Create DIN 509 type E and F undercuts on shafts or holes in one operation with Creo Elements/Direct Part Library. You can create the undercut with or without a bolt, and you can create a chamfer on the counterpart.
By default, undercuts are added as user-defined features. You can change this in the Defaults dialog box. Click (dialog box launcher) in the Feature group to open the Defaults dialog box.
To create an undercut,
1. Click Part Library and then, in the Feature group, click the arrow next to Undercut.
2. Click on the undercut type you want. Select a command in the Bolt and Undercut section if you also want to add a shaft onto a face. The shaft is not threaded.
3. Set the undercut dimensions and options. Please note the following:
◦ If you create a bolt and choose to add a chamfer to the end of the bolt, input the distance shown here:
◦ Stress changes the geometry for different load demands placed on the shaft. These options are defined by the DIN 509 standard.
