        Not exactly, but both provide both a point-n-click and command line tool
selection. (Not exactly because while they provide 90% of the same drawing
element capabilities, they do have difference is how objects are made like
'arcs'. There isn't a one-to-one for each of the 'radius-angle' or 'three-point'
if I recall correctly.

        The logic in QCad is likewise very similar to AutoCadLT (which has the 
same
command interface as its big brother). I don't want to say 'exact', because it
has been at least 10 years since I used AutoCad. I do use QCad and it is a true
Cad program.

        The interface will leave many scratching their heads saying WTF, 
because like
any true CAD program it isn't 'page' (sheet of paper) based, but instead works
(or should be worked with) in 'true size' where the drawing environment is set
by the user to be in actual size (whether in Angstrom or Astrological Units).
For printed output a simple scale factor is applied to produce a drawing on any
size paper. (all of your packages print this way, but in many Cad programs,
given the varying size and diversity of possible units, this is normally left to
the user)

        Both AutoCad and QCad provide support for Lisp programming language for 
object
definition, automation, whatever you want to script related to drawing objects.

        Why are you asking?
