Agreed, but would have compared a bicycle and a truck, both are able to
transport goods and people ;-)
But feature modelling, automatic creation of drawings and views,
assembly
modelling, etc. are also possible on cad systems, which cost a few
percent of the price for Catia/Pro/Engineer/Unigraphics, e. g. VariCAD,
which exists also as native Linux version.
Of cource, the quality of these modeller is much more restricted
compared
to the "big ones", but many tasks do not need these capabilities. BTW
VariCAD has a very easy to use BOM mechanism, functions which enhance
the filling of title blocks, etc. which I always missed in CATIA 4 - on
which I'm working for many years.
IMHO I would say, that there are many tools on the cad market, each of
them focussed on a specific group of users and solutions - too less for
Linux :-( and they all could learn from each other.
