With the release of Creo Parametric 3.0 M030 , we enhanced the integration with Creo Mathcad Prime 3.1 so that you can embed a PTC Mathcad worksheet directly in the CAD model. There are several benefits.
In this post, we look closer at that last item, driving parameters in the CAD model. There are three steps to linking PTC Mathcad to a Creo Parametric model and using your worksheet calculations to automatically set the parameters in your model geometry.1. Embed a PTC Mathcad Worksheet.
Once you’ve upgraded to Creo 3.0 M030 and PTC Mathcad Prime 3.1, you’ll see the PTC Mathcad icon on the ribbon interface under the Applications tab. To embed a worksheet, just open an assembly in Creo and then click
Applications > PTC Mathcad > Insert Worksheet.
Now you can create the calculations that you want to drive your geometry. You’ll see a sophisticated example below, but any elaborate relation you set up in Creo is a candidate for your worksheet. You’ll select regions, give them a name, and then save and push the results to Creo Parametric.

With output regions defined, you can create relations in Creo Parametric Relations dialog box.

PTC University has an online tutorial to show you how it works. An instructor takes you through the steps demonstrating how to designate output regions in a PTC Mathcad worksheet, and then create the necessary relations in Creo Parametric.
If you’d like to see more, I’d recommend a visit to PTC University Learning Exchange for the companion tutorial Link PTC Mathcad Prime 3.1 Input Regions to Creo Parametric Parameters. You’ll need to create an account—but it’s free and there are 700 more tutorials just like this one waiting to show you how to use PTC products effectively.
For a more complete education on linking PTC Mathcad Prime 3.1 with Creo Parametric, you can find an excellent tutorial here. It includes all the steps you need to embed the worksheet, link input regions (that is, let your geometry determine the values in your worksheet), push results to Creo (that is, use worksheets to drive the geometry), and more.
