I have 3D models for humans in
inventor. I can get them to you. I am out of the office this week,
but when I get back.

I would love to get a hold of some human
models. Joe uses RHINO, I have inventor 11 pro. I can convert a IGES or STEP
to a file Joe can open.

James,
Ugly as a dogs
butt perhaps, but my dog Harley likes it. ; )' That hull was just for
fun. You win some and loose the rest. In regards to a human model, I
need to do the same thing. Carsten some time back, posted some human profiles
on the Moki picture exchange I was planning to use as a base to model mine in
Solidworks. Obviously Joe has a human model, but so far we have not figured
out how to exchange IGES or STEP files that work. Perhaps we should try again
Joe. Will your CAD program Inventor except IGES or STEP files. STL
files should also work, but they don't give you as smooth of models as IGES or
STEP files. I think you said you have Solidworks, so why would you want to use
Inventor? I'll be interesting in seeing your model of the swing able half
ladder.

Brent

Brent,
Yep...that is the basic idea....but I hate the lines of your sub. It's
about as ugly as a dogs butt. (Sorry.....couldn't resist) I'm a more formal
lines type of person. Not to say new shapes and ideas are not viable or
possible, I just like the way the tubular shape of a sub looks.
I've
been working on the design some, but haven't had a chance to put anything on
the web (mainly because I'm not finished yet).
I know what I could really
use....a model of a person for inventor. I need the representation (movable)
to make sure the sub scales out to the right size.
With the Stepped
sail design.....it is important to know the average shoulder width.......so
the person in the top dome can actually move.
I did decide the pilot
(captain, driver, etc.) will be located in the lower dome......it would be far
to hard to position instrument and controls in the top dome.
Also I'm working
on a boarding idea for the upper dome......like a swingable half ladder. when
pressure is put on it.....it locks in position, then the ladder has spring
indents for other positions when no pressure is on it.
I'm actually
trying to incorporate all the necessary piping and bulkheads ( and such) as I
go. I do not have an extensive library......so some of the items will be just
blocks.

Greetings James,
It can and has been done. I would
add some thickness to the flange at the angle joint. Here is the model I just
finished of a stepped sail basicly like the one you showed use. I was just
going to build the sail 3D model, but I got carried away.
