HI, First time user of the GD&T advisor, trying to add a position tolerance to one half of a hole pair (for a shaft) and a second position tolerance to the second hole of the pair, A simplified version of my part is shown in the attached image. Currently running Creo 11.0.2.0 Hole was modelled as a single hole for both pairs. With the model setup like this I am unable to select either the right or left hole to assign a tolerance. Am I missing something here or is the only way to get this working by modelling this as 2 separate holes? Thanks 

Whilst writing a string replace function for Mathcad Express, I found what seems to be a problem with the string function search.   I wanted to check a string for the existence of the Unicode characters for 11 (↊) and 12 (↋) in the duodecimal system ... and it found them everywhere even when they weren't there at all.   Has this been noticed before?  Have I made some kind of error or unwitting assumption?     Cheers,   Stuart   (The simple recursive algorithm shown above is O(n) and only good for strings shorter than about 4000 characters (ie, under Mathcad's recursion depth limit.   A slightly more complicated algorithm would use a binary-division algorithm to reduce the recursion stack to O(log n), which will handle much longer strings)

If there is a way to display the values of variables inside a block in mathcad 15?

This file is in MathCAD 9, but I'm experiencing the same issue in MathCAD 10. I believe MathCAD is misrepresenting the units. See attached. "Hmp" and "TH" have the wrong values when comparing with example 11.2 at the bottom. I rewrote them as H and T next to them. I substituted "m" and "Ump" for the actual values of 100000 and 1035 and the answers came out correct. So, something is wrong with how "m" and "Ump" are represented.

Hi,Can anybody solve equation ? Solution is x =1, but Mathcad doesn't see this solution ...  

I'm trying to pass on a variable as a string to another mathcad Prime sheet.  VAY is a number defined above in calculations within the sheet.  I don't want the evaluated value but the variable itself.  There should be a function to do just that.  See screen shot.

I am working with Creo 8. I would like to implement a dialog with tree view in it. The tree has 3 columns. I have spent few of hours trying to understand API to create and populate tree. But not able to figure how to do it. With C++ I wasn't even able to add node to tree. With C I could add node but not able to figure how to add column. If anyone has tried this already I would appreciate the help in from of sample code. FWIW - For C I have following working code to add node -     auto status = ProUITreeColumnCreate("dialog_material_assign_assembly",                                        "MatAssignTree", nullptr, L"Test", 10,                                        PROUITREECOL_LEFT);    status = ProUITreeNodeInsert("dialog_material_assign_assembly", 

I had to change to a new Computer because of updating to Windows 11. Content drive C: has been cloned. It is not possible to get the license again. Mathcad cannot be used. What can I do?

Whenever I stop working on creo for a period of time or the network pauses creo becomes unresponsive and shows as not responding - this happens quite often and the only way to fix it is to end the process in task manager and restart Creo.Any ideas on how to fix this would be appreciated.

We have just installed Creo 11 in our office and have now found the it is stripping the Mapkey from the Config.pro files and placing them in the App data setting folder as a new Mapkey.pro.   This is a big problem for us....   We have multiple start up shortcut that point to different folder that has different Config.pro & search.pro files depending on the task we are working on, and each Mapkey in the config.pro points to a different file location to set the working directory.   I don't have a problem with the Mapkey being placed in a separate file, but I hope we have the option in the config file to point to a different location so we can mange the different options.   Peter

Hello PTC community,   Im contacting you regarding a reoccurring issue we've encountered with a license on a specific Host,   Since 25.08.2025 we installed Mathcad License(Prime 6 which is compatible with MathCAD 15) Locked version on our host.    The license activates the software and works as intended for couple of days, after that it's getting deactivated and has to be activated again (Activated 3 times already). We've followed the procedure as shown in PTC Knowledge Base and it has worked successfully on multiple other hosts. Only on this case we encountered this issue.   Kindly advise how to proceed & let us know if more information is needed.   Best regards

I have an old copy of Mathcad 15 and Prime3.0 installed on a Windows 10 computer which was purchased 2/8/2014 . I need Windows 11 licenses for both as I purchased a new computer.

