[PSUBS-MAILIST] CAD for presentation

Fri May 27 09:52:31 EDT 2016

Scott, I have been thinking about your request for CAD assistance for
upcoming presentation.  I think with your Pisces VI build, you really have
both tactical and strategic technical drawing needs.  Let look at the long
range strategic need first.  Because you are going to make some changes to
the boat, ABS is going to make you submit a report that among other things
has a drawings set that reflects the current build, a weights and balance
and buoyant accounting that rolls up the new CG and CB of the boat and a
stress analysis of the pressure hull both in the form of the ABS hull
stress calculations and an FEA.    The best way to get these is through a
3-D modeling package like Autodesk Inventor Pro or Solidworks.  My
suggestion is to invest in one of the software packages and take a basic
3-D modeling training course on the software.  You then crawl into the
belly of the beast with your tape measure and digital caliper and take the
dimensions of each part and then model it in the 3-D modeling software.
After you get all the parts modeled, you them make up assemblies of these
parts that will enable you to turn out the 2-D prints of the parts and
assemblies.   From this 3-D model, of your Pisces VI, you then can extract
the CB, CG of the boat.  All of these 3-D software packages let you export
STEP files of the model that can be read by the FEA software Sean uses.  If
you pay some one to build this 3-D model, first of all it will cost a lot
of money and every time you change anything you will have to go back the
guy for an update.  In the long run, having this skill set (3-D modeling)
will be very useful for future mechanical projects off all types.

>From a tactical perspective, what people are most interested in, from my
perspective, on your renovation is what is the state of the boat at the
time you acquired it documented by lots of pictures, and what the big
pictures is on what you think you will need to do to get your ABS
A1 recertification and lastly what are the major structural changes you are
planning.  I don't know how much time you have for your presentation but my
guess is 20 minutes or so.  If this is the case, on average you can count
on about 1 min per slide so you have 20 slides to present.  This does not
leave much time for presenting CAD work.  You might be able to get away
with the basic drawing tools in Power point for these few slides on the
changes.

Make sure you put a slide in for your new mega shop which we are all
salivating over and how you are going to dive this boat when your done in
Kansas!
