I am working on a tutorial for advanced modeling. It's from the staffs uk site. I am trying to do the rib creation psrt and I am confused. Its telling me that because I have a free form surface I need to create a curve for the rib. I think that this tutorial is missing somthing. They are telling me to pick one half of the shelled feature and then the datum that goes thru the feature. Im doing somthing wrong? Here is the link to the tutorial The area in question is advanced modeling page 4 relating to figure 14. Please take a look at this and help me out.
TIA
