3D plots do not work with Mathcad 14 on Windows 8. What is the best free software that can be used easily to import a matrix from Mathcad and create and export a 3D plot to display in PowerPoint?

If you've got PowerPoint (?), then you could export it to Excel. gnuplot seems to be well regarded and is free. I know a couple of applications use gnuplot as their plotting package. If there's a dll version of it then it might be possible to insert it as a scriptable object in Mathcad.

Thank you, Stuart. I tried GnuPlot and SCaVis. Both are for computer and Java geeks. I want something as simple as Graphing Calculator 3D is (or as Mathcad was), but with the ability to import and plot directly from large matrices. I would even be willing to pay, say, $100, but not $400 to $1000, which is what big graphing packages cost.
Excel, FreeMat, and R come to mind, but there are some others.

David,
Thank you for this information.
More specifically, I've got an 8000-element vector at 64 successive time steps, that is, an 8000x64 matrix, to display in a surface plot or contour plot, using Windows 8, Mathcad 14, Excel and PowerPoint, and whatever other software I need. What else do I need?
Can you save the file in csv or Excel format and use the 3D print in Excel?
Stuart
Yes, the Mathcad prn file can be opened in Excel, and a 3D surface plot can be generated by Excel. Formatting options are extremely limited. And with thousands of points in one direction, the graph is squeezed in the other direction practically to a plane, and can't be expanded by more than a factor of 20. When the 3D plots were working on Mathcad, there were loads of formatting options.
