Making yacht drawings in CAD

[bill424]

I'd eventually like to have a 3D model of the boat I'm trying to buy. Initially, just hull and bulkheads, but eventually deck, rig and other things in the boat that take up space.

The hull shape seems hardest of my initial requirements. Any thoughts on 3D software that can make a decent model of a boat from stem to stern? So far, OpenSCAD is what I'm playing with as I found a hull builder program for it.

You could try FreeCAD or Rhino (student). Is this just a model for viewing or are you doing design, flow calcs etc.

Just viewing. Since I posted, I've been trying OpenSCAD. Too little experience with it so far to tell it it's what I need, though I like the concept.

I used deltacad for 2d. $45 I think I bought when it was 20 20 years ago. It's very easy to learn

Progecad for 3D $250. I just. Bought it I plan to do 3d of the boat some day. I posted drawings of my gin pole winch. Platform drawn with it. It works like AutoCAD which is a plus.

Good luck tom Bodine

I would be curious to see your OpenSCAD results and hear about the hull generator script.

Go to https://www.boatdesign.net/forums/design-software/ and look for threads by pafurijaz, who demonstrates many kinds of software that can be used for boat modeling.

Here is one that has a hull from Free!ship exported via IGES into Rhino3D and was trimmed to match intended sheer and transom. The hull work takes minutes, the deck and such has taken hours and I am still a fair ways off. I am a newer Rhino user. The keel was already in Fusion from another project and easy to import back into Rhino.

Thanks for the link Bill.
I ran the file as-is, option 2, through OpenSCAD and got this:

You can 3D scan your boat & make a point cloud file which can then be cleaned up & manipulated as you like. Hull & deck. Iphone 15 has lidar, making it pretty accurate. Dot3D and Modelar in the Apple ecosystem are available. No clue on Android.
