I got this soldiworks model from GrabCAD of a boeing 787 model as I dont have enough time to model one. I am trying to create a reference plane from the rear edge of the fuselage as my reference plane at distance of 8000mm into the fuselage. Meaning the reference plane cuts through certain parts of the fuselage and tail section. Doing this gives me a lot of erroes in split lines. I am a solidworks beginner.
I am also attaching a screenshot of the model for your reference.