Hi, I want to understand what ways you have employed to distribute Creo Parametric config and setup files at an enterprise level to end users. We use SCCM to distribute / deploy base Creo Parametric application, but to distribute config and setup files, we use windows batch script that gets invoked once a day at end users' machines.  The setup files are kept at few regional servers (as repositories) and the batch script copies (robocopy, syncdirs) these files into the end user's device. We have not opted for packaging Config and setup files through SCCM as these files are changed or new files are introduced frequently.  And the need is to get them distributed as immediately as possible. Our requirements: Config and Setup files are maintained at one network location (mother repository).These files should be replicated to Regional specific repositories.The files then should be pushed from each Regional Repositories to end users located in respectiv

I am using Mathcad Prime Release 10.0 and Datecode10.0.0.0My company uses Python scripts to extract Mathcad Prime data to Excel spreadsheets. The Python code uses the MathcadPy library to extract data to the spreadsheets, but I am continually getting errors when running the code. I have also seen the error popup when running Mathcad Prime normally.We create a folder structure of Mathcad Prime files, using relative links to point to the folder/file at the next level up. We have a number of Mathcad sheets in the same folder and they all point to Mathcad files at the directory above , to make a make-shift library of electrical parts/parameters for our application.I will randomly see the error pop-up when accessing these files. It is also random, and there is no predictability to the error popping up.Here are the errors that I faced"An unhandled exception occured. See .log file"Exception data:System.Exception: Lisp applying: CallNodeCallback {global} to Engine.NodeCallback, 1419, NODE_READ

Hi, I've recently generated some geometry in Creo Parametric 11.0.0.0 on Windows 11, but I can't export it to a different file type for use in a different program. I've tried STEP and Parasolid filetypes, but both export as empty files. What is happening?Here's a photo of the file sizes, something is clearly wrong. Any help is appreciated! I attached the file to this post. 

I’m trying to create a pen table to automatically print in black and white through a distribute patch. I tried several materials but it doesn’t work, the copy comes out in black and white. Can anyone help me with this? How can I automatically print a PDF in black and white using distribute? Thanks in advance for everyone’s attention!!

Hello All, I have attached P10 sheet and an Excel sheet I am reading from. Many thanks to Werner and Stuart for helping me get this far. On page 12 of the Mathcad sheet, you’ll see the results of the axial forces and moments imported from the attached Excel file. On page 13, I’ve listed a couple of questions I need help with:1 How do I extract from the [TC axial Comp] forces of the panel forces (e.g. TC1, TC2, TC3, TC4, .... ) and place them into a vector labeled TC.Panel.Axial.Compr?2. How can I extract the [TC axial Comp] forces at panel points (TPP#), such as TPP3, TPP5, TPP7, TPP9, … and place them into a vector labeled TC.PP.Axial.Compr? Regards,Sam 

i have been a long time user of MathCad, strongly prefer the old, non prime versions.  Thinking of trying Prime once again, in case MathCAD 15 no longer can be made to work.  When to activate a newly downloaded, properly assigned locked licence, Prime does not seem to have an activated licence.  For example the watermark is there, the activate button is live, and not all functionality is available.  I'm not sure what to try next.  I've verified the MAC ID, downloaded new licence files a few times, tried on Windows 10 and windows 11 PC (of course properly assigning the MAC is in licence manager).  I also opened a ticket for support, that I have paid for for years and years and years, and have enjoyed no reply so far (about a week of waiting). Any tips?

Hello All, I have been manually inputting values from an Excel file into a table in Mathcad P10 sheet. I have attached both files. Is it possible to automate this process? I am interested in getting the values I highlighted in yellow in the excel sheet. Regards,Sam 

New to this Mathcad Prime here. Version 10.0.  I converted a sheet from Mathcad 15, In the converted sheet, every time I change the inputs I get question marks on the outputs and have to go back and manually type the uints over again. Is this a bug or can I solve this somehow. Thanks.

Hi All,Would someone be able to tell me how to delete a row or column from any table in drawing mode? I've been looking for about an hour and still can't find a way. Appreciate any help anyone can give. FYI, I am currently using Creo 2.0.

Could anyone suggest how I can setup a function within Mathcad to resolve the attached expression where I am looking to find theta? 

Are you frustrated with limited functionality when you use PTC Mathcad Express? Watch this on-demand 60-minute in-depth session made just for Mathcad Express users on how to get the maximum benefit from the PTC Mathcad experience.   Also, we have a new Mathcad worksheet available for download that gives an in-depth comparison between Express's capabilities and Mathcad Prime's capabilities. It was ghost-written by popular Mathcad author Brent Maxfield, so Mathcad Express users will learn a lot about what they're missing by not upgrading to Prime.

I'm looking for guidance regarding how to set up a heat exchanger component in Creo Flow Analysis (CFA).  Are there any examples, tutorials, or online help available?  I'm not finding anything. Thanks! Mark  

Reference from topicI've been fighting with this issue for years now, in my case it was win32_gdi -- once I replace it with opengl it worked like a charm!!May I ask how does one start this Information Window, and where is this file support.inf.1 located?Thank you again Remy, you made my day!!!
