    I am a Marine Surveyor/Designer looking to pick up some extra work doing drafting and small MCAD work. I can work in almost any software you may need but I prefer Solidworks and Rhino 3D. I can also provide Rapid Proto Type parts of anything from a half/full model to simple shapes for castings. I will also digitize existing drawings into any CAD format you require. I have a degree in Mechanical Engineering and have been a hands on boat builder for 28 years. If you are a designer, boat builder or just someone who needs some CAD work please contact me.

    Thanks

    Can you work off a standard table of offsets?

    Yes I can, but as a senior member I’m sure you are aware of the problems of converting hand faired lines to digital. I have had success in doing this through MultiSurf then converting to NURBS but care and time must be taken to ensure accuracy. I did this with a 46 Convertible were the main designer was old school and did everything by hand but the builder only wanted to work with CAD files, the results proved to be more accurate than the builder could reproduce on the shop floor as all errors were found to be in the full scale lofting. Do you have a specific need in mind?

    I don't have anything specific, but like to keep my options open. I prefer to design by hand and loft the lines. However, if there is an economic way to convert them to do displacement and other calculations in the computer, I could hve the best of both worlds.

    I still like to start my lines by hand till I get the “look” right but move to CAD for fairing and Hydro. If you want the best of both I recommend moving the lines to CAD as soon as possible that way you’re not trying to make an exact fit. As for economical if you take this approach it’s only a matter of an hour or so to have a hull in CAD but of course you then need to spend more time tuning and tweaking till your happy with the numbers and looks. I did just get a good deal on a digitizer on Ebay so one of the first things I’m going to try after getting it working is to see what I can do with an old set of lines I did by hand years ago. I’ll let you know how this works out?

    I never heard of using a digitizer with lines. Does it recongnize them like a scanner does with text?
