Improvements to Explicit Function

Improvements to Explicit Function

1. Describe your environment: What is your industry? What is your role in your organization? Describe your stakeholders. - I am a bridge engineer for a provincial transportation department.

2. What version of Mathcad are you currently running?

3. Describe the problem you are trying to solve. Please include detailed documentation such as screenshots, images or video.

The explicit function is un-usable for most of my work as you have very little to no control over how many decimal places will appear and the units that will be used. The current function results in eqns that extend off the sheet because several variables go to 10 decimal places. Making the font size smaller doesn't work because it is so long.


As well, many eqns we use are long, so restating them prior to the explicit function uses up a great deal of space. If the input eqn and the explicit function itself could be hidden, that would be helpful on cutting down space.


I have attached our bending resistance calculation with the explicit function as well as our current practice or restating the variables. Even breaking the eqn down into smaller terms the explicit function cannot function.


4. What is the use case for your organization?
Whenever we complete engineering calculations and they are pdf/printed and reviewed by another engineer line by line. It would make the review process much more efficient if the reviewer could see the values of the inputs into eqns, similar to how one would complete hand calculations. 


Once reviewed, the work is stored, as a paper copy, in our file room for future use.

5. What business value would your suggestion represent for your organization?
Reduced time reviewing calculations as you can quickly verify the inputs are correct and so that someone referring to the paper copy 50 years from now (our structures have a life of 100 years) can easily follow them long after MathCAD has moved onto version 50.

Time would also be reduced as currently we have to restate all the variables that were used under the eqn.


Right now we only have a couple mathcad licenses, being able to do this would help get some of the more hesitant engineers on board so we can expand mathcad's use in our department. 


@JM_10452409 I totally agree and appreciate your formulas as I am a fellow structural.  Personally, I feel there should be a way to simply show iterations of a formula--first by substituting variables with their values, then show following iterations. 


When doing it by hand I usually like to skip to the step before adding up all the terms (like in a combined stresses check) so that you can see which term controls.

And sometimes the input variables are several pages back or has been redefined so showing the first step where the variables are replaced with their values is very useful. I try to keep my input variables in sections so it's easy for a reviewer to follow when printed on a PDF, but I have received calculation packages where things were so messed up that I could not find the variable definition (so frustrating).


I find that Mathcad Prime is still tailored for mathematicians and academics, not run-of-the-mill real world engineers like us.

Hi @JM_10452409!

Thank you for your idea. Based on the information you provided, we are acknowledging it as the Community management team. This is not a commitment from the Product team. Other users may comment and vote your idea up.


I'm facing the same issues and I'd love to have more formatting options. We're using the 4-eye principal in our company and it vital for checking that you can read equations in natural, mathematical notation. Unhidable key words, ten digit decimal places in symbolic evaluation, Matrix brackets that look broken, etc. is an anathema to PTC's own statement.

Prime is touted as, quote "Show your work using rich formatting options alongside plots, text, and images in a single, professionally formatted document." unquote, their approach is not very professional.


Thanks for the comments. Good to know I am not the only one who would like to see this improved.


"natural, mathematical notation" is a perfect summarization of what I would like to see implemented.
