Enhanced PTC Creo and PTC Mathcad Integration

** Guest Post by Andrew McGough**

PTC Creo and PTC Mathcad are highly complementary products when used in the engineering design lifecycle of a product. PTC Creo is used to capture the product design, PTC Mathcad is used to capture the engineering knowledge that details why the product needs to be designed the way it is. It’s a product that deals in numbers, and numbers ultimately drive design.

PTC Mathcad and PTC Creo Integration

There is great value in using these two software packages together within the design process. A PTC Mathcad worksheet can be used to determine and record engineering calculations that apply to specific design decisions that can then be reflected in the PTC Creo model geometry or simulation data. The worksheet and the model can be stored separately in PTC Windchill. However, an integration that brings the engineering notebook capabilities of PTC Mathcad within the PTC Creo world is something that would streamline the process and introduce a number of time saving ease of use benefits.

In PTC Mathcad Prime 3.1 we will be introducing a new, enhanced integration between PTC Creo and PTC Mathcad. PTC Creo 3.0 M020 users will have the ability to embed a PTC Mathcad Prime 3.1 worksheet directly within their model. This PTC Mathcad worksheet can be opened directly from inside the model view and then edited and saved within the model itself. In this embedded use case, the Mathcad worksheet is stored within the part or assembly it supports thus removing the need to control and manage two different files. This embedded PTC Mathcad worksheet can be used as an ad-hoc scratch pad to derive off the cuff calculations or as the source for specific geometry calculations for the model. It can also be used to document engineering knowledge directly associated with the model itself – including company IP or regulatory information. Again, all this information in the PTC Mathcad worksheet is saved and accessed from within the PTC Creo model. This means that where the model goes, the engineering knowledge goes too.

To further augment this integration we’re introducing the ability to share data between PTC Mathcad and PTC Creo using the parameters table within PTC Creo, an interface for data with which PTC Creo users are extremely familiar. Specific parameters within the embedded PTC Mathcad worksheet can be tagged as inputs or outputs. Once the embedded worksheet is saved, those parameters will become available for use within the parameter manager of the PTC Creo model in which the worksheet is embedded. There they can be used within the model in much the same way native PTC Creo parameters can be used.

This enables two powerful use cases we call Analysis Driven Design and Verification and Validation. In Analysis Driven Design, the comprehensive math functionality of the embedded PTC Mathcad worksheet can be used to derive critical design parameters that can then be tagged as outputs from PTC Mathcad to PTC Creo. Once in the parameters table in PTC Creo, the relations editor can be used to relate those values to specific dimensions in the model. In Verification and Validation, the embedded worksheet can be used to validate parameters from the model itself. Inputs to PTC Mathcad from PTC Creo are sent to the worksheet to be validated against user defined sets of equations to ensure they fit within whatever criteria they need to adhere to.

With the embedded PTC Mathcad worksheet, PTC Creo users will now have the power of PTC Mathcad’s calculation engine and documentation features immediately at hand within the model. Data between the products can be easily shared using existing UI features. PTC believes this enhanced integration makes for a more effective and efficient design process which in turn leads to better product design.

    I thought there was already an Integration between MathCAD and ProE (Creo). What’s new here ? Is the Integration leaner and more efficient as well as new functionalities ?

    How does that all check in to Windchill ? WIll the MathCAD file be a reference to the Creo file ?
    Can a same matchcad file be used for several CAD file. Eg I have some formula and Parameter in the MathCAD file stored in Windchill as a reference calculation sheet. Everytime I Need to design Validation/calculation to prove my new design, can I call that MathCAD into my Creo file, run the calculation and if OK, I can check the Creo file in Windchill and the design approver can see that the Creo file was created and validated with the released/approved mathcad calculation sheet. Of course the Creo models must be done in a standardized way to ensure it is working with the Parameter in the mathcad file.

    This is something we currently manage in Excel and some Java…….

    Best regards

      This new integration is separate from the existing Mathcad Analysis Feature. The MAF will continue still be shipped and supported alongside the new integration as the MAF serves some specific work flows.

      The new integration will allow a Creo user to embed a Mathcad worksheet directly into a Creo part or assembly. The embedded Mathcad worksheet can be new (blank) or a copy of an existing worksheet. Once embedded, the worksheet will ‘live’ within the Creo model – it will be saved as part of the Creo file. It can be opened and edited at any time – it will open in an instance of PTC Mathcad Prime so users will need that installed on their system. It’s not a separate Mathcad file – it can only be accessed from within Creo. This embedded worksheet allows users to capture engineering knowledge specific to the Creo model, document that math in a simple and easy to read fashion, and keep it with the model.

      Furthermore, within an embedded Mathcad worksheet the user can define Inputs to Creo and Outputs from Creo. When the worksheet is saved, this data will become available within the parameters table of the Creo model. With it integrated into the Creo work flow like that the relations editor can then to be used to either drive dimensions in Creo from parameters in Mathcad or send Creo parameters to Mathcad to be analyzed in the worksheet.

      In the first release the embedded Mathcad worksheet parameters within Creo that are tagged as Inputs or Outputs won’t natively be available within Windchill but the Mathcad worksheet will be checked in as part of the Creo file, so there will only be one file to manage.

      If you have any more questions on this new functionality, please don’t hesitate to ask.
