 Cliff,Which software is most easily learned? I have no CAD experience. All my design work in the past was all sketched out on a bar napkin. Haha.Thank you,Scott Waters

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!

I am wanting to show the components of the submarine how the sub originally was and then how we are changing it. I am not trained in CAD and was wondering if there is someone out there that could easily do this?
