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?

When a model is open, it's a great convenience to be able to open technical drawings with the same name as the model, filtered by their location within the same folder.

I was downloading the student version of creo for my class, but I dont see any License folder under the ProgramData/PTC file.

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 am using Creo Parametric Release 11.0 and Datecode11.0.7.0 Some times creo doesnt save changes made. Before I quit out I regenerate and save (Ctrl + R, Ctrl + S), and the save seems to go through. When I open the part or assembly at a later time, the changes made are not saved, and I have to redo geometric changes, constraints, assemblies and such. At times, the work done, and changes made are saved as expected, at times, almost at random, the work done, and changes made are lost. I guess this is user error, and not software related, but I havent had any luck in trying to troubleshoot online. I work locally, and not towards a PLM or PDM software. Here are the errors that I faced: No error messages, the only popup is the classic "If you quit without saving ... yada yada", which pop ups even though no changes have been made. This message pop up when exiting the client, not when exiting the model / assembly.

When will the human model versions of GB/T1000-2023 and ANSUR II be available in Creo manikin Extension?

When the Drag Components command is used in a multi-level assembly with mechanism connections, opened through Windchill PLM, the user is prompted to select either Check Out or Continue for the affected CAD objects.Selecting Continue at the top-level assembly does not apply the same selection to the subassemblies and components involved in the mechanism. If Continue has not been selected for any affected object at a lower level, the Drag Components command either prevents the movement or does not perform it correctly. As a result, the user must manually search through the assembly tree to identify the level for which Continue has not been selected.To prevent this issue, we request an option such as “Continue for All Affected Components” within the Drag Components command. This option should apply Continue to all affected subassemblies and components in a single action.

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.

 the image is related. whenever i try to open the file it shows this blank screen. I’m new to creo student edition and don’t know much. I was previously an onshape user. i had made backups and made sure to save it a couple of times before closing. The random save i did while sketching is visible for some reason but none of my extrusions are visible.i scanned all my pc’s recent files to see if i had accidently saved it somewhere else too but its to no luck. The sketch from the above mentioned case is not fully visible too. 

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

Hello I have a reference pattern created from geometry present in another part in assembly. Referenced pattern does not get updated automatically, when I update my parent/main feature. What could be the main reason refernce pattern does not get updated automatically when refernce with external geometry. I have also checked the update control is set to automatically . TIA

I have a user how is simply trying to save a shrinkwrap on a simple part, but when he goes to Save As, before he gets anywhere his Creo 10 is freezing and generates an error as follows:The defined Environment file for the model scene is missing and will be replaced with the Creo Default Environment file. You can update the scene by selecting the desired Environment file from the Scene Editor under the View Tab.I can’t seem to find any info on this. He’s not in render mode or anything like that. There is nothing special about what he is doing. Seems like it is now all files, so its “environment related, not a specific part/assy issue.  I tried with the part on my computer and it works as expected.

My Company recently ungraded to Cero 12 from 8. There are a few changes made to the whole cabling side of Cero. I have been able to work through most of it but now trying to add the terminal information has been tricky/I can’t get it to work.In the past we have added in the terminal table to get all that information and eventually use it when making the drawing in the to-from table. We also have another smaller table with some of the same info for each connector.To make the BOM accurate we make blank parts with the part numbers of terminals, locks, and seals and place them in the assembly so the table is accurate.So far I’ve tried making new terminals which just throws the “name already exists” error and when I try and import them from the old trm files the same thing happens. I would assume this is because there are part files that already exist and not from the trm files.  If anyone has a solution or work around that would be much appreciated.

Hello Creo API team,We are building a Creo Plugin . We already have tessellation data in memory:Vertex coordinates (x, y, z) Triangle connectivity (facet index list) Optional normalsCan we create faceted/mesh geometry in a Creo part from this data programmatically (no UI)?Specifically: Is there a public ProToolkit API to create mesh geometry directly from in-memory vertex + triangle buffers (similar to passing a vertex buffer and index buffer)?If not, what is the recommended approach Environment: Creo 11.x, ProToolkit C++, Windows x64.Thank you.

Hello,   I am looking for a fast way to exclude items inside a pattern or group.  This would be applicable for simplified reps or shrinkwraps.  When you create one of these two, Creo opens a separate window that allows you to pick items to exclude.  However, if there is a pattern or group you have to expand all the way down to the part level and shift+select all the parts to exclude them.  This is the case even in the model tree when the rep is active.  Is there an easier way to exclude all parts under an assembly or group?   Thanks all, MattThis thread is inactive and closed by the PTC Community Management Team.

I have two calculation sheets: One is L55-529.7255, and the second one is L55-538.6610. I need to import the functions E529 and U1 into the L-55-538.6610.And the values of E529 and U1 are added to E538 and U2. All the functions are defined with matrix notation. But when I apply the command “Include” the function E529 is ok in the sum, but U1, it says “this variable is undefined. Check that the label is set correctly”. But if you escrow down to the last sheet in the file L55-529.7255, you can see that there are no errors and that I am able to sum E529+U1.I tried in the opposite way, importing L-55-538.6610, using “Include” into L55-529.7255 and I have the exact same error. But I cannot find what the problem is with the U1 function when this is imported in L-55-538.6610 and U2 when this is imported into L55-529.7255. I am including the two files. The functions U1 and U2 are defined in the before last page, and all the sums are completed in the last page. The majority of the calculations

I am still using the old Mathcad 11.2, despite the difficulties with the new OSes. I asked to ChatGPT for help, but I did not get any solution. I wrote (see picture) two equations, and I asked to solve for variables p and w symbolically. Afterwards - and only afterwards - however I would like to capture the symbolic solution (in this case of variable w) and turn some symbols into numeric values and make relations with just few variables like w vs. r, so to obtain a function like w(r):= etc., that  I can plot it.As can be seen from the screenshot, however, MC11.2 appears unable to assign some variables the specified values. ChatGPT suggested defining a new variable and then “optimizing” it, which I tried using wR(r):= ..., but that approach did not work either.Of course, one could simply copy and paste the solution returned by find; however, I am curious to know whether there is a way to achieve the same result avoiding such a manual intervention.Thanks in advance for any suggestions or

I am a fun of Mathcad (the classic version in my case), but far from being an expert. So sometimes I come here, but recently I often use AI chats to query for basic help. I found that ChatGPT and Claude (free plans) are probably the most responsive models in my case. But they tend to not follow always my prompts that I am still using MC11.2 old version. But there are many other AI models around.So I would be curious to know what kind of AI models new and experienced users here prefer - if they use them at all.Thanks.

i Have PTC MATHCAD PRIME need a function to generate a cumulative sum sequence where Ui=0 and Ui-1 =0, iteratively calculating Ui+1 up to a 4094 rows , 1column vector. 

I am using Creo Parametric Release 7.0 and Datecode7.0.9.0 This is not my exact problem but I think might help explain my problem. Imagine I have an assembly of a mechanical based clock. It is an assembly of many assemblies and parts within. Many layers deep. Various parts of the mechanism move and I would like to define several assembly positions. For example....I would like to load the clock assembly showing the position of all the external and internal parts in 12:00 position.....3pm position and say 18:15 position. The BOM stays the same. Can you provide some clues on how I might achieve this? For example, Can I use just simplified reps? Its the many layers deep which I'm struggling with.
