Xfig

Xfig is a CAD program that permits you to draft figures (like Autocad or Microstation). The Octave procedures included in BSU often provide the option to save plots in Xfig format. In particular, the plotting sections have scaling options for both Xfig and Postscript. It is possible to control the axes lengths in desired distance units on a printed page. It is also worth noting that Xfig is a valid device format for the PLPLOT library. That is, all you need to do is change the device definition in a BSU code that uses Postscript, and it will output a file in Xfig format. Then you can draft on the figure. If you don't already have Xfig (it comes with most Linux distributions), then download it from, https://sourceforge.net/projects/mcj.
