The aspect of constructing a boat which seems to be most terrifying to the amateur builder (and sometimes the professional builder tooling up for grp volume production) is the lofting of the lines.. I'm looking to create a lines drawing for a ship. i chose a deck area, lbp, beam, depth, draft, and calculated the area for 10 sections, waterplane areas, prismatic coefficient, and other coefficients.. © sailsetc ltd. all rights reserved. 2018. credits & copyright.
In the end, the boat is a three-dimensional object and the lines represent the three-dimensional lines projected onto an orthographic surface. the order is not important, since each of the lines define the shape of the hull.. Lofting is a drafting technique (sometimes using mathematical tables) whereby curved lines are generated, to be used in plans for streamlined objects such as aircraft and boats. the lines may be drawn on wood and the wood then cut for advanced woodworking .. Because the plan view is a different perspective, it stands to reason that we will be lofting different lines or in some cases, the same lines from a different perspective. consider the sheer line. the sheer line is viewed in all three perspectives, the plan view, profile view and the form view..
