Announcing PTC Mathcad Prime 3.1


I am excited to announce our latest release PTC Mathcad Prime 3.1. With the new features in this version, you can better connect your engineering calculations to other applications and processes.

This release introduces a new, enhanced integration with PTC Creo*. Users can embed and edit a PTC Mathcad worksheet directly in the CAD model, at the part or assembly level. This allows PTC Mathcad to automatically calculate and drive parameters to update the CAD model. At the same time, parameters from PTC Creo can be used to drive engineering calculations. This new ability to quickly and easily document engineering knowledge and design intent with PTC Mathcad inside the PTC Creo model provides engineers with a powerful digital engineering notebook.

Secondly, in this release you’ll find a completely rewritten API to integrate and automate PTC Mathcad with other software. The API is more efficient and easier to use, adding important new features such as an event handler and the ability to retrieve and define data in different units. PTC Mathcad Prime 3.1 can now easily integrate with your design software, analysis tools, and PDM systems to support more automated and accurate design processes.

Additionally, PTC Mathcad Prime 3.1 provides pre-built integrations with a variety of third-party tools such as Prode’s physical properties, CoolProp’s fluid properties, and ODBC-compliant databases. Users can also read and write HDF5 file format, or export their mathematical algorithms to drive CAD surfaces through industry standard STL, DXF or IBL formats.

PTC Mathcad Prime 3.1 provides even greater power for users working with large data sets. By making use of the latest in Microsoft technology and 64-bit architectures, data sets are no longer limited to 2GB of memory. Additionally, PTC Mathcad Prime 3.1 is now certified to run on the Windows 8.1 platform, continuing our support for the most popular PC operating system.

Finally, with this release, PTC continues to expand our extensive library of pre-built worksheets. Today there are over 700 worksheets available, covering a variety of real world examples and design problems across mechanical, electrical, civil and structural, chemical, and applied math disciplines, including over 100 free worksheets.

PTC Mathcad Prime 3.1 is the only engineering notebook you need. This new release is the single solution for solving, analyzing, documenting, and sharing your essential engineering calculations and design intent.

Test it out in PTC Mathcad Express or update to PTC Mathcad Prime 3.1 today!

*Also requires PTC Creo 3.0 M030

    PTC may have certified it for Windows 8.1 but they haven’t fixed the problem with multi-line graphics like integrals and matrix brackets showing as dashed lines that occurs with .NET 4.5. PTC’s recommended fix is to downgrade to .NET 4.0 but .NET 4.5 is built in to Windows 8.1 so Prime may work but it doesn’t work as it should do so they shouldn’t really claim that it is certified. What annoys me even more is that they have known about the problem since Prime 2.0, didn’t fix it in 3.0 and still ignored it in 3.1.

    1. The PTC Mathcad team has been working with Microsoft on this specific issue, which was created when Microsoft fixed a bug in .NET 4.5 which then had an undesirable side-effect on how Prime is able to render multi-part text symbols. The most visible impact is that adjacent lines can become misplaced and/or disconnected.

      Microsoft has been working on a solution for us, but they will not undo their original bug fix. The fix they provide PTC will allow choosing between the old and new behavior by application.

      Due to Microsoft’s Dual Branching Servicing Model the fix will need to be deployed in a Limited Distribution Release, which means that Microsoft is addressing Prime’s specific issue in a *hotfix* that PTC will make available to customers. The PTC Mathcad team will test the hotfix once received from Microsoft, and as soon as we validate that there are no regressions we will begin making it available to customers.

      It is important to note that this issue is purely a visual issue and in no way impacts the calculations in Prime.

    I’m a happy Express (ie. unpaid) so I can’t complain -too- loudly, but when are you going to improve the user interface issues? I see all of these advanced improvements that many people won’t use while core interface functionality is still a challenge. Subscript typing, no floating toolbars (especially variables and functions) means that almost everyone that I’ve talked to about Express say they find it unusable compared to MathCAD pre-Prime and so don’t use it. It’s just way too many clicking around between ribbon menus to do the most basic of things. Can you =please= take another look at this? I still use it enthusiastically but only because I’ve forced myself to get used to it – I can’t say I like it…

      Thank you for your inquiry – whatever version of Mathcad you use we always appreciate feedback.

      The floating toolbar functionality you mention is something that we’ve discussed in the past and investigated ways to bring to Prime. It’s true that compared to MC15.0, without the floating toolbars (and using the UI instead of keyboard shortcuts) there is an extra button press to get to operators in Prime. Reintroducing floating toolbars to Prime is in our enhancement database and when customers ask us for it we add their names to that item in the database – that is how we prioritize functionality for inclusion in future versions of Mathcad. As a usability issue it competes with functionality that blocks users from solving math problems and we try to include both math and usability updates in each new release. Unfortunately, floating toolbars won’t be part of the Prime 4.0 release but will be one of the items considered, based on customer feedback, for a later release.

      The discussions we’ve had about this functionality within the Mathcad team have led us in a slightly different direction to solve this UI issue than the solution in MC15.0. I’ll reach out to you privately via email to see if this direction is one that would be appreciated by users who miss the floating toolbars.

    Are there any plans to fix the display of internally created images within Mathcad Prime??

    1. Andrew McGough says:


      We have a couple of enhancement requests for images in Prime. I’ll reach out to you privately via email so I can understand specifically what issue you’d like fixed.

    So, I updated from Mathcad 3.0 to 3.1, however, when I share the documents with my co-workers, who still are using 3.0, they cant open the document, because 3.1 isn’t compatible backwards.
    Can it really be true, that you can’t save it into a compatible format?

    1. Prime is fully backward compatible but not fully forward compatible – currently forward compatibility only works with maintenance releases. For example, Prime 2.0 M010 to Prime 2.0. We have to stack up customer requests such as this with requests for other Mathcad Prime functionality such as equation wrapping and better data visualization when we prioritize what we work on for each release. Our product usage information indicates that when a new version of Prime is released most of our Prime customers move to that version. Forward compatibility is on our list of enhancement requests, but we’ve been working on higher priority functionality to date.
