In the Footy forum Dick Lemke asked...
"Muzza - do you (or anyone else know) if either program will allow you to develop panels that would be "bent" to shape? I know that hard chine panels can be printed flat, but I am wondering about compound bending?
I am thinking (not to hijack the post) about a compound bent panel of thin ply for a set of multihull hulls. It is done in big boats, but can't find any technical info - and just wondering if anyone using either of these programs has seen anything in the instructions on use?
I built a double-chine IOM to my own design using Hulls. The bends in the chines are in two dimensions and worked OK but not perfectly. I think this had more to do with issues associated with my printing the panels onto A4 sheets and then attempting the sheets of paper to get the full sized panel. As I built the boat by placing the panels over stations it may also have something to do with errors in my stations.
I scaled the plan down to just 12 inches long (Footy sized - but not Footy displacement). This was so that I could print the panels on single sheet paper to see whether the error was mine or the software. I glued the paper panels onto some card, and then made a mock-up hull with the card with tape. This time the panels were a perfect fit, but the hull came out slightly longer than the 12" I had intended. this may have been something to do with scaling issues between the software and the printer.
As you can generate DXF files from Hulls, it is easy to insert a scale. Then you would have an accurate check of the panels once printed.
Here is my double-chine IOM (printed from Hullform). In this case I did the initial design in Hulls, then imported the offsets to Hullform to check various things. I used Hulls to print the panels. You can get an idea of the way the panels curve from this image.
