Hello,   is it possible to measure the lever force over time in Mechnism dynamics?I have a simple lever mounted in the middle. On one side it is moved with a hydraulic cylinder.I know the displacement and the force in the cylinder. I would like to define these parameters. The vertical force that acts on the other side of the lever, I would like to show over the cylinder length or the time. Is this possible? Unfortunately I did not find anything in the help.   GreetingsMorian

When exporting a Creo 8 drawing to DXF format, the DXF preview shows random text superimposed over dimension text.  This extra text carries over to the DXF file.  Attached is a screenshot of the DXF file in AutoCAD 2022.  {ftxt is not supposed to be there.  Is this a bug with Creo 8 or is there a way to fix this? Dimension Text:.720 {1:@+.728@#}{2:@-.712@#}{3:@- @#}[18.3 {5:@+18.5@#}{6:@-18.1@#}{7:@- @#}]MDF FINISHED@O THICKNESSSPECIFICATION  

Configuring Creo 8.0.8.0 along with IPEM 13.0.3. I'm using a mapped network drive (eg Y:\start_models) to store our start files for all users to access. The line is set properly in the config.pro file & when I launch IPEM/Creo the logs say it read the config.pro, but when I start a new file I'm still getting the default OOTB start files in the File New dialog.Anyone else experienced that?Thanks      

I am using Creo Parametric Release 9.0 and Datecode9.0.3.0When I merge two quilts together it is difficult to distinguish the surfaces and which parts will be cut and which parts will be left.There used to be a config option in proengineer that helped with the preview of the merged surfaces in that it showed exactly what was going to be cut away and what was left.Does any body know how to do this in version 9.0?

Hi All, We added some leader notes in a drawing that we were working on. When we open the drawing in the CREO Parametric instance we worked on, they are oriented to the right.If we open it on another users CREO Parametric instance, they are oriented to the left. If there a CREO Parametric Setting that affects this or can cause this behaviour?    

I am using Creo Parametric Release 9.0 and Datecode9.0.4.0Hello, I am having issues creating a bundle of wires. I have created the spools, designated the connectors, and successfully connected the connectors using wires, and I am able to create a bundle around a single wire. However, when I attempt to add wires to the bundle, I get an error message stating that it cannot be added to the bundle. I have reviewed all of the provided documentation on bundles, and the potential cause of this issue is not outlined. Can someone please help me identify any steps that I am missing in this process?Here are the errors that I facedCable can not be added to bundle.

I am using Creo Parametric Release 9.0 and Datecode9.0.3.0I am trying to unpattern a patterned group and make all the features independent of each other but I can only find "make independent under the model, operations, ATB menu which doesn't seem to work. Can you please help.I have had a look at the rules for patterning groups in the fo;;owing website but it doesn't seem to help much.https://support.ptc.com/help/creo/creo_pma/r9.0/usascii/index.html#page/part_modeling/part_modeling/Rules_for_Patterning_Groups.htmlAlso had a look at CS131620 - see website below but it doesn't seem to apply to release 9.0https://www.ptc.com/en/support/article/cs131620?language=en&posno=1&q=unpattern%20and%20make%20indep&source=search&_gl=1*lb9m8o*_ga*MTk4NjQyMTY4OC4xNjkxNjk2NDI5*_ga_CBN5QVB9VJ*MTY5NzQ0Mjk0MS4xNC4xLjE2OTc0NDI5NTkuMC4wLjA.*_ga_1QBT6P6HR1*MTY5NzQ0Mjc4NC4zMi4xLjE2OTc0NDI5NTkuNDIuMC4w

Hi,I would like to add a PDF which comprises several combined pages to a PVZ file in order to be able to view them in Creo View not as separate files but as a set of pages to utilize the "page" utility and make viewing instructions more user friendly. I can think of one way, which requires 2 steps:1. Include the pdf in the PVZ zip file2. Edit the structure .pvs fileHowever, the pvs file, when open in notepad, contains pdf file names and some uncommon ASCII characters, which make barely any sense. Not only that, but when I just open the file and save it without any actual edits, I get an error when trying to open the PVZ file in Creo View. Is there any other way or any specific editor for PVS files I could use to achieve my goal? EDIT:I've got this weird thing where I find a solution to my problems as soon as I post a question... Solution - just open the pvz file in Creo View -> File -> Add Viewables to Session -> Save all

Let's say I brought a model into a manufacturing assembly. And, since I wasn't paying proper attention, it was just brought in as a "regular" assembled part. Now, realizing the error of my ways, I want to reclassify that part not as just a dumb component, but as a reference model. This would seem to be simple enough, There's an actual "Classify" button. But, every time I've ever tried that button, the message is always "This component cannot be reclassified". So, a simple question, what use is the Classify functionality? It never does anything for me. Is there some esoteric situation where it is actually useful? I can't just redo assembly of the model, because I've got a lot of toolpaths that already use it.    

