Turbocad 6.5  It is the easiest to use of any of the cad tools I have

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.

I've had no trouble using Turbocad and I've never used one before and I've
had no problem exporting in DXF for laser cutting etc.
I'm glad someone else has had the same experience. I did look at others
that people gave me, but found them more difficult to use. I didn't know if
it was the cad systems or me, I'm glad someone with more experience has
the same opinion.
