Hi all. I'm relatively new to SolidWorks, but I've gotten a pretty good handle on it so far. However, for the life of me, I can't remove the exact amount of material I need for my project. I'm trying to model a dagger blade that has four facets, and the tip is formed by a parabola on the vertical plane and a parabola on the horizontal plane. I've got the entire thing sketched out, butI can't seem to find a tool that will cut along the curve like that. Any help? Picture and design file are attached.
