Once I’ve created this grid I go to the “record history” (right click on it first to make sure the “update children” is ticked) and left click to turn on, then go to the “loft” command. If you select one of these line in the non surfaced model then turn on the “edit control points” you will see I only used between 2 or 4 points for any section. The object is to get a continuous line from keel to shear (blue lines in file). For this I use “control point curve” for curved lines, with the minimum number of points to get the basic shape I want or a “polyline” for straight sections or a mix of both. I start with a keel line to temporally anchor my bow shape, mid section(s) and the stern. Likewise for the lower surfaces.īen B another way of getting to a simple hull shape like your dinghy shape that is editable, is what I call control sections. The forward upper and aft upper surfaces can be merged after matching if desired. You may need to go through the 'MatchSrf' steps a second time to ensure everything matches properly. Use 'MatchSrf' to match POSITION (not cuvature) of the lower edge of the upper aft surface and the upper edge of the lower aft surface. Use 'MatchSrf' to match curvature of the forward edge of the lower aft surface (select first) to the aft edge of the lower forward surface (select second). Use 'MatchSrf' to match curvature of the forward edge of the upper aft surface (select first) to the aft edge of the upper forward surface (select second). Use 'MatchSrf' to match curvature of the adjoining edges of the upper forward and lower forward surfaces. Also the adjacent corners of the surfaces need to match in position. Adjoining surface edges need to match in position. The split between the forward and aft surfaces corresponds to where you want the chine to completely vanish. Start with four surfaces per side of hull: upper forward, upper aft, lower forward, lower aft.
