Create a pocket for the ejectors in the relevant parts.
Note: It is recommended to trim the ejectors and then create a pocket for them.
Required Step 1 
Pick ejectors for which pockets are to be created.
Notes:
Only ejectors can be picked.
An ejector can only be picked once for an ejector pocket operation.
Required Step 2 
Define the required pocketing parameters. See Ejector Pocket Automatic Cutting Analysis.
Press the Set the Constant Fit Length parameter to display the types of pocketing parameters.

As Catalog
Set the Constant Clearance length
Notes: For all the parameter types, other than As Catalog:
Use the Expand
/ Collapse 
toggle to hide/show other information lines and the Picture button.
Example:
Press the Picture button to display a picture of the parameters currently being set.
If you choose As Catalog, none of the other parameters are displayed and the cut will done with the defined catalog cutting object.
Set the Constant Clearance length
|
|
L Clearance: Define the ejector clearance length. D Clearance: Define the ejector clearance diameter. Except along L Fit, the pocket diameter will be the ejector diameter + the clearance value. Note: L Clearance is constant, i.e. in all the selected ejectors, the length of the clear diameter will be the same.
|
|
|
L Fit: Define the ejector accurate guiding length. Along L Fit, the pocket diameter will be the same as the ejector diameter. D Clearance: Define the ejector clearance diameter. Except along L Fit, the pocket diameter will be the ejector diameter + the clearance value. Note: L Fit is constant, i.e. in all the selected ejectors, the length of the accurate pocket will be the same.
|
|
|
L Fit: Define the minimum ejector accurate guiding length. Along L Fit, the pocket diameter will be the same as the ejector diameter. D Clearance: Define the ejector clearance diameter. Except along L Fit, the pocket diameter will be the ejector diameter + the clearance value. L Clearance round off: Round off the values of Min. L Clearance and Max. L Clearance. Whatever these values may be, the L Fit length must be at least the value set above. Note: L Fit will change to suit the round off value, but can never be less than the defined minimum.
|
|
|
L Fit Through Last: The ejector accurate guiding length will equivalent to the thickness of the last part that the ejector passes through.

Optional Step 1
Pick or unpick components to be cut by the Ejector Pocket. This option is only available when creating an Ejector Pocket. When editing an Ejector Pocket, this option is disabled.
Press OK 
or Apply 
in the Feature
Guide to complete the function.
The Assembly Feature Tree now contains a feature called Ejector Pocket in the MoldDesign Operations branch.
The Part Feature Tree now contains a feature called Ejector Pocket.
Note: The Ejector Pocket feature can be edited or deleted from either of these locations. The Edit returns you to the full functionality of the Ejector Pocket function (except the optional step 1 - Pick or unpick components to be cut by the Ejector Pocket).
In each part that is cut by the ejector pocket operation, an ejector pocket feature will appear. You can invert the cutting direction by editing this feature.
Automatic Cutting Analysis and Location of the Pocket Feature
MoldDesign uses two different analyses to recognize which objects to cut by the ejector.
If the ejectors are assigned to the Ejection System sub-assembly or to the Moveable Side, all objects except the Fixed Side will be cut. In this case, the pocket feature will be created in the Ejection System sub-assembly.
If the ejectors are not assigned to the Ejection System sub-assembly or to the Moveable Side, only objects assigned to the specific assembly will be cut. In this case, the pocket feature will be created in the specific assembly.
Note: In any situation, you can add or remove objects to/from the cutting list.
Working with Ejector Instances
If the picked ejectors are instances (the same component), the pocket that will be created, will be in the same shape but may cut different objects.
If a few ejector instances are picked for different pocket operations, only the first one will be editable. If this first one is changed, all the other instances will also change.
Only if you delete all the pocket operations that were done by the same instance, will the ejector be returned to its original shape.
Ejector instances, other instances which already contain pocket operations, can only be picked separately.
