About MCDX
PTC rebuilt Mathcad as Mathcad Prime in 2011, with its own MCDX worksheet: equations, units, text, plots and pictures on pages, worked out as they’re typed. Engineers keep their calculations in it, and PTC’s free Mathcad Express opens and edits one too.
Inside, an MCDX is a package like Office’s files: the worksheet’s regions as XML, the results Prime last worked out in a part of their own, each text region as a document of its own and the pictures. A plot is kept as its settings, beside the points Prime last worked out for each of its traces.
Filepeek reads it in your browser and lays it out on its pages as Prime does: each equation typeset where it sits with the result Prime saved, never worked out again, its matrices cut to the rows and columns Prime showed, its programs, the text in its styles, the pictures and each XY plot drawn from its saved points. Zoom in or out, and Export saves the worksheet as PDF.

Questions
How do I open an MCDX file on a Mac?
Drop it on this page or choose Peek an MCDX. Its pages show as Prime lays them out, every equation and result in its place, on a Mac, a phone or any computer.
Are my plots drawn?
XY plots are, from the points Prime saved with each trace, in their colors, marks and axes. Prime keeps no points or picture of a 3D or contour plot, so Filepeek names those where they sit.
Are the results worked out again?
No. Each result shows as Prime last worked it out and saved it. Changing a value and seeing the results follow needs Mathcad Prime or Mathcad Express.
Can I save it as PDF?
Yes. Export saves the worksheet as PDF, a page for each of its pages, to share with someone who has no Mathcad.
