Thanks for reading my post. I am trying to model a compressor stator blade by importing an airfoil profile on two different planes. I twisted the upper airfoil profile by around 42 degrees but I maintained the center of the leading edge curve for both profiles on straight line. I have made a guide curve using 3D sketch to connect both airfoils trailing edge but when I lofted I got this error"cannot knit sheets together". I am not sure what is the problem. The strange thing is that I have created the same geometry with different airfoil size and without guide curve and they were all ok and looking good. Please share with me your ideas of what could be the problem. I attached an image of the error and my solidworks part file.
