Are you designing a mold? Once your model design is established, why reinvent the wheel? With Creo Parametric you can quickly duplicate your model’s surfaces and combine the reverse surface with parting surfaces to form a mold component.

First, create a quilt surface on the reference part. Then, that surface can be used in your mold assembly. Here’s how:

  1. Select a surface on your model.
  2. Right-click and select the Tangent Surfaces option. This selects the outer surfaces of the model, as shown below.

  1. Duplicate the selected surface by clicking Flexible Modeling > Move.
  2. On the Attachment tab, clear the Attach moved geometry checkbox.
  3. On the Move tab, click Origin Free (Default), and then select a reference coordinate system from the Model Tree.
  4. On the Move tab, change the Tz (distance) value to zero (0.00). This ensures that the duplicate surface lies exactly on the model.
  5. Click the green check mark to apply and save the changes.

Now, the new surface can be used in a mold assembly, as shown below.
