I am facing an issue in Creo Simulate 9.0 while performing a Random Response Analysis on a large assembly. The modal analysis runs successfully up to 2000 Hz and extracts approximately 250 mode shapes from a mesh containing around 280,000 elements. However, when I proceed with the Random Response Analysis using these modal results, the solver fails with the status "Run Failed". No specific error messages are reported in the log files, making it difficult to identify the root cause. The analysis is being run on a high-end workstation with 256 GB RAM and ample local disk storage, so system resources do not appear to be a limitation.What is interesting is that the Random Response Analysis completes successfully when limited to only a few modes (for example, the first 6 modes). Has anyone experienced a similar issue with large models or high mode counts in Creo Simulate? Are there any known limitations, solver settings, memory requirements, or additional diagnostic logs that I should inves

It seems that my Mathcad version I have just downloaded Is Mathcad express Prime and not the Mathcad prime. Please check.

Is it possible to use the home use license with an extension? We have Creo design advanced professional licenses, but cannot use the manufacturing extensions for home use. Myself and other employees have hobbyist CNC machines and were curious if we could purchase a CAM extension to use with the home license?

Tried to research this and found other posts but no results listed.  Using CREO Parametric 10.0.4.0In an assembly, I have 10+ components assembled and always try to fully define the constraints.  As I am adding additional components and constraints towards the end of the design (hardware) I start getting "Confirm Package Reference" which to me indicates another assembly component is not fully defined.  I can click "Use Ref" and move on but want to resolve the unconstrained component that I am assembling new parts to. Looking back at the assembly tree, I see component #10 has a small box indicating it is not fully constrained.  I click to edit constraints, and the Set Status says "partially constrained".  Yet I have three constraints (coincident/distance/distance) that should fully constrain the part/subassembly.  So I uncheck "Set Enabled" and create a new set.  Using similar constraints, I get the status to read "Fully Constrained". Close out th

How can I make sure that e_max is added correctly … non of them has units , but still getting this error Thanks Yusra

Hello everyone!I am trying to create a pin constraint regarding the rotor of an electric motor. As expected I want it to only rotate around itself. I am attaching the pin constraint I have set and I can’t find the issue with it…Any help is really appreciated!This picture shows the axis alignment. This picture shows the translation 

Hi,Another Odesolve problem with an error I cannot identify. Google AI says its a syntax problem but I am damned if I can see it.Any assuistance would be appreciated.Regards, Ross

PrimeConnect C++ -> Prime -> C++PrimeConnect is a pair of C++ solutions/projects.One writes a *.mcdx Prime output file fully described by C++ syntax that encapsulates the mathematics of a Prime Worksheet.Two reads a *.mcdx Prime input file where all evaluation regions of a Prime Worksheet can be assigned to C++ variables in one line each.They both work on the underlying feature of *.mcdx files that are a collection of zipped XML files.  In the case of Prime text regions zipped up zipped files of text.The underlying XML text manipulations are handled invisibly by PrimeConnect. User of C++ can concentrate on the mathematics when writing a *.mcdx file.  User can concentrate on what are all the evaluation regions in a Prime worksheet are and assign them to C++ variables.Writes Prime v10 files, Reads Prime v9, v10, and v11 files without varying C++ code just point the C++ to a *.mcdx file.Both Microsoft Visual Studio 2022 C++, and Embarcadero RAD Studio 12 projects are available.  The

I'm getting an error when running tasks in CREO: ERROR CODE:3 (SUBCODE7). I've already contacted NVIDIA; we've updated the driver, rolled back to older versions, and tweaked the graphics card settings, but the error keeps coming back. The card is a Quadro P400.   

I have Nonconformance Object, I need to get Nonconformance Review from Nonconformance object.Is there any api to get Nc Review or navigate Api will work.

