• You can use Trim to quilt/refmodel on all ejector pin types. To define the quilts, click EMX Part Mode > Preparation > Identify trim faces or EMX Assembly > Preparation > Identify trim faces.
◦ If a trim surface is defined then Creo Expert Moldbase Extension uses the Solidify feature to create the trimmed surface.
◦ If no trim surface is defined then Creo Expert Moldbase Extension trims the ejector pin against the solid using the Mold Design Trim to Geometry.
• When you use an ejector pin as a core pin, you must assemble a different hole type to the extracts. Select these hole types from a list of fixed rotation hole types.
