I suspect that if you create an identical match, it would be
claimed to have no soul.
Thank you Chris.
I joined Orchid to learn things I don’t know. And in the spirit of
community, I wanted to share the little I do know. I am disheartened
that this group would allow members to speak authoritatively on
subjects they obviously know nothing about. It seems that Orchid is
not a place where technology can be discussed.
The incoherence of “CAD can’t”, to it can with “$10 mil of computer
equipment and tools”, to faulty understandings of Moore’s law and
"consumer operated CAD" is astounding. This is a whirlwind of
confusion, not communication.
I know CAD folks who are already complaining that their work is
being outsourced to cheaper firms out of the country."
Jo, this is happening. You can pay $60 or $600 for a model. For $60,
you get someone who’s never cast or set a stone or even held a
As this field matures, these guys will disappear and the prices will
reach an equilibrium. The same thing happened to the software
industry in the mid-2000s.
It could slice a hair into 14 cross sections length ways.
Richard, that’s physically impossible. A human hair is at most 180
microns thick. When you cut something, you have to subtract the width
of the cutting tool. The smallest mechanical cutters are in the 50
The smallest focused laser beam is in the 25 micron range. 14 x 25 =
The top of the line micro cutting machines, the ones used in nano
tech and micro fluidic research laboratories cost about $25k. I just

Moore's Law still in effect, CAD interface shall become friendlier
and friendlier and learning curve shorter and flatter"
Leonid, you somehow manage to share the exact opposite of fact.
Moore’s law says that every 18 months, manufacturing advances cut the
size of a transistor in half. But this law has a limit which we are
approaching–the size of an atom.
Electronic devices either become smaller or more powerful. Increased
computing power lets you do more complex things. Increased
complexity increases the learning curve.
Ease of use is based on the craftsmanship of the software developer
and has zero relationship to the power of the hardware. CAD has been
around for 30 years. In that time, we’ve seen huge advancement, but
the people who say it is getting easier are selling smoke and
Of course a finished piece can be scanned/moulded and replicated
There are things that can’t be done in CAD. But anything that can
be cast can be done in CAD.
What can’t? Well I would never CAD a tiffany head. I guarantee my
work and a casting wouldn’t be as strong as a hammer forged peg head.
I can do any pattern in CAD, but no amount of ‘terabytes of RAM’ will
allow a software program to use a torch to perform reticulation.
