CAD

to all, A question regarding the Cholesky LDL decomposition. given a matrix A one can have A=LDL* where L* is the transpose of L using the mathcad 15 cholesky(A), how does one code mathcad to get D? L = cholesky(A)   Thanks in advance Josh

I want to place a symbol positioned on the upper line of my drawing title block, which is in a frame (A4,A3 ...)But it seems Impossible to catch the upper line of this title block to snap with the position origin-point of the symbol. Is there any solution to position this symbol exactly on my title blocks?  

New features for consideration:          

Hey guys, I really need your help on this.I'm using CREO by a whole server created by H.O. so excuse me for having not much information.I'm trying to use the AFX system so I went looking for it in the community.1. I tried the reconfigure.exe but It seems H.O. somehow prevented other people from changing the configuration. So I couldn't find out if  the license actually exists.2. I went through the installation directory and found out in Common_Files there IS an AFX folder.     I'm curious even if we don't have the license, can the folder be created?3. I tried going into the option and checked that afx_enabled's value is yes. But when I go to the ribbon menu actually there's nothing showing. Is it the H.O. that's not giving the license for AFX, or are there any different solutions that I don't know?  

Hello,   How would you compare Mathcad with following software?   What would be the advantages of using Mathcad (Prime - because it was chosen to continue with MC Prime further)  compared to the following software: Standard Maple, Maple Flow, Wolfram Mathematica or Matlab? What would be the disadvantages of using Mathcad (Prime) compared to the following software: Standard Maple, Maple Flow, Wolfram Mathematica and Matlab? Why do you prefer Mathcad (Prime) instead of the other software: Standard Maple, Maple Flow, Wolfram Mathematica or Matlab? Or do you use the other software listed above besides Mathcad (Prime)? Why? Is it really better to use Mathcad (Prime) compared to the other software above, at least from the point of view of say the following fields: Engineering/Electrical Engineering, Control Systems, Signal Processing, Calculus, Matrices, Algorithm (convergence, accuracy, precision), working with units, programming? Is it worth messing aro

Hi, can someone help me by converting these old version of file (05 files) so I can open it in Mathcad Prime?  My option to convert the file is also grayed out. thanks!!  

I have been having an issue with regeneration of only certain assemblies.For some reason whenever I activate a window of a large assembly that my coworker created in a folder it has long regeneration times (it doesn't do the same for him). But when I open an even larger assembly created in another folder, that has similar components, the regeneration time is instant. Does anyone know what could possibly be causing this?   

OK, limitations 1. Why do I have to carry out a fatigue analysis on a whole assy?- There is a file containing stress results by part/volume region- One could carry out a fatigue calulation with the stress results from a single node by hand but it is lazier to use software (and less human error probably)- I suppose I could fiddle with the results files and make my own up. The software would be unable to tell the difference bewteen one I create and a 'real' one. 2. Why can't I select a contact analysis?- There is a file containing stress results by loadstep.- Ok, ignore contact stresses but why not be able to go the the final loadstep automatically- Yes I know it's non-linear, But sometimes we need to be pragmatic engineers. Again, I suppose I could fiddle with the results files and make my own up. 3. What 'location', 'label(s)' would you use for this? What message tags would you create?   

Hello, How would one set limits for the variable in the solve command.  In the example below, I know that k has to be between certain values.Thanks,  

I am using Creo Parametric Release 3.0 and DatecodeM090A couple of our engineers are having problems with opening and modifying models and drawings without Creo crashing. It happens with everything they try to open. Another engineer and I have tried opening one of the same models & drawings and it works fine for us. One of the engineers has had crashing issues off & on for some time. I have a traceback.log file and the trail.txt file she sent me from the last crash.Here are the errors that I faced-------------------------------------------------The trace creation timestamp is: Wed Feb 08 15:45:26 23The executable build timestamp is: Thu Mar 24 06:14:53 16The datecode is: 2016050The pro machine type is: x86e_win64The process ID is: 20292The traceback type is : CRASHThe logger exit status is: 00003The release is: 3.0The external datecode is: M090The product title is: Creo Parametric-------------------------------------------------Exception EXCEPTION_ACCESS_VIOLATION has occurred

Hi,        I would like to know how a radial arc length dimension can be shown in a drawing view in creo elements also would like to know how circles or any isolated lines can be made hidden or removed from a main body surface in a drawing.   Thank you.            

Did you find a solution to this?I'm experiencing the exact same situation .    RE: post

I use this functionality often, but I can't find how to get to it.  OK, that sounds funny, but I access it with a very old mapkey that enacts the old cascading menus.  How do you access this using Creo 9 menus?  As a secondary question, how do you access the cascading menus without an old mapkey?  

