Anybody 3D Modeled their boat?

I dunno where to even put this in the forum, but has anybody played around with computer modeling their boat with a 3d laser scanner?

It seems like, with an appropriate aircraft hanger I might be able to make a 3d model of my boat for a few hundred $$

Build a 3D Scanner From A $25 Laser Level - Systm

Re: Anybody 3D Modeled their boat?

I have....sorta. I have a 12:1 3D rendering of my boat on the CAD/CAM program I use in the CNC shop. This way I can see it, and know if it will fit where I want it befor I build it.

Re: Anybody 3D Modeled their boat?

Yeah, I was thinking the opposite I want to be able to make design changes and be able to make plans from what's already there.

In reality I'm just fascinated by the nerd factor of it I think.

Re: Anybody 3D Modeled their boat?

I have one in Solidworks that I didn't bother putting a whole lot of time into. I did it more to see what it would take. The model is based off of a lines drawing that I found.

There are many different programs that you can do this with, I know a lot of people like Rhino for this sort of things and there are a few other popular programs as well.

Re: Anybody 3D Modeled their boat?

I managed to get a set of bulkhead offsets from the designer of my boat and was able to plug these into Rhino for a very accurate rendering of the hulls and decks. You may be able to do the same if you have access to the bulkhead measurements.

Re: Anybody 3D Modeled their boat?

I have NO measurements or plans. I need to use a Laser scanner like in the links so I'm interested in knowing if anyone has built their own or had it done on a large object like a sailboat.

Re: Anybody 3D Modeled their boat?

another way to see it.
thinking out loud....
hull, deck and interior
hull
with the boat on the hard it could be an easy days work to measure offsets.
locate stations on the ground and with a vertical offset references take measurements. (a level is your friend)
deck
...same station points with horizontal references.
as long as measurements satisfy the requirements for a half model, you are there.

produce the drawings and model it as a mesh. (i think)

interior
mostly simple geometry...measure and draw.

most old acad programs should be able to handle it.
really don't see a reason for laser scanning, although that would be very cool.

then slice it. seems like the most informative section would be longitudinal.
once sliced into two halves (port and starboard), views can be rotated any which way.

then send it to a printing house with a 3d printer for a physical model.

Re: Anybody 3D Modeled their boat?

I'm using Wire frames and putting skins on it. This way I can remove , for example, the hull plates and look at the V Birth with just a click of the mouse. Or I can turn off all but the deck and measure something. Then I can rotate it on the X, Y, Or Z axis this helps to.........well, there is no useful reason for doing this, but its cool

Yeah, but how did you digitize it?

Re: Anybody 3D Modeled their boat?

I was thinking about doing my boat. I once did a little 3 tonner named Wild Duck in Redpath Cad Cam software but that was 20 years ago. I have Autocad 12 now but haven't learned how to use it yet.

Check out the links in my first post. I think if you could back the boat into the corner of a hanger/barn/shop it could be done fairly simply.

Re: Anybody 3D Modeled their boat?

There is a very cool little program ....free....that let's you get 3d mesh out of a number of photographs. Of course it won't give you a lot do details but it is fun to play with.
Do a search for 123dcatch
