If you look in the installation directory and find XFOIL.EXE you'll know its still true. If airfoil designs is all you need Profili for, you can download XFOIL from here: http://web.mit.edu/drela/Public/web/xfoil/ and compile it as a native Linux application. Its open source, released under the GPL and compiles with the GNU f77 FORTRAN compiler - this is just a preprocessor and set of extra libraries for the GNU C compiler and will be a separate package for most distros. There is a binary OS X version of XFOIL linked from the same page. For drawing up plans there are a number of CAD packages available for Linux. I'm still using TrueCAD on an ancient W95 box, so can't talk about them except to add that any self-respecting CAD package should export and import DXF format drawing exchange files and, failing that, most can also handle HPGL files. DXF transfers preserve layering and scale. HPGL doesn't, but with some work you can put that back. Martin
