PTC is going to host a webinar in early September about using templates in PTC Mathcad Prime. (I’ll edit in the registration link when it’s available.) We want to promote how thoughtful template use saves users time and are great for efficiency. We’ll be going into quite a bit more detail than the basics of putting your company logo in the header. While our internal PTC expert presenters will present great insight, you may also have great use cases or experiences that we haven’t even thought of that all Mathcad users could be inspired by!In this thread, please share or describe your Mathcad Prime templates and how they help you: be it function libraries that you regularly reuse, or sophisticated set-ups for accelerating the creation of client reports. (Note: This is a public forum; please don’t share your confidential or critical intellectual property. I may also collate your responses and share them in a PTC.com blog at a later time so everyone can benefit from best practices!)
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 own a perpetual Mathcad 14.0 M020 Single User license purchased directly from PTC. The legacy MCLicense.exe utility authenticates to my PTC account, but the activation request fails with HTTP 403 Forbidden before a license.dat is generated. Since license.dat is never created, Mathcad reports that C:\Program Files (x86)\Mathcad 14\licenses\license.dat does not exist. Can someone generate a replacement license.dat or License Pack manually?My old PC crashed so I am unable to locate the old file.
I have an existing permanent node-locked educational license for Mathcad 15 and am moving Mathcad from my old computer to a new Windows 11 computer. I still have the original product code and existing license file. Mathcad 15 is installed and running to the point where it requests licensing. The Mathcad Single User/Student Get License page accepts my product code but redirects me to License Management, where my PTC account reports insufficient privileges. The Single User/Student Log Case option also does not proceed. I need assistance re-hosting my existing permanent Mathcad 15 license to the new computer and obtaining a replacement license file for the new Host ID. I can provide the old and new Host IDs, product code, and existing license file privately if required.
HiI have a parabola and *n* circles that need to be plotted simultaneously.The idea is that the value of *n* can be changed, and the plot updates automatically without me having to manually add plots.I have managed to plot the circles individually as upper and lower segments—this works fine, provided I can set up the indexing so that it plots all of them automatically.Additionally, I would like to plot the tangent slopes at the intersection points of the parabola and the circles—I have already calculated these—is this possible? My current go to- where i need to ajust number og circles as the number of piles change: Hope someone can helpBest regreads
Hi There , I want to use this function ( filterNAN) , but I’m not sure how it works . I have a nested array f2 . I tried three different approaches but non is working , in f2 I’m using M and sigma they also have NaN in their values , but not all the values are NaN. Regards, Yusra
After a Wibdows 11 update some weeks ago, Microsoft Edge version 150 closes a few seconds after it is opened. This is not a problem for me normaly because I prefer to use Google Chrome. However Mathcad Prime seems to insist on using Edge.I have set Chrome as the default browser and then installed Prime 12.0.0.1 even though I use English as the Prime language. Still no good.Does anyone know how to get Mathcad Prime to use Chrome?Thanks for your help.
Is there any way to send excel data into Matchcad using VBA. I have many claculation work on mathcad but I want excel to be use as an input body which send the specific cell data to a variable in mathcad and the mathcad run the calculation. after that vba send the message to print the mathcad worksheet Example is here to understand Step 1 In excel sheet, we have let say three values in three cells variable with values such as a is 350, b is 505 and c is 900 and so on (actually I have more than 100 values) Step 2 Excel vba open mathcad using COM or API (I do not know the code yet and how to open mathcad from excel vba) Step 3 Excel sent a, b, and c value in mathcad. where many operation are performed such addition, square and many more using these a,b and. Step 4 Excel send signal to print mathcad and then close the mathcad worksheet. Note: Please note the actual work is much more complicated it has atlead 60 pages of calculation in mathcad and more than 1
Hi There ,I have two functions are exactly the same but in two different sheet in the first sheet . it works perfectly and I’m getting the expected answers for f2In the second sheet it doesn't work and I suspect the reason is M has different arrays . How can I fix this function : the error says : This array index is invalid. The index must be an integer, not less than ORIGIN, and not greater than the last element."I can’t attached simplified sheet even in zip file. I hope you can help Thanks in advance , Yusra
