(sigh) Yes, but sometimes they make MISTAKES and provide
the RIGHT tools, despite themselves! :>

Yeah, but you wouldn't want to make a purchasing decision
based on what you MIGHT find...

The last time I looked at GEDA it was pretty embarassing.
I'm sure *fun* for hobbyists (at that time) but not for
someone trying to get 6 layers boards with fine line rules
built economically (I have very little desire to try to
explain to a board house why the photoplotter output
has a particular bug in it, etc.: "GEDA? Who makes it??")
And, for things like injection molding, even good 3D CAD
programs need "enhancement" to deal with the issues that
are specific to creating tooling that will yield good
parts without lots of "user expertice" to hand tweek the
design. With decent tools, you can learn *from* the tool
instead of trying to coax the tool to do what you want.
I liken this to some of the etch-a-sketch PCB layout tools
that had very little knowledge built in and just acted as
a means for you to "draw" a photoplot electronically...
