Tuxpaint cad?

Tuxpaint can be good for drawing pictures, cartoons, and the like, but if we let it stretch it's muscles there is more that can be done. Maybe use it as a sort of drafting program. A drawing usually has at least four views. They are the front, side, top, and isometric (roughly translated at an angle).  If you needed a simple step stool, you certainly can make a drawing to reflect that. In this case you only have a partial isometric, but the point gets across.

Circuit design.




Have fun.

You actually can do a minimal windowing from the command line in Linux with dvtm. Dvtm is excellent for low end machines where graphics are not a priority. In the picture shown we have a working clock, SC a spreadsheet that you can easily export data to your favorite desktop spreadsheet such as Libreoffice, Links2 a web browser pointed to www.google.com, and finally nano a pretty decent basic text editor. I prefer vim, but nano has more of a user interface. Cheatsheet: `dvtm` is one simple, easy-to-use terminal multiplexer. Commonly used Options:     -v         prints version information to standard output, then exits.         -m <mod>   set default modifier at runtime.         [cmd...]   Execute cmd after dvtm is started. KeyBoard Shortcuts:     Mod    Each keybinding begins with Mod which defaults to ^g but can  be               changed in config.h or with the -m command line option.                       Mod-c  Create a new shell window.            Mod-x  Cl
