If you want a luxury numerical calculator, with reasonable 2D plotting facility, then Prime Express is OK. The difference between Prime 5 and 4 is a third-party 2D plotting tool that uses a different paradigm compared to the 'native' plotting tool. I've seen PTC promising more than it actually delivers, and it spits out later than it promises. In over 10 years, PTC have managed to bring out 5 'major releases' of Prime, where the new features included with each release got smaller over time. Some bugs reported for Prime 3.1 are still not fixed. However Prime results in an enormous penalty in speed (starts slow, equation entering is slow, calculation is slow), functionality (lacking features that Mathcad had) and price (you get to pay a yearly subscription, you cannot get a perpetual license for a lifetime anymore). You get to use a limited version of the full Prime for free, for ever (PTC promise). Automatic variable/unit/function/constant labelling (though brings some problems every now and then),ģ. Prime brought a few improvements over Mathcad. They started development of 'Mathcad Prime'. Very soon after that, they decided that Mathcad-as-we-knew-it was not the way to go. PTC acquired Mathsoft (and with that: Mathcad) over 10 years ago. *.mcdx files can only be created with Prime. In the latter case you can additionally install Prime 5 using the same license. As your file is in older Mathcad format, you either have only a license for real Mathcad or, more likely, you own a license for the current Prime but have only installed the older (and better) Mathcad (presumably version 15). > On the other hand our Dept has a full license, and seems unable to generate mcdx file.Ī full license of which software? If its a license for Prime its also valid for Mathcad 15. Their Prime Express (I assume current version 5) is able to read any file created with Prime 5 down to Prime 1 (*.mcdx), but it will not read files created by real Mathcad (Mathcad 15 or below, *.mcd, *,xmcd, *.xmcdz). > My students are prevailing themselves from the "student" version MathCad Express, can it only read one format but not the other? So your students may use the trial periods of Mathcad 15 and Prime to be able to convert older worksheets on their own. After that trial period it stops working (while Prime false back to the limited Express mode). T hat's pretty amateurish but thats the way PTC has decided(?) it to be.īTW, you can also install Mathcad 15 and it will work with full functionality (including the ability to convert older sheets to Prime format) for 30 days. Any version of Prime should read any Prime file created with it or any earlier version but its not able to read files in format Mathcad 15 or below.įurthermore there is no way a file in format Prime 5 for example could be saved or converted to older versions format - not to Prime 4, not to real Mathcad 15 or below. I may add that Mathcad (that is version 15 and below) can of course read any file from any older version (even from the DOS era I guess) and MC15 is at least able to save in older formats back to MC11. ![]() The original Prime file can be seen, but once it's modified a lot of things will no longer work. (A trial version of Prime will be fully functional for 30 days, then become Express. Prime Express is a limited free version of Prime. ![]() A full license of Prime entitles a copy of Mathcad 15 be installed on the computer and will run under the same license. It will interpret the old file and attempt (often very poorly) to create a Prime version. No Prime can read a file from "original mathcad." There is a converter that comes with Prime it requires a functional copy of Mathcad 15 be installed and useable on the same computer. ![]() Version 4 can read any earlier version but cannot read a version 5 file. Version 5 should be able to read any **.mcdx file. (Open an **.mcd file in version 15 and it will open properly save it and it will save as **.xmcd. **.xmcd files are also "original mathcad" files but from a more recent version. Any Mathcad (version 15 is current) not Prime should be able to open them. **.mcd files are "original mathcad" files from an old version.
