Creo is still relatively new to me. I am trying to model a curved rasp-like surface with rows of staggered teeth. However, I cannot figure out how to reasonably create the teeth profile. In Creo I have gotten up through the stage shown in Figure 1. Figure 2 shows what I am trying to make (modeled in a different CAD program). Attached is a parasolid file showing the geometry. My first thought was to extrude a cut from the side to create the profile, but doing so would take a chunk out of the next row of teeth. Any suggestions on a modeling strategy?
