I am trying to create a mold for the folding propeller, every time I do draft analysis (first step creating the mold), it leaves curved faces as straddle (what to do with them). All the tutorials I have seen, they just click on draft analysis and there are positive and negative surfaces.
I have tried creating a parting line and then parting surface with so many ways but nothing worked out. Now all the efforts seem worthless. If anyone here can guide me with the best possible way to do this, I would be very grateful. Just an instruction/ completed tree diagram to know process/ instructional video or any documentation would be of great help. I've attached the Solidworks(2018) part file here.
