Possibilities of Tabes in Mathcad - in Comparisson with Excel

I also have a few other questions: 1) The mathcad I have installed is Prime 2.0. It saves teh data with a mcdx extension. I can not open mcd extensions created in a previous version of mathcad. Is my data lost?

Its not lost, but deep buried 😉 No, honestly you cannot open older mathcadsheets directly in Prime as we are used from any other decent software. You have convert it first. The conversion program is installed along with Prime2 and you can call it as a separete program or from within Prime. Go to Ribbon "Eingabe/Ausgabe" (guess we both use the german flavour here in Austria:-) and select "XMCD-, MCD-Konvertier". You have to be aware that you must have the lastest version of Mathcad15 installed to make the conversion to work - I guess the 30day trial will do while I am not really sure about that. The conversion is possible only in this direction, there is no way to convert Prime sheets into the format of older Mathcad versions. The conversion itself often fails and the regions where something went wrong are marked in the Prime sheet, The reason for this is that Prime does not support all features of prior Mathcad version. Politely said its still a work in progress.

2) Is it possible to crate pdf outputs from mathcad?

No support from Mathcad here, but you can create fine pdf-files by using one of the many available pdf-printers. Free versions (amongst many others) are pdfCreator or cutePDF, commercial versions include pdffactory or, of course, Adobe PDF creator.

3) Is it possible to create a sheet format with frame, logo, etc, etc....?

In Mathcad 15 and prior - yes. Mathcad Prime does not support template files and does not allow much variations concerning page formatting. You will create your sheet with your logo etc. (no support for date, filename, page number, though), save it and use and rename it for every new project. Uncomfortable, but a least a way to do it.
