The sketching of lines continues with finding intersection points and then sketching fit point splines through those points. Here are the intersection points for the two waterlines, with the waterline planes visible.
Now I’ll create sketches of the various hull curves.
For the topmost line, I will create a curve following one of the bulwark lines on the plan. To ensure correct placement, I create a construction point at the tip of the bow, which will be used as a starting point for the curve. A fit point spline is created in a horizontal plane following the curve as viewed from above.
Step one is to bring the plans into Fusion 360 as canvas objects. The plans are checked to make sure that all lines are perfectly horizontal / vertical, and that lines in one view match up to the corresponding lines in a different view. The images have been scaled in the 3D environment to match the scale of the model (1:64 or 1 foot = 3/16″). The 3D origin is at the intersection of the baseline, the center line, and the forward perpendicular.
My plan, which I hope is not too ambitious, is to make a plank on bulkhead hull. I have access to a local makerspace with a laser cutter, so I intend to laser cut the pieces. I’d like to develop a workflow of going from plans to parts that I can apply to future projects.
Let’s look at the plans of the Sultana.
