These free Mathcad Prime worksheets show how specific features are used and how to document engineering work. Download a sample to explore it in Prime at your own pace.
If you’re new to Mathcad, start with a short example on notation and units. If you have a task in mind, look for a sample that handles the kind of work you do, such as bringing in spreadsheet data or comparing design options.
Check which release of Mathcad Prime the example was built for. If the file won’t open in your version, you may need a newer release. When a download includes supporting files, keep them together after extracting the ZIP.
Before using a sample on a project, check its assumptions and verify the results against a trusted reference.
Choose by the work ahead. Learn how a worksheet is organized, build a model around data or design constraints, or set up calculations you expect to run again.
A short physics problem shows where given quantities, equations, and results belong in a worksheet. Start here if you want to see how someone else could read your calculation from top to bottom.
Try thisChange one input and trace which expressions update.
Download ZIPThis Prime 9 example shows how notation and units travel with a calculation. It is a useful starting point when a specification and a test report express the same quantity in different units.
Try thisPresent the same result in another compatible unit and check that its physical meaning stays the same.
Download ZIPFour examples show numeric and symbolic changes in Prime 7 through 10. Use them to distinguish calculations that evaluate to a number from expressions that preserve variables for further analysis.
Try thisCompare the example with the release it was written for before drawing conclusions about current behavior.
Download ZIPCompare the Excel Component and READEXCEL using the supplied workbook. The example is useful when measurements are maintained in Excel and the calculation that uses them needs to be documented separately.
Try thisExtract both files into the same directory and trace a known workbook value into the worksheet.
Download ZIPThe two examples explore pipe diameter and a piston-head profile. Together they illustrate two different modeling goals: finding a value that meets a requirement and comparing designs against an objective.
Try thisIdentify the unknowns, constraints, and objective before changing an input.
Download ZIPThe fuel-economy example relates selected factors and their interactions to a measured response. This approach helps when a test program needs to investigate several settings together.
Try thisCompare the interpretation of a main effect with the interpretation of an interaction.
Download ZIPAn RLC circuit example uses a loop to evaluate impedance across a frequency array and plot the results. The same pattern applies whenever you need to run one calculation across a range of operating conditions.
Try thisChange the frequency range and check how the curve and its units respond.
Download ZIPA raffle example combines a data file, random sampling, and a loop. It gives you a small model for understanding how a worksheet turns a list of eligible entries into a selection.
Try thisRecalculate to see how the selections change, then inspect the input and selection logic.
Download ZIPThe collection pairs Python and JScript versions of six worksheet controls. These examples are useful when the same worksheet will be used by people who need to choose an input without editing the formulas.
Try thisCompare how one control passes its value into the worksheet and check your release and scripting setup before running the example.
Download ZIPStart with the decision your calculation needs to support. These examples show what to gather before you build the worksheet and what result to put in front of a reviewer.
Size a shaft for a given duty or compare two materials under the same load. Record where the load acts and which failure mode governs the check.
Compare how a filter responds across its operating band. Use the same source and load assumptions when comparing component choices.
Compare beam sections under a defined load case. Document the support conditions and load combination so a reviewer can reproduce the demand.
Compare a motion model with a measured trajectory. Define the coordinate system and positive direction before comparing the predicted and observed curves.
Set up a material balance around a mixing vessel. Define which streams cross the boundary and whether the vessel is accumulating material.
Fit a calibration curve to measurements taken across a known range. Inspect where the fit misses the observations before using it to estimate another value.
Choose a representative problem and agree on the reference inputs and results before you adapt an example for your team.
Adapt a sizing method for a machine family. Review an ordinary configuration and one at the edge of its operating range.
Explore Industrial machinery
Use a circuit or thermal worksheet to compare operating cases. Record the input source and the assumptions a reviewer needs to reproduce the result.
Explore Electronics and high-tech
Pilot a previously reviewed calculation. Keep the source inputs and baseline results with the working copy so a second reviewer can trace any differences.
Explore Aerospace and defensePlan what to download, what to check, and when to ask for a review.
The linked example archives are free downloads. Opening, editing, or running every feature depends on your Mathcad Prime release and license.
The file may have been saved in a newer release. Check the example’s version and use a compatible Mathcad Prime installation. Older MCD or XMCD files use a separate conversion workflow. Explore Mathcad migration
Extract the archive and keep companion files with the worksheet. The Excel example needs both the worksheet and the workbook in the same folder.
Some examples rely on features beyond the Express edition. Check the feature requirements before choosing an example for your installed edition. Compare Mathcad capabilities
Work from a copy. Verify the formulas, units, assumptions, and results against a trusted reference, and follow your team’s review process before relying on it.
Start with a representative set of inputs, an expected result, and the decisions your reviewers need to trace.
