I have a problem with the eigenvals() function. USALLY the results are sorted from largest to smallest, but occasionally they will be out of order. I have found the following simple matrix that demonstrates this:[A] = 1.0053 1.0053 1.0053 1.0053 2.0001 2.0001 1.0053 2.0001 3.4365 eigenvals(A) = {5.301 0.337 0.803}This can be a tremendous problem if, for example, I have a 100x100 matrix and I only need the first 3 eigenvalues and their associated eigenvectors.See attached mathcad sheet with demo and illustration of what I go through to sort the values and vectors properly. Surely there must be a better way!

I have a sinusoidal mechanism I am trying to simulate.  I can get the kinematics to work fine by using two mechanism constraints: the first being a cylinder connection which controls the axis and angle of my assembly.  Then I projected a circular sketch onto the sinusoidal surface and used a slot constraint where a point follows the projected curve.  A spring keeps these two surfaces in contact.  In the video I can have the structure swing back and force indefinitely due to the force of the spring.  There is no friction in the system yet.  I would like to have the two surfaces generate friction to eventually damp the system to 0.  Is this possible?  I haven't had any luck with either cam or 3D contacts.  (view in My Videos)

I am using Creo Parametric - Release 6.0 (connected) 6.0 6.0.4.0Y-201-31-0209_CL_PIPING.ASM is locked in the workspace,but it will show "modified in session" in the server status column,please see the attached screenshot.would you please check if there is a problem with status?

Hi Is there a way to lock joints temporarily when dragging components. 

Hi, I am new to Creo Illustrate and I'm trying to wrap my head around using it. I'm using Creo 7.0. When it comes to standards - they contain all the needed styles, symbols, properties. I know how to create a standard, export or add one but I can't seem to be able to find how to edit a standard. It seems a natural thing to be able to edit such things - specifically I need to add some symbols "on the fly" when I come across a need for one. I found out I can download a zip file with text based setting for standards but it's painfully time consuming to edit that every time I need to do it and I don't even know as of now if I'll be able to add proper symbols or callout using this workflow. Could you please let me know if there's a way to edit symbol library or callout library a "normal way"? Kind regards, Tom

Is there any way you can make a block or symbol on a drw and then have the user be able to click that block and have the users go to a Windchill object? We have these P&IDs with a bunch of symbols on them that link to objects in Windchill.  We want the user to be able to click on P&ID and go to the object page.  Anyone have any solution suggestions? Thanks, Kenny. 

Hello, I would like to solve an equation containing vectors (the result is also a vector) using programming. I tried using the solve block as indicated in the attached file, but I don't obtain the expected results (see Case 2). The expected result should be equal to the "y" vector from Case 1 highlighted in grey. Am I using the Solve block incorrectly? Is it possible to create a program for this situation (proffered solution).I am using Mathcad Prime 8. Thank you,Otilia

I am using Creo Parametric Release 6.0 and Datecode6.0.6.01. CCX, which creates the necessary cross section while running CCX and viewing the analysis results, is terminated. Is it possible to do cross-section work while looking at the result in a state where it cannot be finished?2. How to adjust the line drawing and thickness displayed when viewing CCX progress?-----------------------------Translated this post from Korean to English at 1:37pm IST(done by vnamboodheri) Subject was: CCX를 실행하고 분석 결과를 보면서 필요한 단면생성하는 CCX가 종료됨Body was - 1.

I have a part model that has part level parameters that seemingly impossible to delete: The issue seems to be because they were once used in a sketch feature to drive a text label I've deleted all the features in the part and yet these parameters persist.   Did anyone encounter this kind of a situation and what was your work-around?

When i select the infinite horizontal construction line from the ribbon, the construction line automatically snaps on the part edges as you can see in the 1st pic bellow. But when i add a shortcut for the construction lines, and select the same command, the line doesn't snaps anymore (2nd pic bellow). I don't know if someone can help me, I'm new at this software .     Thanks.  

Hello All.   This question explicitly is addressing Mathcad PRIME (Current Version 8).  Not Mathcad 15. Is there a workaround on how to "easily" employ the Del Operators such as gradient, curl, and divergence in Mathcad Prime.  We can do it "long-hand," but not like what we had with Mathcad 15, so the Mathcad Prime presentation of the equation is more intuitive to students and closer to what we write on the chalkboard.  I can roll with the use of the Einsteinian Notation or Vector/Del or even just plain grad(), curl(), Div() notation. Cheers and Thanks.Bill CapehartSD Mines

Hi,I would like to know if there is any approach generate this geometry just redefining a feature curve end getting this geometry (see OK.png) The idea is adjusting this sketch curve the solid geometry to be update, but I was not able to achieve it just changing the feature curve. I'm able to generate this geometry (see NOT OK.png), but I don't need the round ends. I was thinking if there is any flexible modeling feature or any approach to remove the round ends. Thx,CC 

I am attempting to add a marker on a pre-defined cable assembly. The part is in assembly mode, and I am unable to open the cable assembly separately. I see online that I am supposed to use a marker.  To Apply Marker to a Cable1.Click Cosmetics > Marker.The Marker tab opens.2.Select a segment of the marker.3.To accept the default length, diameter and thickness click the check mark. 4.The marker is created with the default values and the tab is closed automatically. I cannot find the 'cosmetics' icon to create the marker while in assembly mode. Can anyone help direct me? 