Hi,is possible launch creo parametric at a specific location on the screen?I use windows_scale 0.5 and the window moves to the top left.I would like to open more at the top right, down left & down right. Thanks 

Hello all, we´re trying to find a smooth way to share and update an illustrate standard maintained via the Administration tool to several users.Is there a nice (and possibly native) way how to do?I can also imagine something within sharing the standard via Windchill Question is related to Illustrate 9 &10 Similar question was already raised here , but not about the sharing / updating of an standard 

Good morning community. I am trying to interpolate with certain conditions with repetitive data, a way to program, please if someone give me an idea. Mathcad Prime 6.0.0.0 is being used.

Hi there, I use a Logitech Master MX Master 2S, and currently have no use or shortcut for the side scroll when using Creo Parametric (If anyone does have any please let me know!). Does anyone know how, or if it's even possible to add a shortcut that allows panning or rotation when the side scroll is activated? Thanks, Robbie     

Hello,for many years I'm using Creo Elements Direct Modeling Express 6.0. Some weeksago I installed Creo Elements Direct Modeling Express 8.0 on my Windows 7 pro.Once Creo Elements 8.0 is runnung with a opened pk2-file and I want to add anotherpk2-file from the Microsoft Explorer by clicking on it, then Creo Elements 8.0 thepk2-file opens in a new instance and a second prozess is runnig.Is there any setting for Creo Elements Direct Modeling Express 8.0 in which thisbehaviour can be changed?

Hello,I am using Creo Parametric 4.0, I wanted to create a simple cable drawing. I started with creating a 3D routing of the cable set that consist 2 connectors connected with 2 cables. Once I flatten the cable set one of the cables is shorter due to it's routing. I'd like to ask if there is a possibility to connect it to the connector for a drawing purposes. Maybe there is a way to fix the length so the cables uld be equal.Thanks for all suggestions.    

dear expert how can use tilting work plane g68.2 p0 in creo 5 axis? regards Asif  

Hoping someone could point me into some direction with it have one user on the floor, creo view on ipad, sent the pvz file (same that others are using) and it just opens creo view but doesnt show. Tried cloud host, local file, usb transfer, you click the pvz, open with creo view, and it just loads the default screen showing only the default preloaded gearbox part and does nothing.  

Hi guys,when I open the help center in modelling Express, the program opens in automatic on "Internet Explorer" like the picture below.This browser is not my main preference. There is a possible to change it.Thanks in advanced 

I'm using creo7 parametric and I'm trying to make the material in the title block be a drawing flag symbol using &sym(FLAG-MUTI-LEVEL). Normally when I type this in a text box, it will give me the symbol dialog to select the options I want such as what number I want in the flag and the size of the flag. When I put &sym(FLAG-MUTI-LEVEL) in the &MATERIAL parameter, it just shows it as text instead of the flag. I don't want to get rid of the &MATERIAL parameter, I want to have it equal to &sym(FLAG-MUTI-LEVEL). Thank you!   

How can I populate table using dimensions from a pattern table? All Csys are in a pattern table. I am using Creo 7.0.5.0   __PRESENT __PRESENT __PRESENT  

Our company is planning to upgrade out CAD software to CREO 9.0. However, the CAD support matrix for Ansys 2021 R2 does not go beyond CREO 7.0. Will these versions cooperate properly? (Upgrading Ansys is a long and difficult process because of internal requirements, avoiding at this time is beneficial if possible)  

Hi everyone, I hope you are fine.I need to change the color of the result word, if it was safe to be green and red in case of unsafe.      

I need to plot the intersection and return it as a value.I have lines to show minimum and ideal operating temperatures but I would like to find the cut-off temps for each of the proposed AC-DCs. I have a graph that has the output derating so the line isn't a simple ab2+c so I have to use a function. I would like to know the maximum operating temperature of the multiple power supplies. Based on a Wdc1(Tempamb).  I tried using solve but this doesn't appear to work on functions. as the derating is not constant across the full operation range. see the example of the function I am using below. What is the best operation to achieve this? I have attached the worksheet for referenceI'm using MathCAD Prime 8  

Hello,I use "set representative"  function to a module variant in a "configurate module";And Creo created a "Representative Module Variant"  representation in the "configurate module" file;But my configurate product is nothing changed, Is there any function can let onfigurate product use the "Representative Module Variant" representation automatically ?Thank you！
