If features are selected for containment, the containment "Type" on this form and on the associated Operation Definition Form will be set to "User_Defined."  The "Type" on this form can be set to "None" or "Auto" and that will take precedence.  The list of features specified for containment will still exist, but the "Type" you select will then take precedence.

How to avoid clamps and tables automatically

If you want to make sure clamps and tables are avoided automatically, set the Containment field to "Auto." Then there is  no need to add clamps or tables to the Features list of an operation.

How to define clamp avoidance manually

During intelligent hole making and 2-1/2 axis milling operations, clamp avoidance is performed automatically.  During 3 axis, QuickMilling and 5 axis milling operations, if containment Type is set to "None", no clamp avoidance will be performed.  If set to "Auto", clamp avoidance will be performed automatically.

If set to "User-Defined" you need to define those clamps to be avoided.  Here is the basic procedure:

1. Your clamps should be components in your CAM assembly and their CAM class attributes should be set to "clamp."  This should be the case for all tool path operations.

2. Add a surface or solid CAM feature of type "containment"  to each clamp component that you wish to avoid.

3. Select the Feature Mgr button on this form to display the Features in Containment Form.

4. From the "In Plan" list, select the CAM features you created in Step 2 and add them to the "In Opdef" list.

5. Because of your selection in Step 4, the "Type" field the Containment Definition Form is automatically set to "User Defined."

The clamps associated with the features will then be avoided by the active tool path.
