Attached is a project I am working on but I am having problems creating the outside surface of the airplane. In the model there are several profile curves along the length of the plane and I had been using the sweep 2 rails function to create the surface between each set of profile curves. I also tried lofting it by selecting the profile curves still didnt work as can be seen in the file. I'm sure there is an easy way to fix this but i am still pretty new to modeling like this.
Thanks for any tips to get this straightend out.
