Thanks so much for the info on the unfold tool. This is exactly what I need to convert the 3d curve to a 2d shape that I can have manufactured. I have my first customer for my wind turbine design but the blade design has been a hangup as my manufacturer was unable to determine the curves to cut for the blades. Not knowing CAD, I was at a loss. I can't put into words how great it is to have a solution. Thanks a million!

Ok, I must be doing something wrong. I am building a model wind turbine and want to cut out blades for the model. The blades wrap around a frame in a helical design. I want to flatten the helical shape so that I can get the 2d curve that best approximates the shape of the blade. So I download both plugins and select a plane and select my model. I run the flatten plugin and I now have a blue box around my model blade, but it is still in 3 dimensions. Any ideas as to what I am doing incorrectly? This looks like a great plugin and is just what I need to get my new business started if I can make it work! Thanks in advance for your help.