Does the mathcad subscription license (Prime8.0) support version 15? I can run Prime 8.0, but when I run version 15, I get a license error (-2, 15, 8, etc).   

Hallo you all, since a while i cant access Mathcad full version while beeing connected via public wifi. With my home Wifi it works fine.disconnecting VPN doesnt make a difference. Do you have any ideas whats the problem. Since working remote its kinda annoying. Thanks!!

I am using Creo Parametric Release 6.0 and Datecode6.0.3.0go to add assembly to workspace and receive "Server error: Cannot retrieve family table neutral data"Items do not show up unless i start removing family table items from browser workspace.Here are the errors that I facedServer error: Cannot retrieve family table neutral data"

This is a basic example of how to use the vbapi toolkit for PTC CREO PARAMETRIC (version 9.0.2.0). This also has an example of how LabView does the equivalent of a VB.NET " typecast " to parent and child objects in ActiveX using Variant To Data. Detailed documentation of the interface is installed with the Creo vba tookit at C:\Program Files\PTC\Creo X.X.X.X\Common Files\vbapi

This month’s challenge is on black holes! Create a worksheet that: Calculates the event horizon (Schwarzschild radius), last photon orbit, last stable particle orbit, and temperature if the Sun, Moon, and planets of our solar system were to become black holes. (You can choose whether to include Pluto.) Uses the Chart Component to depict the event horizon and temperature as a function of mass up to the size of UY Scuti, the largest known star in the Milky Way galaxy (which may become a black hole “soon” on a cosmic timescale).   Image courtesy of NASA Goddard Space Flight Center / Jeremy Schnittman used under CC BY-SA 4.0.   Considerations: How do you provide the inputs? Matrix, table, combo box input control, or other? When creating the Chart Component, does it make sense to use a log scale anywhere? The equations can be found here (hint: most are on page 36). Documentation (text blocks, text boxes, and images) for this challenge is critical! The math is actually not that

I am using Creo Parametric Release 4.0 and DatecodeF000I'm trying to make a .frm to use as a base sheet for multiple drawings. There is a section where some data will be manually input like height, weight, and length, and I'm trying to find a way to make other squares on the table auto spit out the metric version of the input data.For instance, I would manually input 50 (in) into the length and the table auto fills the square next to it with 1270 (mm).Alternatively, if set up parameters so the table would grab the weight (lbs) and then auto calculate the weight (kgs).I get that I need to use relations to do this but I'm unclear on how to do the relation.Thanks in advance.

I have been having issues with long regeneration times when I regenerate an assembly window or try to make changes/suppress. This occurs even when all parts/subassemblies are locked, I have auto_regen_views off and enable_auto_regen off. My coworker does not have this issue when working in the same assembly.      

when the user launches creo illustrate 7.0 is ask for the license path. The path is in there and correct however when you hit save it just keeps the license screen open and never launches the program.If i right click Creo Illustrate and select run as admin and put in my admin credentials the program launches without issue.Local users do have modify rights to the PTC license folder.    

I am using Creo Parametric Release 6.0 and Datecode6.0.4.0How set in Creo Parametric values for PPRINT parameters (for example):PLUNGE FEEDRATE & UNITSCUT FEEDRATE & UNITSRETRACT FEEDRATE & UNITSFREE FEEDRATE & UNITSAre these parameters set automatically by the values assigned in each NC sequence of feeds, or can they be assigned for each CNC sequence to the user, regardless of the feeds used?

I am unable to acquire the necessary license to run the PTC Mathcad Express (I want to try the full PTC Mathcad functionality for 30 days). Every time I attempt to activate my PTC Mathcad Prime 8.0.0.0 I run into the following error in the "Acquire License" tab: "You have reached the maximum number of license requests available for your product type."Furthermore, within the PTC Mathcad options tab, I get the following message:"2/15/2023 4:32:00 PM : The license request failed.Requesting MathcadPrime ...C:\ProgramData\PTC\Mathcad Prime\license\MathcadLicense.dat: (-10) Feature has expired."Any help debugging this problem would be much appreciated as I would like to do my free 30 trial error before deciding whether or not to update my account to Mathcad Prime 8.Thank you!

Trying to save an assembly to a network file share "Working Directory". There is a library that holds some of the components for the assembly here - C:\Program Files\PTC\Creo 9.0.2.0\Common Files\ifx\parts\prolibrary. When I save, I get the "error writing file, check disk space or write permission". No disk space issues, have read/write access to the network location. If I remove the local library parts, the assembly saves. What is causing this?

Hi allPlease, see the attchd.file.There is a graph where I would like to represent parameters x and y related to z.I have no idea how to define the x and y axis.Does anybody have an idea how to do that? Thx
