The examples using Solve Blocks show a plain box with Guess Values, Constraints, and the appropriate Solver inside, but the box is otherwise "undecorated". When I lay down a Solve Block, it has labels on the side for "Guess Values", "Constraints", and "Solver". If I remove unneeded space inside the Block, the labels on the side "ride up" so they overlay each other and look just plain ugly.How do you suppress these labels so that the Solve Block looks like the blocks in the Help Files, i.e. just a box with no labels? I looked and couldn't find it in the Ribbon (I may just have missed it), and right-clicking or left-clicking the Block didn't seem to work (unless I failed to find the Magic Spot).

As per the original Post.    I believe I have the premium version of Mathcad PTC Prime 9 - but "ctrl" + "enter" never worked for me either.    Actually, as far as I know, I have Professional version of Mathcad PTC Prime.  M > About > just says I have Verison Prime 9.0.0.0.  I pay something like $600 a year for the license.    Anyway "ctrl" + "enter" doesn't work for me for whatever reason.

I successfully converted a number of .mcd and .xmcd files to .mcdx files in the last 2 days. (using Mathcad Prime 9.0 in the Mathcad Express version, but with 26 days left in the free trial period ) My computer updated and restarted last night (Windows 11). Today, the .mcd files I have attempted to convert have failed. The xml log file for 1 conversion said "Could not start Mathcad conversion process. Check that .Net Framework 3.5 Windows Feature is enabled". I enabled that feature in Windows (following the Microsoft instructions), and restarted the computer, but subsequent conversions also failed. The same message is in the .xml log file of the conversions attempted after enabling the NET Framework. I have attached the xml log file and the log.txt file that were produced in the conversion process. Thank you for any help that can be provided.  

I know there is a wrap feature like:   But is there a feature to get the answer at the bottom of the equation - like: Thank you.  

I may be asking too much, but I have a general question about using the root function in a series of variables and constants.  For example, how can I program the following in MATHCAD 15 to find the roots xi of the function Fi wherei=1…5Fi = (1+Ki*xi)*(xi*cot(xi)-1) + BKi = known constants for all iB is known constant  Thanks for any help.Reg

I have hundreds of MathCad 13 files and I can't start MathCad from one hour to the next. Is it possible that this data is lost forever? That would be a disaster for me. Please help me!   Translated by the Community Moderation using Google Translate     Ich habe Hunderte von MathCad-13-Dateien und kann MathCad von einer Stunde auf die andere nicht mehr starten.- Soll es möglich sein, dass diese Daten für immer verloren sind? Das wäre für mich eine Katastrophe. Bitte helfen Sie mir!

to all Doing a sanity check on the CFFT for another spectrum analyser in a 1/3 party toolIf one has a sine wave Asin(w*t) then a spectrum analysis will return an amplitude a=A/2 at w (or f= 2piw) . Am I correct?Therefore if one only has the spectrum as an output (and not the original time signal) then one can read the frequency (w or f ) and conclude that the sine wave at the freq (in the time signal )has a peak value 2a! Thanks in advanceJohn

I'm trying to get a programmed text output from testing if a point is inside a circle.  All of the points are either secondary ohms or degrees.  The chuck of programming seems to fail if there are units attached to the numbers.  See Below.   

Hi everybody,I have calculation sheets that utilize a reference to a different sheet that contains subroutines to calculate coefficients, factors etc. for the main sheet.In Mathcad 15 this works just fine, in Mathcad Prime 9 however, an error message (see attached image) is returned by Prime, claiming that there are errors in the calculation sheet.Has anybody figured out how to find these errors? When I open the Prime sheet no indication is given that points to the error. As I said, the sheet works in Mathcad 15, so I assume that the calculation is ok.Any ideas?Raiko   

I had a circle function that was working fine until I re-defined some of the variables as Ohms-secondary.  The plot is blowing up now and I'm not sure why.  See attached.  

I am having trouble with the onefn function in Mathcad 15. I get double entries in the 1/f noise vector and if I take the CFFT(ofn) I get a zero as the first result. Also I do not understand the mirrored magnitude plot of the 1/f Noise. I also don’t understand why the range variable even starts at zero. That would give infinity for 1/f.

Hello, @ttokoro  How to plot arrow lines like below in 2D and 3D:      

Hello everyone,I have something to ask, and maybe it's quite easy to ask. But I couldn't find any source about it. I created a chart from curve fitting, and I want to see the chart values in a table. If it's necessary, I can add the file. 🙂  

Hello everyone 🙂 I want to do exponential regression, I saw a YouTube source about it. Link https://www.youtube.com/watch?v=O0LbLATVboU&t=320s. However, I face some errors when I want to choose some value in a matrix. The error shown in the figure below pops up. Error: This array index is invalid. The index must be an integer, not less than ORIGIN, and not greater then the last element. Can you help me?  Note: I attached the Mathcad and Excel files.    

Hello Everyone.From :   How to plot an Arc in 3D with Mathcad 15 ?Thanks in advance for your time and help.Best Regards.Loi.

This should be simple.  I have an issue where I define an equation and get a useful result.  But further down in the mathcad sheet I just need to echo the equation that defines the variable to the user so he can make other determinations from the equation.  How do I do that?  See attached. I need the means to do this in Mathcad 15 and in Prime 8.0.     

How can I plot a circle in the X-Y plane, only knowing the radius and location of the circle center?I have Mathcad Prime 8.0. 

Hello, I can't get the two terms to add up. i can get the results individually. Attached is Mathcad 15 sheet. Thanks    

Is there anyway to display the result?  I'm using ptc mathcad prime 7.0.0.0

I spent a fair portion of my career taking measurements of experimental data.  When I first started the senior engineer would review the data and discard measurements that he deemed false.  Discarding data simply because you thought it was wrong struck me as very questionable and I spent a fair amount of effort developing a method (using T statistics) to identify "bad" data.   It turns out that there is a statistically rigorous calculation to do just that, developed (and published in 1852) by Benjamin Peirce.  That method is developed and demonstrated in the attached Prime 4 Express file.   Thoughts and suggestions?

Estou encontrando problemas para abertura do Mathcad. Estava usando normalmente, mas de repente o programa começa a carregar e não abre. Já reinstalei e continua da mesma forma. Qual orientação para corrigir este problema?

Hello Everyone.From :How to plot the Fermat point of a triangle with Mathcad ?Thanks in advance for your time and help.Best Regards.Loi.

Hi experts,  this is my original equation, and I want to do the differentiate for every variable and simplify. but, I can only do it one by one, I think it takes me too much time if I have more variable in the equation. I would like to know any other methods could help me do it quickly. the attached file version is Mathcad 15. 

Please can you help me.I bought a single user MathCAD liscence many years ago, from Adept, but have since then always had a work mathcad tool available. I have been a heavy MathCAD user and supporter in my career and still am.I am now planning retirement and wish to continue to do some work in engineering, to support a disabled peoples charity, so need occational access to mathcad again.Please can you locate what type of licence I have and advise me how to gain access to the tool again.My address would have been 21 Yeldham Lock, Chelmsford, Essex, UK. when the licence was bought and worked for Marconi / GEC...Many Thanks, Robert 🙂

The installation files for my Mathcad 15 files are for M010 which is not supported by Windows 11. Does anyone know where I can download the M050 version?
