It is not called a Mould Loft anymore - because they no longer exist.īut it does not mean this function is not done (as it must be) or done automatically by the computer programme. The user must still do exactly what was done before, check to ensure the Lines are fair.
The Maths will produce a nice 'smooth' set of Lines such as:īut it does not mean it ia a production faired 3D hull shape suitable for plate development.
The user must still check the Lines to establish if they are fair - just as the mould loft did before, when taking the Lines from the naval arch. It is assumed by many using computer software programmes that "this fairing" which was done by the mould loft, is done automatically within the programme. The mould loft would take the Lines done by the naval arch - which were a generalised rough guide - and then faired by the mould loft. It is no different to the "old days" when the Lines were drawn by the naval architect and then given to the DO and the Mould Loft. If a surface from a Hull Assistant is used as the input outer hull surface input to create construction math models / drawings then any discrepancies between the outer hull surface and the construction math models / drawings would have occurred during the creation of the construction math models / drawings.Īgain, the Hull Assistants are not intended to match an existing surface or an existing set of lines and offsets.Ĭlick to expand.And here in lies the misnomer about automatic hull creation and Lines Fairing programmes.Įveryone assumes because - the computer is doing it - the Lines must be fair and correct. In my limited experience with Hull Assistants the results appear to exactly match the input data, though as always the results should be checked to make sure errors or discrepancies have not arisen.
Each has it's own set of input dimensions and proportions which the user controls. Orca3D has four different Hull Assistants for (round bilge) sailboats, (V bottom) RIBs, (V bottom) planing power boat, and (V bottom) boats with developable surfaces. They are not intended to replicate an existing design or match an existing set of lines and offsets. The Hull Assistants are intended to create a new outer hull surface based on some basic dimensions and proportions which the user inputs. Perhaps there is some confusion about the intended use, purpose and workings of the Orca3D Hull Assistants.
