CAD

Dear PTC Mathcad Community,I want to ask for clarification on the behaviour of units and symbolic substitution in Mathcad Prime (similar topics have already been raised, but I still haven't found an appropriate answer for my issue). So I try to find a symbolic expression for epsilon_c2, which is a parameter of the equation N.Solver succeeded with the issue, but with incompatible units (see picture)So, I have tried to find out the solution in the community, but the advice of @Werner_E  with calculation options didn't resolve the issue (see the picture)So my issues are: 1. How to make the symbolic solving more "seamless" with appropriate units' manipulation in the solutions?2. Why does Mathcad not see the assigned values of the  epsilon_c2 obtained in the previous solution? After some time, when the file has been refreshed, some magic happened, and now I can use the roots of epsilon c1 and c2 in a "normal" manner.But the next issue is that it doesn't let me

I am trying to upgrade my PTC account so that I can download MathCAD, but am receiving an internal error message when I submit the upgrade request with my customer number and site number or sales order number.

I have two vectors .. ztop and z ztop shows the depth of each layer (cumulative value of z in each layer) . ztop  has 11 valuesz shows points in that depth .. it approximately increases by 0.02 in each layer. ( it has 3670 values) each layer has its gamma and its ztop .. ( both have 11 values)what I need is to write a program that will repeat gamma values for each z so I get the 3670 gamma values . In the first layer instead of having one gamma( 17 kN/m3) one value for all the layer , I need to get a vector which repeat this gamma as many as z in this particular layer .. and do the same for the rest layers. Can you help me with that? 

Recently, I was in the position of trying to explain to a 6- and 8- year old how to play the board game Battleship. (Kids from my generation had commercials that seemed to explain the basics of the game fairly well.) While trying to explain the concept of the grid to them and search algorithms, I couldn’t help but wonder, “How could this be done in Mathcad Prime?”     This month’s challenge, should you choose to accept it, is fairly open-ended: simulate various aspects of the Battleship game in Mathcad. Here are some suggestions:   Write a program that will place the ships on the ocean grid. The ships must be placed horizontally or vertically; no diagonals. Ships can’t overlap one another. Do you place the ships randomly or according to some kind of optimized algorithm? Alternatively, can you use Advanced Input Controls to allow the user to place the ships on the ocean grid? Display the placement of the ships using the plotting capability. Write an algorithm for

Hello, everyoneWhen adding the "search_path" option in the Configuration Editor, if the path contains spaces, Creo+ crashes with a “fatal error encountered”. The crash results in EXCEPTION_ACCESS_VIOLATION. The Creo-generated traceback log file is attached for reference.Paths containing spaces are expected to be supported. This behavior worked correctly in Creo 7.0 and is consistent with PTC official documentation, where examples of "search_path" usage also include paths with spaces.In our environment, removing spaces from folder names is not a viable workaround, as we are using corporate directories managed via OneDrive, and the space is part of the root-level folder name.As a result, this issue causes significant difficulties when manually defining paths for multiple subassemblies (up to 10 in our case) and standard components. Since I work with multiple projects daily, repeatedly locating missing components is inefficient and negatively impacts productivity. I would l

Hello Community, we are facing an issue with Creo Elements/Direct Modeling 20.7 + Annotation connected to Windchill+. When creating a new drawing from a 3D model (e.g. model name TEST) and saving it to the Windchill workspace, the drawing receives the correct Windchill number (e.g. CAD0000403) according to the OIR.However, in CED Annotation the drawing name is not updated – it still shows the original model name (TEST). In the TRACE log we can see that the number (PTC_WM_NUMBER) is correctly transferred from Windchill to Annotation, but the expected macro (Docu_set_drawing_no) is not executed. On another CAD workstation running Modeling 20.6 with Windchill 12.1.2.5 (on-premise) the drawing is renamed correctly, which corresponds to the standard behavior of the CED–Windchill integration. So far we could not identify a configuration difference. We also checked PTC documentation but did not find any known issue related to this behavior. My questions:Has anyon

As the title says. I want to learn all the functions available to be used in repeat region filter and relation. The documentation here is very limited https://support.ptc.com/help/creo/creo_pma/r12/usascii/index.html#page/detail/About_Writing_Relations.html#Arguable it's just the introduction to what the relation does. But does not give full details of what all functions are available. I've seen in my company people using much more advance relations to filter items in repeat region. I took the Creo authorized course some days back but sadly the instructor kept it just on high level and struggled to provide solutions for complex filters.How can I learn more on this, something that is comprehensive and all inclusive.

