Ejector pin clearance holes are used to show where the ejector pins that will eject the molding or casting are placed. They have no effect on the geometry of a molding or cast result.

You can include ejector pin clearance holes in a UDF. When you place a group with such a feature, the system prompts you to select the radial value for each feature individually. After each radius is selected for the ejector pin hole, its axis is highlighted.
