Previously you have learnt that you can start a project by starting from scratch or by using an existing design and modify this to match design requirements. Generally, the naval architect is confronted with a variety of projects with different combinations of input data and output requirements. For example: a customer only provides paper drawings of a ship and needs to have the stability booklet re-issued after a modification to one of the tanks. This means that a Maxsurf model has to be created so that this can be used in Hydromax for Hydrostatic analysis. Another example may be that the customer has a DXF CAD drawing and wants to build a similar ship with minor modifications to the sheerline. In this case a Maxsurf model has to be setup in such a way that the surface model is useful in Workshop to expand plates, define stiffeners and frames and other primary construction parts. Both examples above have different input data and require very different surface models to deliver output that satisfies quality standards. Deciding the most cost effective way to handle the examples above requires a fair amount of experience and is thus not within the scope of this training manual.
