      I have a set of drawings for a dinghy, but I want to place this within DelftShip so that I can then look at the current characteristics, and to then make some modifications to the design. I have been taking measurements of the drawings and place them as points within the software, but in some instances the software then attempts to remodel the hull form missing out control points and missing items out changing the shape. This is for a dinghy and the design has been built around easy to build which marine ply, but the resultant models end up with complex curves (relative to flat panels). How can I prevent the software for reshaping the model I am attempting to produce?

      Hi Graham,

      If your dinghy is built from flat panels, set the horizontal edges to ‘Crease edges’. (select the edges so they are highlighted, then click ‘Crease’ in he Edge menu, on the Home tab)  This forces the surfaces to follow the edges more closely.

      Hi Maarten,

      I have the same problem as Graham above but the hull shape I am trying to replicate is not based on flat panels and so I cannot set crease lines.

      Is there a way to force the modeling to follow the control points?

      Thanks,

      Hi Fernando,

      Because of the way DELFTship currently works with a control net there is no way to force a smooth surface through control points. We use background images (lines plans) to manipulate the control points so the surface matched the design

      Thanks, Maarten. That is what I have done. It can be done but it is painstaking work.