Hi. I am trying to use an advanced list box to select a beam section from the first column in a matrix that I can then use to lookup related properties further on in my calc sheet. The problem I have is that the selection does not get parsed to the output variable. Any help with this would be appreciated, I can’t seem to find anything useful online, but I am clearly missing some detail.Here is the list box code and MathCAD file attached. // TODO: Add your initialization code herefunction ListBoxEvent_Start(Inputs, Outputs) { // TODO: Add your code here};function ListBoxEvent_Exec(Inputs, Outputs) { // 1. Clear the list box contents FIRST to reset it ListBox.ResetContent(); var options = Inputs[0].Value; // 2. Loop through and add the strings for(var i=0; i < options.length; i++) { ListBox.AddString(options[i]); } // 3. Set your output Outputs[0].Value = options[ListBox.CurSel()]; //Outputs[0].Value = ListBox.get_text(ListBox.CurSel());};function ListBoxEvent_Stop(Inputs,
What do I use to i stall mathcad
Hello,I am new to developing custom functions for Mathcad Prime.I already managed to create a working custom function in C, but I still cannot understand how to do the same in C++.To be honest, I do not understand the internal structure of Visual Studio C++ projects yet. I am learning step by step and using AI to help me understand the code and project structure.My goal is to move large engineering calculations from Mathcad into C++ DLL libraries. I hope to use AI to help convert my Mathcad algorithms into C++, but first I need to understand how a working C++ custom function project is organized.At the moment I cannot even create a very simple function like:int add(int a, int b){ return a + b;}I am not asking anyone to write my project for me.I would simply like to have a minimal Visual Studio C++ project that builds into a DLL and is recognized by Mathcad Prime. Even a project containing only one simple function would be enough.Once I have one working example, I believe I will be a
I have purchased a new computer because my old computer can not be updated to windows 11. I have Mathcad 14, #15, Mathcad Prime 3.1 on my old computer. I want to put them on my new computer and my question is whether I can copy the files to a usb drive and put them onto my new computer? Or cand is download the from and old download file? Or do I new to get a new download from PTC?Your assistance would be greatly appreciated.

Hello, I'm having trouble developing a loop that includes break and return statements for buckling analysis. I'm also having trouble generating a combo list for the K values.
I need to evaluate anchored walls, according to FHWA Circular 10, for various strata, but I've had problems with the definition of a vector i. This new version of Circular 11 changes the definition of a vector, so could you help me with this problem?Regards.For loop and return for a vector i
We run FLEXnet on our company license server for Mathcad licenses. Currently on version 12. Our Mathcad license file has both permanent and subscription licenses of Mathcad Prime (and 15) in it. When a user runs Mathcad, the server first assigns a license from the permanent pool. If that pool fills up then it assigns a license from the subscription pool. The problem is when a user receives a license from the permanent pool, the license type shown within their Mathcad software says Home Use when it should say something like Commercial. This results in certain calculations being inaccessible and causing errors in their worksheet. But if a user receives a license from the subscription pool, the license type is shown as Subscription which should be fine.I would like to know why our Mathcad license server is serving us Home Use licenses instead of the commercial licenses we paid for, and how do we fix this?
Need PTC to provide Mathcad 14 license to activate Mathcad on Win 11 system
Have just paid for a licence to upgrade from MathCad Prime Express 12.0.0.0 to the full Prime version, hopefully 12.0.0.1. Following "Options|Get Licence" I have encountered a prompt asking for my product code. Where can I find this? Do I need to log in to the Fullfillment portal? Does it use the same general ptc account? It didn't recognise mine. When looking for help I am told I don't have access permission and haven't paid for that level of support. Elsewhere it says I have "Gold" level support. I an angry that you have now pointed me to a public forum where I can't post useful identification data. What a horrible mess. Can anyone help me get into contact with someone at PTC?
Hi, as you can seeat the bottom of the picture, when evaluting the function “Iresonance”, instead of replacing the variable with the actual, it gives “function” in the result, but the function “wresonace” is already defined. How to subtitute it? Thanks
Hi, I’m just trying to get the real and imaginary part from a complex number, but the result is just not right.
I can not contact a support department "access denied" to get a new licence file to install my Mathcad 15 on a new computer. Could you help me. I am desperate ! J.P. Collette jpcollette@walopt.com
