I would like to request a temporary evaluation license for Mathcad 15 to perform local compatibility testing of a software integration demo. I already have the Mathcad 15 installation package, but I do not have a Mathcad 15 license. I have completed testing with Mathcad Prime; however, its trial license cannot activate Mathcad 15. I now need to separately verify compatibility with Mathcad 15, including opening and saving legacy worksheets, modifying input variables, recalculating worksheets, and retrieving results through its automation API. I understand that Mathcad 15 has been discontinued and that the previous trial licensing links are no longer available. Could you please confirm whether a short-term evaluation license can still be issued for this purpose? If not, please advise whether there is another authorized way to carry out this compatibility testing. The requested license would be used solely for local development and evaluation, not for production deployment. Thank you f

Attached is a zip file containing a large matrix in a solve block.There are two questions in yellow boxes.  Any help is appreciated.The jpg file shows the geometry of the diffusion equation problem.

Hello everyone! I need to minimize an objective function, but the algorithm fails to converge. I have tried changing the initial conditions several times, yet nothing changes. Given the extensive experience of the members of this community, I would be very grateful if someone could help me solve this problem. Thanks again. Best regards.

I have inserted a table from excel and i now want to add the values from two of those columns together, but i keep getting the error value must be a scalar or matrix.  

Hi guys,I’m working in Creo 12 and I do have some tables and BOM tables, and I'd like to change their anchor point. By that, I mean the position of the mouse cursor when I place them using "Table from File". I like to have it in the complete right bottom.I've already tried changing the growth direction, but unfortunately that doesn't solve the problem.Any ideas on how this can be changed? Growth direction of the table via “properties”Location of the cursor when adding table from fileWhat I also have tried to do, is:first create a table with only one cell change the growth direction to the right bottom corner   A table with only one cell and the direction from the right bottom corner add some columns on the left and a row on the top   Adding columns on the left of the first cell save the table when I add the table via “Table from file”, the corsor is at the top left corner of the first cell: Location where the cursor is when adding this table (started with only one cell)  So this wasn’t

This month’s challenge has a civil engineering theme – actually, a bit of an ancient civil engineering theme related to my adopted home of Valencia, Spain. One of its most famous landmarks is the Torres de Serranos (Serranos Towers), one of the last remnants of its medieval wall:Torres de Serranos in Valencia, SpainIn this challenge, you will perform some of the same calculations that master builder Pere Balaguer worked on in the 1390s. Except, of course, you have the benefit of modern software for engineering calculations. Specifically, you will perform analysis of the Gothic arch at its entrance:Gothic Arch Gate Entrance to the Torres de SerranosDimensions and assumptions:The arch is a classic three-hinged arch mechanism. The span (horizontal width at the opening) is 6 meters. The height from the spring line (where the arch transitions from vertical support and begins its inward curve) to the apex hinge is 4 meters. It carries a uniform dead load from the floor above of 45 kN/m acros

I created a user account, but when I try to install PTC Mathcad Express Prime 9.0.0.0, I receive this message: "You have reached the maximum number of license requests available for your product type." How can I resolve this?

Hello! I am in the process of interviewing at PTC and it would really help me if I could get some real customer feedback about Creo. I am looking for the strengths and weaknesses of the product. All levels of experience with Creo are welcome to answer! Thank you for the help!

Hey everyone,I have searched through some of the discussion but I don't really understand the code that has been thrown around. I have three map keys set up in my config file. The first is ft and that opens my family table. The second is od and that opens my drawing and gives me a front cross section view, a right view, and then an iso view in the top right corner, I then pause to pick my instance and fill is my prompts such as details, date, drawn, by, part number, etc. I then use d to open the dimension tool and dimension the drawing. My question is how to I get my drawing file to open and be saved as the same name as the model file through my map keys so I don't have to go in and rename every drawing that I do? I tried to follow some peoples codes and put them in my map key code but then everything messed up. I also would like to get my drawing number box in the title block to be the same name as what the drawing and model are named. I'll attach a copy of the map key code I am runni

Using CREO 13. I always design in mm, all my files are set up like that.When I export a sheet metal flat pattern however (via the new direct export feature in CREO 13), the resulting DXF is inches (and the part is huge).I noticed the DXF contains the following string:$INSUNITS 701  0The “1” is the file setting to inches. Should not be like that.I don’t know where it comes from.I have my config.pro set up as following:pro_unit_length unit_mmdxf_out_scale_views yesdxf_out_drawing_scale yesI also noticed I have a dxf_template.drw. When I open it I notice drawing_units is set to “inch *”, but when I change it it immediately goes back to “inch” when I recheck, so I can’t set it. Not even sure if that file has any relevance. Also checked some iso.dtl file, which is has drawing_units set to MMI’m out of options right now. Any ideas?

