, x, y, z) is the axis associated with the punch. The punching direction on the punch (Dp) must be equal to z.

The punching direction on the wall (Dw) is normal to the selected wall face, and is oriented from the selected wall face towards the opposite face.
The punch is applied matching Dp on Dw and matching the punch's (x, y) plane onto the selected wall face:

Defining the Die in Relation to the Wall to be Stamped

This is useful only when defining a punch a die, and does not apply to punches with cutting and opening faces.
The die is also defined within the absolute (default) axis-system of the .CATPart document. (o, x, y, z) is the axis associated with the punch. The punching direction on the die (Dd) must be equal to z.

The illustration is a section view of the die.

The die is applied matching Dd on Dw and matching the die's (x, y) plane onto the selected wall face:
