CAD

I have been performing drop testing with a product.  Collected data shows displacement during the freefall and deceleration to a stop.  I've tried several methods of data smoothing and curve fitting.  The best I have achieved gives incorrect initial velocity and acceleration.  In the image below, after smoothing (blue line), it shows an initial velocity rather an acceleration from zero.  Any ideas on how to accomplish my goal would be appreciated.  See the attached Mathcad Prime 9 document. Thanks, Bob 

Hello, everyone. More than a question, this is an open topic: Does somebody know a reason why the piping application has not been updated in all these years since Pro/E became Creo? There has not been any change in the way to do piping. I know, some people use to do by swipes and extrudes, others use piping app, and others do spec. driven. But in general, we have had enhancements for manufacturing, electrification, sheet metal, ... And what about piping? Anything? Competitors are WAY FASTER AND SIMPLIER to design routed systems than Creo (for piping/tubing). Will this post be seen by PTC people someday? Let's discuss in the comments.

Hello Community Members, I would appreciate your help in fixing the solution to a second order differential equation. I am attaching the spreadsheet I created in Mathcad 10.Thanks in advance for a timely feedback!Best regards, Peter

Hello,  I on Creo Parametric 8.0.9.0 Is there a maximum amount of columns in a hole table of datum points? I would like to add over 23 columns to the hole table of datum points.I added a bunch of parameters to the datum point feature. These parameters should show up in a table on the drawing. A hole table of datum points is used. And an export of this hole table is needed as input for another application. While doing this, only 23 parameters, including the standard the standard 'Feature Name', 'X', 'Y', 'Z'  can be included. When adding more parameters, to show up as column, Creo crashes. A fatal error is encountered. So I was wondering if there is a max to the number of parameters to be added?  Thanks for any reply,  Johnny G

Hello community members, This is my first post on this forum. So i hope this place is somewhat active.I have an issue where my assembly is loaded many meters away from the origin.I can fix my issue by moving the parts within the assembly to the origin.But then a more annoying problem arrises.Now my origin is correct when loading in the model. But when I go to create a view in my 2D drafting environment, my origin is now still at the original location.And my view becomes hard to allign to other views. So my question is: When and how is the model origin decided? And can I change this within an existing model that is saved in a database?

I have a program that I have written for a fixed time step and then advanced it for two, but obviously I want to do this for many. I thought I could just do this with a for loop but I have various matrix operations in the program and cannot get the indexing right. Do I need to convert everything to indicies? There must be a simpler, more elegant and efficient way. The program is highlighted and annotated at the bottom of the worksheet. There are some auxiliary programs at the top. I am using MathCad 14. (BTW I do have a reason for setting the ORIGIN to -N, but I do not think this is relevant). Thanks in advance for any help.

I am using Creo Parametric Release 4.0 and DatecodeM150We currently face a challenge in opening “.lay files”.Is that part missing in “PROE_DesignEssG”Here are the errors that I faced"this funcion requieres one of the following:NOTEBOOK

Hello I am want to use Mathcad to build  a mathematical model from several  physical formulas and later on substitute either numerical values either lower formulas. The 1st difficulty I meet  is that I would expect hereafter to get numericla result in the variable JSyst. Currently the error is "undefined variable". Another strange thing is the numerical resuls from the Solve command is not combining the unit. Is there a common explanation ? PTC Mathcad prime 9.0.0.0

Hi everyone,I want to do a linear interpolation for k in MATHCAD from this table taken from EC2.As you see, if the division c1/c2 is <= 0.5 the value must be 0.45 and if the division is greater than 3 k is equal to 0.8.How can i solve this. Nota: I'm new to MATHCAD.

Hi,unfortunately only v7 and above is still available under this link?Unfortunately my old hard disk with Mathcad v4 is broken and I still have a permanent license. How can I get a Mathcad 4.0 download? Regards  

I am new to creo and the creo family of products. When I create a cdi from the pvz and attempt to save the illustration, create a mp4, etc., I get the manifest is missing error. I am working on a pvz on my desktop outside of plm to experiment with animations as my company is working towards adding animations to for our service techs. I found an older topic about deleting the cache to fix this error by going to %APPDATA%\pts\illustrate, but I cannot find this location in CREO 10. It has become frustrating as I put work into these animations and I basically am losing all my work. Thanks in advance.

1. Received an email for the Mathcad Express download2. Clicked on button, the file pim_installmgr_mathcad.exe was downloaded.3. Run the a.m. file. Extracting... window appeared, when completed it closed and no installation happened I have a 64-bit operating system with windows 10.  Tried to run as administrator as well.Thank you.

i want to relate symbol with view by using C# and VB api. any one know solution give me a help.

I asked questions in the collaboratory several years ago, and as far as I can tell, many of those issues were never resolved.  How may I get my old Q&A so I can go through them and compare the issues to the newer versions of MathCAD? 

CREO 10 CAN YOU COMPLETE A SWEPT BLEND (OR ANOTHER WAY IF THIS IS NOT THE CORRECT FEATURE) FROM A PLANER SKETCH TO A CURVED SKETCH, OR PROJECTED SKETCH ON A CURVED SURFACE? HIGHLIGHTED IS THE PROJECTED SKETCH ON THE LARGE BODY, THE CURSER (SMALL RED LINE) IS THE OUTSIDE SKETCH OF THE DUCT.  FOR THE DUCT, I MADE THE BODY WITH A SWEPT BLEND.  HOWEVER, I NEED TO ADD AN OUTSIDE THICKNESS LAYER WHICH WILL STOP AND CONFORM TO THE OUTTER SURFACE PROFILE OF THE LARGE BODY.  SO BASICALLY, I NEED TO CREATE A LOCATION STOP/SUPPORT FOR THE DUCT (THIS IS REASON I NEED TO ADD EXTERIOR THICKNESS TO THE DUCT), THIS WILL ALLOW ME TO PRINT THIS SEPERATE (IN A DIFFERENT COLOR) AND ASSEMBLE IT TO THE LARGE BODY.  IT IS CRUCIAL FOR ITS LOCATION AFTER ASSEMBLY. I CANNOT PERFORM ANOTHER SWEPT BLEND FOR THE EXTERIOR TO CREATE THE THICKNESS BECAUSE THE SWEEP WILL NOT STOP AT THE CURVED SURFACE.  WHAT ELSE CAN I TRY?? ANY HELP IS APPRECIATED.

Well it looks like the Collaboratory has died http://collab.mathsoft.com/~Mathcad2000. Not even a redirect notice.It was good while it lasted.Philip

The Problem Has this happened to you?   You are involved in the development of a new process.  At this early stage in the development, the catalyst developer has some indication of success, but there has been no kinetic study conducted.  Thus, the reaction network is only partly known, if that.  Because the development team is following the Scale Down development method (see earlier blog article), you have been assigned the task of creating conceptual process alternatives using a commercial process simulation program.  This early process study may reveal information that may help the catalyst developer "tweak" the catalyst toward the more economical set of selectivities.  Also, getting an early start on the entire process design will help prepare for more focused optimization later in the development.   For the reactor model in the process simulation, you will be using the stoichiometric reactor option.  You have been given the list of reactants

Hello, I'm trying to upgrade to Creo 10. I received my license text files through email. I went to the software download page and got the latest version of Creo 10 (Version: 10-0-4-0) and downloaded the .zip file. The problem I'm having is that the setup.exe file does not seem to work. When I double click or right click>run as administrator nothing ever happens and no installation window ever opens. However, when I go into Windows Task Manager I see a process called "PTC Installation Assistant" which is running. If I don't end that process I get an error when trying to re-run the setup.exe file which states "Please exit the already running installer or uninstaller first." I was able to successfully run the "install_license_server.exe" and it recognized the license lm___.txt file and installed the license server successfully. That does not seem to help getting the setup.exe file to work. I'm running Windows 10 Enterprise. I've seen a few possible solutions on this foru

For reasons of convenience I would like to have a closed surface where one of the edges is open in Creo Parametric. A simple example could be a surface of revolution that is swept 360 degrees but has a open edge where the surfaces meet. Below is a artificially created image, where the sweep angle is close to but not exactly 360 degrees. Revolved surface with open edge (but not quite closed) So i am wondering is there: A way to split a self enclosed surface at one and only one edge?A way to merge only said edge and not all edges?Convert inner edge to outer edge?This would be handy at times.

Hi,I am attempting to include my custom component as a connector in the AFX library.In the script tab file, I'm adding connector references for assembly. When I try to assemble that connector and the connector references are in the hidden state, afx displays an error.For example, if I refer to a plane from a connector for assembly and the plane is in the Hide state in the connector component, afx will fail to assemble it.We are using Creo 8 and Creo 10.We use MBD for parts and ensure that all datums are hidden for the Model_only tab. Anyone know how to use connector references, even if they are hidden ? Your help is  appriciated.

Hi,to automate the drawin of numerous part, hasanyone made a Creo toolkit application that can generate max dimensions for a given 3D model?3 parameters must be generated in the 3D modelMAX_LENGTH_XMAX_WIDTH _YMAX_ HEIGTH_Zand  coordinate of max points alwais  referred by coordinate system (see example measure transform) ?Thanks for your time, Luca.

I was using Creo (v10) under a school given license for about 4 months. Since this license only worked at campus and I needed more time to work, I decided to add the online student license that my friends recommended to me.  At first, it was not working and continued to operate under the school's license and did not work away from campus. Then I went on my desktop to Creo open file location> Reconfigure. Here I went to the licensing page where I only found the student license. I accepted and went through with everything hoping that Creo would now work under the student license like how I wanted it to.Instead, now every time I open Creo it says that I must register the Quality Agent for Creo to keep running and when I allow it to register it it says that Creo is shutting down under code 0x00000013. It might be helpful to note that when I first installed the student license under my laptop and it did not work I installed it on my PC and did a project on it meanwhile.

Hello everyone, I require your expert assistance in setting up a 2D parametric plot to represent the geometry of a miter bend.The attached Prime 7 worksheet contains the formulas driving the plot. Although I utilized AutoCAD to sketch the miter elbow from the results from the worksheet, I need to recreate it in Mathcad through a 2D plot. The ultimate aim is to generate a DXF of the 3D object for import into the 3D design software but my first priority now is to achieve the 2D plot in MathCAD prime.       

Good evening, all.I am in the process of migrating some old MATHCAD 15 worksheet to MATHCAD PRIME 10 ones.I came across this vector field plot that MATHCAD 15 was able to plot and I found that the latest PRIME versions do not have such a plot type.I am pretty confident that someone in the community made some script to replicate such a function.I already saw some attempts made in other threads. However, they work for 2D vector plots.Any chance that someone did for the 3D vector plots as well?I am showing below the type of plot I am looking for.Thanks in advance for your time and support.Regards,Gianfranco
