[Rhodes22-list] The best little drafting program and it's free!

[E.Andler]

Chris & Mike:
I forwarded your emails about the free Cad program to my son who is a
Mechanical Engineering student (He has used the Google program before.) 
He also responded on how to mold a 3D hull on a Cad program
I'm going to cut & paste what he said because I have no idea what he is
talking about (I sell empty bottles for a living) If his suggestion
works its nice to know he is actually learning something at school
I would love to see if someone can do it using this method
Keep me informed
Good Luck
Ed A
Here is his response:
	"You can tell them the easiest way to get the boat curves
accurately is to make a few section cuts in 2D (using polylines), align
them in 3D space, and then use the LOFT command in autoCAD so that you
can accurately reflect the fact that both the XY and XZ planes of the
boat are curving simultaneously at different angles (ie the hull curves
both downwards towards the water and backwards from the bow to the
stern)"

Mike:

I have been using AutoCad, AutoCad Architect and more recently Autodesk
Revit for architectural design and drafting in addition to Sketch up for
design illustrations.  AutoCad Architect tried to be a 3D design and
drafting tool but Revit has taken this idea much further.  Revit allows
us
to build a virtual model in 3d and test relationships of various design
elements and  create a set of construction documents and renderings from
the
single model file.  The various components within the model such as
doors,
windows, walls etc... have smart dynamic attributes that can be linked
to
various tables, charts, product web sites, quantity tables, contractor
cost
estimates etc...  

We used to use 3d studio max to create 3d renderings but this was much
too
complicated a program.  Sketchup is a great product.  I think Google has
the
right idea in providing this univeral, easy to use product to a mass
market
for free.  Autodesk robs us every year with a mandatory subscription
that
cost me over $700 per each of my five liscenses.  Sketchup does not
produce
the same level of documentation as Revit however so I am stuck
supporting
Revit.

I would love to see if anyone has success in creating a 3d model of the
Rhodes 22 in sketchup or any other program.  I explored this a bit but
the
complex hull curvature makes it a real challange.  My goal is to map out
electronic and other components in a 3d model of our boats.  Let me know
if
anyone has success in this.  It would be pretty easy to share sketchup
models and collaborate.


Google warehouse is a good place to look for existing models.  Enclosed
is
an imgage from a sailboat model found in the google warehouse.
