Hello DS lofting community,
I am an absolute newbie to DS and digital lines lofting (though I have done it a few times by manual drafting).
I have a problem that I don’t know how to control the slope or angle of the tangent of splines at its endpoints.
E.g. I have started with below reconstruction of hull lines of MV Sovereign of the Seas from a tiny General Arrangement Plan (A4 Size) which I loaded as far as stem and stern contours and deck lines were concerned as background images.
As a first draft (still pretty unfair and requires a lot of smoothing) I ended up with attached body plan which superficially doesn’t look too bad.
However, if I zoom in within the waterlines view I don’t know how to make the splines of the bulb intersect CL at a right angle (viz. infinite slope) to produce a nice round bulb.
Also I don’t know what causes the oscillation of the spline of the bulb section at FP (i.e. section 20)?
I rather would give it a shape (smoother of course) of what I scribbled in a green line on the attached pic.
P.S. Oops, where are the sample pics that I attached to this posting?
