Thanks for the quick response !

When i save a home under Mac OS, i can't open it under Windows XP ( error message : can't open home ) ; Is there a way to solve that ?

It really works, I do it very often and all files in the gallery were drawn under Mac OS X. How did you transfer sh3d files from Mac OS X to Windows?

I send it as a mail attachment ( Max OS X at home -> Windows at work )

Also, there is no 'Print to PDF' option under Mac version, is that normal ?

It's useless, since the "Print to PDF" is a standard feature in Mac OS X print dialog box.

OK, i should have tried that before ! it was the goal i wanted to reach, ( sending the plan to a friend that is not 'computer fluent' at all ; so PDF format was the perfect way )

However, i found a work around : Gimp can open .SVG files pretty well and export to whatever format ...

So the problem is solved.
Thanks !