Is there any API to bring Nonconformance Review from Nonconformance?

during the import of a STEP file. After opening the STEP file and confirming the import as an assembly, some of the imported components is not correctly recognized: the square icon, which indicates that the component's constraints or degrees of freedom have been correctly identified, does not appear in the Component Tree. By opening the Edit Constraint Definition dialog and simply clicking OK, without making any changes, the system immediately updates the component status and the square icon appears in the Component Tree. This behavior demonstrates that the recognition of constraints (or degrees of freedom) is not performed automatically during the import process, but only after a manual user action. We therefore request that, once a STEP file import is completed, the software automatically recognize and update the constraints for all imported components, eliminating the need to manually confirm each individual component.

About Mathcad 14. I have just installed it to a new PC with Windows X11. When I try to run it, it asks me to run the license assistant. I do it, I get a web page asking to create a new account (although I already have one), so I create a new account, then nothing. Thanks for helping me. Regards, Michel Bonnardeau

Hi there, I don’t know why it shows this error here . I used the same function in another sheet and it is working Regards,Yusra

Hi, In Creo 3 I was able to add a dimension to a 2d drawing and while the dimension was still highlighted red...I could change the font, color and size.  We then jumped to Creo 7, and it seems this no longer works. We are now on Creo 11, and it still doesn't work. I can change the font, and the size..but color does not stick if I just created the dimension. If the dimension is already existing, and i click on it….. i can change the color.  I want to change the color on the fly. I am trying to create a mapkey to do this, but i cannot get this color to change if I try to run the mapkey on the fly, after creating the dimension. (with the dimension still highlighted) If I run it on an already existing dimension, it works fine.What am i doing wrong? see recording   

Hi everyone,I am working on a cabling harness design in Creo Parametric. I successfully created a main bundle using the "Along Path" option. Now, I need to create a Branch Bundle that splits off to the right from this main thick bundle.When I select Bundle > Create > Branch, the Menu Manager asks me to "Select 2 items." and forces the selection filter strictly to "Location".However, when I try to select the required locations, it does not allow me to complete the selection or choose the second point correctly to define the branching direction along the network. The network paths for both the main trunk and the branches are already defined, and the wires are routed.Could someone please guide me on the exact selection sequence or share what might be blocking the second item selection in this step?

Hello! I have been trying to get the free version of Mathcad, but I run into a problem. I had the free 30-day trial on my previous laptop, and now Im looking for the free, express version. I downloaded from the Download .NET 8.0 page the .NET Desktop Runtime 8.0.28 and restarted my laptop, but when I press Download again, it takes me to the same page with .NET again. 

Hello! I ha previously downloaded the mathcad trial, then used the free, limited version. I have since then changed my laptop and am trying to download it again on my new one. I filled out the form for the trial/free version, but I have not received any email back (this was a few days ago). I also tried to download the program from the "download" shortcut, but after I restart my laptop and press download again, it keeps taking me back to the same page with the downloading links. I tried .NET Desktop Runtime 8.0.28 and .NET Runtime 8.0.28, both the x64.

We just recently switch from Creo 9 (because of end of life) to Creo 12 and are having major problems when importing sheets from other Creo drawings into a new Creo drawing.  Continue to get random errors, but the most common error is "Unable to merge. Target drawing contains incompatible elements. Please contact Technical Support." Never had any problems with Creo 9.  I can open a Creo 9 drawing in Creo 9 and import sheets without any issue.  Open the same drawing in Creo 12 and try to imports sheets and after 2 or 3 sheets it starts throwing error messages and will not import any more sheets. Anyone else have this issue? Contacted PTC support over a month ago and still no answer. Thanks

Hi everyone,We are currently developing a Creo TOOLKIT-based connector that synchronizes Creo models with an external system.As part of the synchronization workflow, the connector needs to detect changes made to the model (such as newly added parameters or geometry modifications). Before these changes can be synchronized, the model must first be saved so that the latest state is available. To avoid requiring users to manually save after every change, the connector automatically saves the model when necessary.However, we've observed that once the model is saved, the Undo history appears to be cleared. As a result, the user can no longer perform undo operations on the model that were enabled before the save.In some other CAD applications (e.g., Autodesk Inventor), saving the model does not clear the Undo history, allowing users to continue using Undo even after an autosave.I'd like to understand whether this behaviour is expected in Creo.Is it by design that File → Save (or ProMdlSave())
