Help! i would like to design the blades of an Archimedes wind turbine, but I do not know how to start!
I would consider myself an intermediate, but infrequent user of FreeCAD and I have mainly used it to design rectangular and cylindrical shapes for 3D printing. Now, I would like to use FreeCAD to design the Archimedes blades (see attached image) in a DIY wind harvesting project. I would really appreciated any tips or help to set me off in the right direction.
