CAD for those who do not have funds for commercial software

For reference: another option is FreeCAD, a 3D parametric modeler. I barely understand how to use it though. Those are quite complex softwares. I would love to see specific tutorial relate to ship modeling.

a lot of the CAD software is complex, however you do not actually need all the tools and functions.

what are you lwanting to learn from a tutorial on using CAD to draw ship plans?

drawing a plank on frame or plank on bulkhead?

this is a working master drawing in Auto Cad. The white squares are scans of the original drawings that are being traced.

from the original plan i create 3 views an inside profile an outside profile and a framing plan. As i develope the drawing more and more details are added.

FreeCAD has greatly improved in the 1.0 and more recent releases. When Fusion360 started playing silly games with licensing I bought Alibre Atom as I wanted parametric cad / 3D modeling and the maker version of Solidworks was in it's infancy and lacking too many features . Over the last few years, the Maker version of Solidworks has gotten MUCH better and now has CAM included. It does have some restrictions if you need to co-exist with other CAD programs, just a heads up. You'll be doing the IGES and STEP shuffle, or maybe using OBJ or STL files to play nicely with others. Flip side is that right now the annual subscription is half the cost of annual maintenance on Alibre. FreeCAD still has some quirks, constraints are sometimes oddly behaved. For $24 USD on a special this month going with Solidworks for Makers would be my recommendation. It's not free, but it's pretty darn low cost. The install on your local machine is subscription based BUT it does allow running without an internet connection for up to 30 days once all is set up. If you don't have internet in a shop building you can still take your laptop out to the shop and get things done.

I saw some mention of 2D CAD programs, and LibreCAD is very good, very free, and very open source. Makes a linux bigot like me happy. BUT it's 2D. It's not parametric. If you are going to learn CAD today, particularly if any kind of 3D designs are in the cards, going 2D doesn't make sense. It rules out 3D printing, resin printing, true 3D organic shape routing or milling, and sending files to a service company should you want or need to outsource some aspect of a build.
