This is embarrassing to say, but I believe in simplicity. Version two or TCW 2 from about 1995 suits all of my needs perfectly and does work on Windows 7, perfectly on XP and earlier and will print drawings.
I did buy vsn 3 and maybe 6. Both will convert TCW 2 to those versions, and those versions will convert to vsn 10, which I also tried out.
The dxf file converter for TCW 2 does not work with later versions of TurboCad or AutoCad.
The computer I just bought is 64 bit with the Intel i7 quadcore & 8 GB of memory. I bought it to run a video editing program called Cyberlink which is very resource demanding. If TC2 works on this, it will be like running a Model T along side a new Rolls Royce.
I’m actually animating TCW 2 files to make a movie.
I did the majority of My work in TCW v4 and some of the finish work in v5, primarily for its 3D capability. I purchased the occasional newer versions as they came along when I felt they added more functions or better 3D modeling that I could use on various project. I believe I got v4 to work in XP, and v7.1 works natively. Haven’t yet tried OrCAD or AutoCAD in XP.
The .dxf and .dcw converters in v4 and v5 were upgraded and worked much better than previous versions, although sometimes it was simply a matter of adding some CAD fonts for a successful conversion.
TCW v4 works well in Linux running under WINE, and prints as long as you already have the cups and lpt files configured to print already. If linux can print to your particular model, TurboCAD will print. At the most, I have had to convert a drawing to something like a pic file and print it that way using gimp or in OpenOffice, usually when I have not yet configured the printer.
