Did You Know? Creo 3.0 Enhancements: 3D Thickness in Creo Parametric

“In Creo Parametric, you now can build a 3D thickness check directly into your design process,” says Russell Hsu, product manager. “In a few simple steps, you can identify critical thickness areas in your model so that some necessary changes can be made before review.”

Thickness measurements can be crucial to someone working with tooling or injection mold design. Miscalculate, and you can end up with short shots, that is, molds that don’t fill completely.

In the past, you’d have to take multiple measurements or use add-on software to ensure your wall thicknesses were reliable. But with the new Measure 3D Thickness tool, you can quickly check where you model meets or fails to meet your minimum and maximum thickness requirements.

Here’s how it works:

  1. In Creo Parametric, click the Analysis tab.
  2. In the Model Report group, click Thickness to open the Measure 3D Thickness dialog box.
  3. Type your minimum and maximum thickness values.
  4. Click Compute; the system then highlights in purple those areas that violate your minimum specified thickness. Red areas exceed your maximum value.


Rotating the model, you’ll see minimum (purple) and maximum (red) values were violated within the interior of the model.

That’s all there is to it.

To see a short demo, check out the video tutorial on the PTC University Learning Exchange (“Check for 3D Thickness”). Note that you may need to create an account if you don’t already have one. The good news is that it’s free, and after creating your new login, you’ll find hundreds and hundreds of in-depth demonstrations and tutorials for PTC products.