Hello, I have multiple points like this : And i would like to "visualise them" for a demonstration like this :  Is it possible ? Thans in advance

All, I have seen posts where family table instances cannot be deleted from Windchill when I delete entire table of the generic. Those deleted instances are still tied to the generic and cannot be deleted. I think I read something about purging the itterations below the latest version. Not sure how to do that. Anyone know how to get rid of these dead instances? I am thinking, maybe if I had the instances in session, then deleted the table, the saved each instance, that may have been the way to go? Wayne

Is anyone aware of any compatibility issues with Creo 7 (and/or later) on the new NVIDIA RTX 5000 Blackwell GPU's?

I want to use Python scripting in MathCAD Prime 11, but upon selecting python in the dropdown menu in the advanced controls editor, MathCAD hard crashes. I don't even get a chance to press "apply" or close the dialogue box. Everything closes. There is no stalling or freezing. It just crashes instantly. No error message is produced. What is going on? How do I fix this? My understanding is that, if Python shows up as an option, MathCAD has registered to appropriate location for the python executable. Is that correct? Python version 3.9.18 Steps. 1. Start MathCad with blank worksheet.2. Insert Advanced Control "Text Box"3. Name variable "aaa0" (or anything really).4. Right-click on the text box and press "edit"5. In scripting language drop-down box, select Python6. Watch MCP 11 crash.

I've saved the file on Mathcad Prime yesterday and today it's unable to be open. Unfortunately no restore file has been saved. Are you able to help with restoring the file?

Hi everyone,  Almost every design and manufacturing company uses some parts that are created by cutting some stock material (pipe, hose, aluminium extrusion, etc.) to a defined length without any other machining or other processing. Of course there is no need or sense in creating drawings for these kind of parts because the drawing would only tell what material to use and what length to cut it to. At the moment our method for handling these is by first modeling the part in Creo with any way the engineer is used to and then creating a WTPart automatically during check-in. Next the engineer goes to Windchill and adds a stock material WTPart to the structure of the new WTPart and sets the quantity of the BOM row to match with the length of the model.  Here is an example of the resulting WTPart structure: This is not a great method because if the length of the part is changed, it needs to be updated in multiple places: Model, part name and BOM row quantit

I am trying to find a good way to set a collision or avoidance region away from my fixture. Is this even possible within creo, or is everything just set automatically? I know you can't add the fixture as a check surface in any of the operations because it isn't the reference model. So where exactly can you configure your fixtures avoidance regions?

Hi,I have a problem that is sensitive to guess values. I am attempting to copy a method that was posted some time ago https://community.ptc.com/t5/Mathcad/Solve-block-problem-3-1/td-p/43434 but I get an error as follows:I am sure the fix is trival but I have a had no luck fixing it. Any help would be appreciated.ThanksRoss 

Hi everyone, I have created a part with two bodies and assigned a material to each of them. Now I want to control the material or its density for one body using a parameter in the relationship.Is this even possible? And if so, how? Or can I only control the overall density? I use Creo 8.0

Hi everyone, I have this function that I used to find R from it  Now I want to find the min, max and max  from it ..but didn't work .

Hi Everyone,Software: Creo Parametric 11.0.5.0. I am working on Migration of Weblink to Creojs. Here I am having doubt in the Topic "Enabling Security Settings" mentioned in CreoJS User Guide.  In my WebLink code, when I opened an html file, I will receive the below PopUp.  But as mentioned in CreoJS user Guide(please see below image), I am not getting any popup for security settings(like shown in above image) in CreoJS.Can someone help me to achieve this? Note:In both Weblink and CreoJs, my html file will be called from local folder only.Example: D:\PTC\Weblink\test.html Thanks 

Hey everyone,I am facing the issue that every time I create a new part file, the units are set to imperial in the model properties (first picture). I have changed the configuration file, so metric units are set as a standard (second picture). However, this apparently does not work. Does anyone know, how to keep metric units as default?I am using Creo 12.4.0.0Thanks and best regards,Julian   

Where can I download this tool? I have searched everywhere and can't seem to find it. The furthest I have gotten is: ENGINEERING.com | File Downloads but when you launch the installation launcher it asks for a password... I can't find it anywhere else. Any ideas?
