I'm thinking of having someone else do my prototypes for me in
the future. My skill level is beginner and my design sense is
What sort of look does your advanced design sense favor? Is it
something you’ll be able to adequately convey to another person? One
of the nice things about designing on a computer is the fluidity of
the model while it’s in progress. If you don’t know exactly what
you’re looking for, but figure you’ll know it when you see it, then
you might be better off doing the designing yourself, tweaking the
model until it’s right. If you do this to a person who is trying to
carve waxes to your specifications, it might drive your carver
My question is what is cad cam capable of producing?
CAD, generically considered, is not really limited by anything
particular in what it can produce. Your imagination, skills, and
aesthetic sense are the main boundaries. Of course different
specific programs are strong in different areas; the one you choose
may determine how things come out, to a certain degree. CAM (which
generally means subtractive carving using a rotary spindle on a
computer-controlled tool) on the other hand, has some definite
limitations, mostly related to the ability of the tool to reach the
surfaces of the part, the necessity of holding onto the part while
cutting, and the ability of a round tool to produce sharp interior
corners. However, additive Rapid Prototyping machines won’t suffer
from these limitations, since they don’t use a cutting tool.
Where does one look to find someone who does this?
This might be a good place.
And comparing a traditional hand wrought prototype model and a cad
cam model, which is better and why?
[I don’t think something is necessarily better by being
“hand-wrought” (let’s not get back into that debate, though). I do
feel that some designs are easier to do by hand, and others are best
done (or only possible) using computer-aided techniques. Whichever
method best realizes the intent of the designer is best in my book.]
What is the typical cost of having someone else do your modeling?
That depends on the complexity of the design, how exacting you are
about its perfection, and who you use…
