I currently have C3D 2009 and work in a civil engineering firm however I own a sailboat and am looking to do some redesign. Any idea which Autodesk product I should use? I'm also looking for Marine details, blocks and all that good stuff. Any info would be greatly appreciated!

I can't imagine the torture that would be required to do this design with an AutoCAD based product. I think I would look at Alias and/or Inventor.

Owning one of these things is often torture in itself! We have been doing things old school (you know with pencils!) Then my husband said "what the heck are we doing, don't you have software for this stuff!" I've had absolutely no luck using C3D and have scoured the net and there's not much out there. At least not that people are willing to share.

Have you thought of one of the 30 day trials of some of the Autodesk software? Lots of folks swear by Inventor, but nillaCAD is capable of 3D lofting etc. Will you have a steep learning curve or are you already familiar with CADD drafting practices?

If you search for it you can find on the autodesk website, the special they are currently running (until sometime in January) that bundles AutoCAD LT with Inventor LT. AutoCAD LT by itself will do 3D wireframe and a pseudo 3D that can be shaded, and can display anything created in nillaCAD. It won't draw meshes or solids from scratch, nor does it have full rendering capability. Inventor does add some 3D capability but you'd have to assess your needs and read into what it has to offer. If you have lots of money to throw around you can get the full blown Inventor.

If you are just a hobbyist you might want to consider ProgeCAD Smart, which is not for commercial use but does have the ability to do 3D meshes. ProgeCAD Professional on the other hand will create 3D solids and costs a pittance. Both will handle AutoCAD drawings. The program you have now is for Civil work. Good luck to ye!
I hope my info was useful, but if by some odd chance it actually solved your issue, feel free to mark your post as "Accept as Solution". Thanks! :smileyhappy:

You might use the vanilla commands and go through these to get started

Stick with pencils, unless you are designing a VOR70 or the likes, or will make G-code.

Even with the Lofting functions of recent Autocads, the manual generation of the reference curves and subsequent lofted surfaces and solids is a giant job, and changes cost near infinity.

Which is why boats are designed with dedicated software.

For plain autocad, or Civil, you can use Splines, or arced Polylines to manually fair some reference curves, starting with the body plan. This will provide accurate points for the take-off tables.

A manual method could use Divide, Array and Trim to draw various curve points, for your digital half block model.

I would definitely make all of the drafting by a parametric routine, and the easiest way is by autolisp.

If you do something along the CAD path, post it, or tell me: jevewoods at yahoo.

Go with what is affordabililty and usability. You should start designing by modeling it. Rhino is good for modeling and will convert to CAD for drafting details production.

I thought Rhino is CAD?

Our modeler use RHINO to model for concept and for design layout.
AutoCAD is used for Drawings production.
RHINO converts to AutoCAD. I have not played in RHINO environment to know this -I was told it does not converts to AutoCAD accurately in terms of dimension (ex. AutoCAD come in 2.0015 instead of 2) and intersecting corners is not itersecting on accurate points. So RHINO converted AUtoCAD would have to be reworked to be accurate for production.
As far as creating curved shapes like shell plating RHINO can only create surface not thickness, so AutoCAD would have to do the job.
Question:
What are the steps in creating 3D model curved shape shell plating in AutoCAD?
