I was trying to model the tail fin(vertical Stabilizer) for an aeromodel design. I inherited a dwg file of the tailfin with some poorly defined ribs that help shape the fin. The fin tapers back and up.
My problem - I need to put in a brace which starts from the front of the lowest rib and goes back and up to the front of the topmost rib. and a pair of slots similar to the ones already modelled but further up towards the front. I hoped that a sweep feature on the assembly would do it but i am unable to create a rail and constrain it properly. Could someone please show me or tell me how these types of features could be modelled?
Another issue i had was to model a plastic film covering for the fin. An aeromodel uses a heatshrink monokote film. How would i model something like that in inventor.
