Example: Punching several parts
In this example you will punch profiles in workplane w1 (the active workplane) into the two parts 1 and 2. Shown below are the workplane and profile and the resulting parts.
After creating the workplane and profile:
1. Click Modeling and then, in the Model group, click the arrow next to Remove.
2. Click Punch. The Punch Stamp dialog box opens. The part is set to p1 (the active part) and the workplane is set to w1 (the active workplane). You do not need to change the workplane, but you do need to create a list of parts to punch.
3. Specify the parts to machine:
a. Click Parts.
b. Click Select.
c. Click Start (in List).
d. Click parts 1 and 2.
e. To complete the list of parts, click End (in List). Creo Elements/Direct Modeling highlights the parts in the graphics area.
4. Click to complete the operation. Creo Elements/Direct Modeling punches the parts.