The PRT which is the drawing based on has International System units (mm) settings. Whenever the generated DXF is opened, the Creo 9 drw convert dimensions from mm to inch and it is not intended. I'm not being able to find conversion in the drawing module. Don't know if the conversion occurs in the DXF exportation or in the drw generation from the exported DXF. Thanks

I am a student  and ordered Mathcad Prime 12 Student Edition. I verified that my credit union account was charged. I followed all of the linked steps in the email I received and got an error message: Access denied - Insufficient Privileges Our records indicate that your company does not have a current PTC Global Support agreement I have phoned and emailed Cleverbridge and have not had any luck in getting them to fix this issue. They incorrectly believe I have a billing problem which I do not! I am unable to speak to anyone at PTC about this because of the logic of your automated phone answering service.

I’ve recently gotten my hands and mind around Pro/TOOLKIT and have been developing a series of add-ons and tools to improve the Creo experience:Open the drawing associated with the active model Remind users to save their work (based on timer) with button to do so Warn before saving a model in a newer Creo version, with options to cancel or continue Detect a circular reference immediately and warn the user with undo what caused it Show what changed in an active model since the last save Detect weak dimension before finishing a sketch and warn userI’m considering making these available through my GitHub as a set of utilities to extend Creo. What other ideas or needs do you have? Would any of these be useful to you? No TOOLKIT license is required to use them. They’re simple add-ons enabled through a configuration option.

We have native legacy CADRA .cad files and need to convert them to pdf or similar. Is there a compatible viewer or conversion method?

I’m new to Creo Schematics and currently using version 7.0. Every time I open the software, the schematic background appears black. I can change it to white manually, and it works during that session. However, when I exit and reopen the program, the background switches back to black. Is there a way to permanently set the background color to white instead of black?

Hello Everyone,I’m still a beginner in Creo and really need your help,Can someone please guide me on how to get an helical sweep to follow the surface in the pictures below?It works with when selecting Constant but it doesn’t work when I switch to Variable 

Is this no longer possible?It tries to attach and then disappears from the attached files.I am using an iPad.

Experts, I am exploring how to leverage the Mathcad COM API to automate for different  workflows:For already existing worksheets how can I start accessing worksheet content and extracting variables and their calculated values for further processing or integration with other applications (this can be any application). Also, Is it possible to generate Mathcad worksheets and reports from scratch using the API, including creating and populating both text and mathematical regions through code?I would appreciate any recommendations, workarounds, or alternative approaches for achieving these automation requirements using the Mathcad COM API or other available methods.

I recently deleted Creo after having several problem codes (-9) and thereafter (-1) which came out of the blue. I tried following recommended steps, but after these didn’t work, I deleted Creo and every file related. When trying to download again, everything goes smooth until I try to install my university license, where it simply says “ERROR” under the license. I am now just a bit lost, and can’t find any solutions to the problem.

Hello, After many years not using Mathcad, I wanted to load my old datasheet developed in Mathcad 15. I have set up the free version just to have a sense of “Whao.. I like it” but it turns that the converter is not working: no license but I have a license for 30days no?Please Is there someone to help? I would like to see if the Prime (mathcad12.0) fits my new needs. thanks!John

I have been using mathcad prime on my computer for engineering. Starting about a week ago, whenever I try to open the app, it opens a webpage to download the free trial. I have tried upgrading the app, uninstalling and reinstalling, neither of these have worked. The app still shows on the bottom bar but will not actually display the window. I am running matched for windows. What should I do?

Hello Team, We recently migrated our current Mathcad license server. Due to the configuration changes associated with the migration, the existing license is no longer working. Could you please support us in issuing a new license file? Also, please let me know if I need to raise any request or provide any additional information for the same.

I’m using the new flat pattern dxf export feature in CREO 13 and so far it is working very good.However to further automate my workflow, I would love to include the thickness and possibly the material in the filename.In the export dialog, I tried setting the file name to:&model_name_&smt_thicknessbut that gives an illegal characters error. Is there any way to do this? Additionally it would be convenient to export any parameter as text like you can export width and length currently.
