hi guys
dan is right about keeping
it simple, for under a hundered and fifty bucks you can do a nice setup and
what's wrong with using the kitchen table with a portable board.
i use a cad program because i
can give it the machinest and he enters it into the machining center, with
out having to redraw it. it is much cheaper that way. that is also why most of
my drawings are not dimensioned.
That said, cad programs can be a
bitch to run and they normally have shit for documentation, the online
help will drive you nuts and you can spend hours or days trying to work with a
simple solid if you have the wrong option selected. taking a class at your local
community college can be the cheapest and in the long run best option, where
else can you get face to face support.
all of the good programs will
allow you to work with solids and automaticly generate all four normal views and
render them. but most of the time you only need one or two views for the
project. Are you trying to sell a set of plans that everyone will use, or are
you going to build a sub. simple one sheet written directions can be as good as
any drawing. IE. " install first support ring at station 4 and space the
remaining rings on twelve inch centers after that". took five seconds to write
would take one hour to draw.
for system design software a
copy of visio would be the best of the cheap. It has a good data base and not
bad documentation. it will handle all plumbing and electrical design with a
built in library of valves, fittings, tanks, ect.
one note on system design. hyd
fuses should be used on all pressure tanks carried internally.and all hull
pentrations that are normally open, if you rupture a o2 line and drain the
tank it can bring the o2 level to a toxic level. and don't get cheap on the
fittings. I only use stainless steel swage lok, they can be had for cheap on
ebay.
sorry for getting long winded, as with any advice
take it with a grain of salt.

Shawn you obviously know your software, but both you and Dan both make a
great case for simplicity. Alibre really looks good but I see what you meant
when I saw the tutorials.
The laptop is just much more convenient than drafting supplies but I can't
seem to get accurate enough scale with paint and word so I think
something like Smartdraw is the better choice for now.
Already did a paper model Brian but the dog ate it.
Thanks
Joe

dont forget a compass... screwed
without one really. :)
Ya know, people think manually drafting is
cheap. It's NOT surprisingly enough. I found this out a few weeks
ago. You can spend hundreds of dollars before you even draw anything,
and this DOESNT include a drafting table. A good drafting table will
cost $400+. There is a new one out called the Alvin Creative
Center though. It's about $175 and well worth it I think (comes with
light, table, chair, base, containers, etc). But, you still have to
buy a large T-bar in order to get squared, they're like 30
bucks.
My opinion is, if you just want to jot down
scaled ideas then dont bother with serious drafting equipment and/or
software. Just use programs like SmartDraw, Visio, even Powerpoint, or
just stick with Paint and Word. Dont forget all the freeware out there
too for 2D and 3D. Biggest issue is learning the stuff.

Joe,
T-square, 30-60-90 triangle, 45-45-90
triangle, scale, pencil and paper.
All for about ten dollars, if your
up on the technology. ;-)
Sorry, I just had to, Dan H.

The time has come to graduate from MS Paint and Word as my primary
design software.
Any suggestions? Try not to bankrupt me though! :)
Thanks
