I'am building a smal sail boat made of plywood-epoxi construction. I am trying to model the boat in proe, but I am finding a lot of troubles. For instance I model the sections with curves (2D poligonal curves), and then I create 3D splines using the corresponding points in the sections (the vertexes of the poligonal lines that made the sections). After that I use this 3D splites to create a sheetmetal part using two curves, and then I change the attributes for making this metal part developable (excuse me but I use PROE in spanish and I do not know the exact translations of the commands). This part has a lot of troubles that I think that can be solved if I could touch the parameters of the 3D spline (the tension), but I do not find the way to do it. Somebody has tried anything similar ??
Thanks in advance,
