I am working on a model of a high speed train and I am having a problem with the nose profile. I have drawn out a bunch of progressively smaller cross sections that lay out the general shape, but I don't know how to convert them from sketches to a solid form. I have used the patch and stitch commands before on other projects, but they are not working very well for this. I tried using the sketches as guide rails, but there would always be an error or 'create feature failed' before I could get them all selected. Should I be trying some kind of loft? Everything I try gives some kind of error message. Is it a problem with one of the sketches? I have included a screenshot of where I'm at right now in the process, as well as the file itself. Beware, this is an amateur job, so it is probably not up to 'professional standards'.
