Mathcad

Hi everyone,I’ve made a small free Windows utility called **FyMathcad** for PTC Mathcad Prime.The first tool I implemented is something I’ve wanted for long Mathcad worksheets: an automatic **Table of Contents generator**.FyMathcad can:* detect level-1 headings in the active Mathcad Prime worksheet* preview the headings and their page numbers* insert or update a Table of Contents* automatically number the heading captions* create clickable links from the TOC to the corresponding headings* adjust page numbers after inserting the TOC* create a timestamped backup before modifying the worksheetThe workflow is simple:1. Open and save the worksheet in Mathcad Prime.2. Run **Print chapters** if you want to preview the detected headings.3. Run **Insert TOC** to generate or update the TOC.The project is available here:https://github.com/spectereye/fymathcadIt is free to use for both personal and commercial work.This is the first tool in FyMathcad, so I’m also interested in ideas for other small

Hello all,Please, is there any way to generate a table of contents in PTC Mathcad Prime 3 ?Thanks in advancedBest RegardsRedwane

Hi,I am trying to solve variable T_H, starting with a guess value of for example 10 kN/m. With this value z(x) is solved using Odesolve, then T_H is evaluated and a new value of 135 kN/m is found. This iteration continues until the correct value of T_H is iterated. Could someone please guide me on how to correctly implement this in Mathcad?  

PTC hosted two live webinars about Mathcad Templates back in September 2026.“Build Once, Reuse Always: Mathcad Templates” promotional imageYou’ll learn about how Mathcad templates work and why you’ll want to use them. Our PTC technical experts shared best practices to get the most out of templates, going beyond the basics. We strongly encourage beginner Mathcad Prime users to watch this replay to accelerate your Mathcad adoption and greatly speed up your ability to make new projects in Mathcad. We published the recording of the September 10, 2026 session by Ioana Cernat; it’s now available here. You will also find the presentation materials available for download (several Mathcad files and a PowerPoint / PDF presentation), as well as written responses to the live Q&A we had from the sessions.

I want to scale M(x) equation by a scalar (0.805). Is there a way to do this without making my expressions unitless? After searching online for info about the error statement, I could not find a workaround. Note: whenever 0.805 is not applied to M(x) the equation graphs properly. M(x) is defined in kip-ft.

I would like to READTEXT from text file which would form a two-column matrix.  That part is easy.  Then I would like to copy the contents of the first matrix to a second matrix, then use that second matrix for other purposes, but unlinked to the first matrix.

It is said that in order to run PTC Mathcad Prime, you must have the latest Microsoft .NET Desktop Runtime 8.0.x package for Windows x64 installed on your computer. At the same time .NET 8 end of life (EOL) is November 10, 2026 – after this date, Microsoft issues no further security patches or bug fixes. EOL means real risk: unpatched vulnerabilities, compliance failures... Am I missing something? It seems rather serious. It looks as if I have to skip the latest version. Does Mathcad Prime v12 work with .NET 10?

Hello. I'm using Mathcad Prime 10.0.1.0 and I'm having trouble saving to PDF. Neither the built-in PDF export nor Microsoft Print to PDF works. I found this thread, but the solution seems to apply only to version 12, not version 11 or earlier. Can anyone help? https://community.ptc.com/mathcad-7/save-as-pdf-or-print-to-pdf-causing-unexpected-error-mathcad-prime-12-175521

Hi All,Can someone please help me fix this corrupted file?  I have spent a couple of hours working on it, and suspect it is a font size error or something. (see attachment)Thanks in advance,Brett

Mathcad 12, Product Code: JG120411KU0993 HHSN HMJB Installed on new computer but need activation code to run. Installed on ASUS Laptop with windows Home OS. Purchased in 2012, believe was the date. Need to get product activated, Jim English

Hi there , I don’t know why I’m having this problem with Mathcad sheet . I used to convert it easily , but it is not working anymore . Does anyone know the reason?Thanks Yusra  

Was wondering if there is a way to mod or get mathcad to add geometric algebra (or Clifford algebra diff name) into mathcad. THis would include multivectors, the wedge product and the geometric product? Not sure if there is any modding of mathcad at all for reference  

My employer purchased mathcad for 3 of us, however despite IT saying mathcad is installed, it is only the trial version. I need to get the product key/code so I can utilize the license we paid for. To date, I have never been able to use the purchased version of mathcad and it was purchased about 3 months ago. please assist.

I cannot print to PDF when text contains Calibri font type. As soon as I change the font type to something else, such as Arial, the file will print to PDF without issue. I and several associates are encountering the exact same issue. We are using MathCAD Prime 12.0.0.1. Is this a known issue? Will it be fixed in a future update?

Hello. I am a student at Næstved Zealand and we use the free trial version of mathcad here. I have gotten a new computer and need to download it again but i am not able to. I keep filling out the blanket where it says: Free 30-day trial of Mathcad engineering calculations software. But when i finish it says i need to wait hours to get an email with a download link. But i never get this download link i have waited days and tried over and over. Is it possible to help me please?

Is there a way to automate the collapse or expansion of areas depending on user input above in a worksheet?  Maybe by use of JScript or Python?

I’m trying to develop a robust approach for analyzing different configurations of a four-bar mechanism in Mathcad Prime. I’m looking to determine the corresponding angles for the crank, coupler, and rocker based on the mechanism dimensions and input configuration.I’ve tried a few different approaches and, interestingly, I’m getting different results depending on how I formulate the equations. I’m not sure if I’m missing something fundamental in my approach or perhaps overcomplicating the worksheet.I don’t work extensively with Mathcad Prime, so I may be overlooking a reference, function, or recommended approach that would make this easier. I’m also finding it a little difficult to identify the right reference/example for what I’m trying to achieve.The ultimate goal is to build one generalized worksheet that can handle different types/configurations of four-bar mechanisms under the same set of equations, rather than creating a separate solution for each mechanism.Any suggestions on the

I cant get the license to work in my MathCad for the trial

I uploaded some Excel files into M365 to convert into Mathcad Prime 11. The files created did not open in Mathcad Prime 11. Can anybody please help. Please see attached zip file.

This month’s challenge is about tautochrone curves and isochronous curves. They are very similar. Both involve placing an object on the curve and allowing it to slide without friction. With a tautochrone, an object placed at any point on the curve will take the same time to slide to the bottom. With isochronous curves, objects allowed to slide from any part of the curve will have the same period of oscillation. You can think of the tautochrone as “half” of the isochronous curve, as it is only concerned with how long it takes the object to reach the bottom.In this scenario, the “top” of the tautochrone curve is at a height of 10 meters on the left side. The end point is at ( 0, 0 ). (The “top” of the isochronous curve on the other side is 10 meters on the right side.) Design a curve such that an object placed at any point on the curve will take the same time to slide without friction to the end point under the effect of uniform gravity. Examples of three possible solutions from Creo 13.

I have a student version of Mathcad 15 that I was using years ago.Now, I want to install it on a new laptop and open my old files, but I receive an error from remote server during the installation.Can anybody help me with this process?Picture below shows the error message that I receive while trying to install the software. Thanks, 

I do not recieve e-Mail from PTC when it says to go to my email during the acquisition of the 30 days trial license.

Hi, I have issues to get a license file. I can't run the software.I get: The remote server returned an error 403. Forbidden Can you help? Thanks Arek