As per the original post.    Can someone help me to convert this file in mathcad 2020(mcdx)?

Hello all, I have been working on this project to evaluate Weight as a function of Pressure, however, I haven't made much progress as I continuously get the error [Replace complex values and NaNs with real numbers]. I've been using Mathcad as a means to avoid coding but at this rate I may need to. Best, Cruz J.

Hi, I am a secondary teacher I am using Creo parametric 7.02 and there seems to be an issue in the render studio. When editing a material I alter it in terms of rotation or scale and then when it’s rendered it changes and isn’t what I have set up. Has a anyone else had that issue or can you give me any advice.

Hello, ProGtoldataPlacementGet is deprecated in Creo 9 and it says that it was superseded by ProGtolAttachGet. One of the fields that ProGtoldataPlacementGet would retrieve is the ProGtolPlacementType which is the field that I need. Is there another way to get the ProGtolPlacementType, or do I have to convert the switch cases I have over to the ProGtolAttachType instead? Thanks,Mark

I have a very annoying problem that I have just recently discovered in my FEA models. The issue appears to be present in an older version of Creo 2.0 and an a newer version of Creo 7.0 and it has taken me countless hours of frustration and failed meshing to figure it out. For some reason I can take a model where all my pinned joints are perfectly aligned (this can be verified by checking with the measure tool) and import them into Simulate only to have them shift ever so slightly (like 0.00003mm misaligned). The problem is that the shift is just enough to prevent AutoGEM from meshing the parts and no amount of reconstraining or regenerating the parts will fix the misalignment. Generally the only way to fix the problem is to close out everything and reopen the models and try meshing again. This is incredibly frustrating and wastes a significant amount of time. Anyone know how to fix this?

Hello guys, I am new to this forum and this is my first post. I would appreciate input from others regarding my problem. Maybe I did a stupid mistake so please excuse that. In the picture you can see that I assigned all the Units regarding my Problem that I want to solve for, but nevertheless, mathcad tells me they are not compatible.   

Hi all Sometimes, my users doesn't defined clealy their kinematic links.They forget to put a regen value and active it.... I activate the MECH_COMPONENTS and set it to W in interact, but when i test it, MC only show me the parts with kinematic links even they are completetly defined. Can i set ModelCheck to control the correct definition? Regards Dom

From what I can tell, if I want to change the model representation (using a simplified rep) that is used in a view and a repeat region BOM, one must change them both separately. Either one is changed/switched, the dwg deletes all the attachments and balloons that have been organized to each component, and this is regardless of which one is done first. Does anyone know how to swap both the view and the Repeat Region Representations so that the balloons and attachments for the remaining components (the ones not excluded by the simp. rep.) are not lost?

As per this thread - same issue   Good afternoon, Sorry to reopen this old post but it is related. I'm trying to open a drw via Jlink, it works correctly BUT it don't open the window with the various sheets this: Instead of this:   Anybody has some hints?   Thanks in advance.

I need to support two licence files (different companies) on the same server.  Its easy enough to set the ports to different numbers, but ptc_d insists on creating lockptc_d in /var/tmp.  Setting TMPDIR doesn't seem to help.   Does anyone know a way (or an environment variable) to force it to create its lockfile elsewhere?   The issue is that when starting the second server, it can't open the lockfile and then dies. Thanks, 

I can hardly believe that I did not ran into this bug in the past. Or maybe I am blind and doing something wrong? Why is the horizontal base line if the second triangle not drawn in the combined plot? IMHO it should work (and I hesitate to say so, but it actually works OK in Prime). Has anybody already experienced that bug? Has anybody an explanation (other than "buggy programmed" 🙂 Has anybody an idea for a workaround? I thought that using complex numbers may be a way to get what I want, but, alas, to no avail! BTW, the problem goes away if the tringles don't share the common point (1;1). More precise: The problem seems to be that the last point of the first triangle is the very same as the first point of the second one. Sure in this simple example the order of the points could be changed to circumvent the problem, but in an automatically created list of a larger number of different shapes this seems not to be an inviting option. Any ideas are welcome. Mathcad 15 file attached &nb

I am implementing a material nonlinear simulation for an aluminum tube. I fixed an end of the tube and used displacement constraint to another end.The ultimate stress of the material is 440MPa. What simulation or how to set up parameter to measure the moving constraint when the ultimate stress reaches exactly 440Mpa?
