Turbocad 6.5  It is the easiest to use of any of the cad tools I have come
into contact with.  If you want to use an arcane Autolisp then it has that
as well however in 2.5 years of designing my aircraft in complete 3D the
only time I have had to use a scripting language was when I wrote the code
to draw NACA 4 and 5 digit airfoils and for that I used Basic.
It can be extended using C++ (the language I use professionally) but I have
not found the need.
The aircraft I have designed has around 300 drawings all rendered in 3D and
then projected onto drawings.
You can download a trial of 6.5 at http://www.turbocad.com and I can fully
recommend it.
