How to model Propeller in Solidworks?
Create new plane (plane1), choose right plane as first reference and offset=500mm
Sketch a elips with width=60mm and height=20mm on right plane like picture below (sketch1)
Sketch a point on plane1, and make this coincident with the origin point (sketch2)
Create loft from sketch1 and skect2 (Loft1)
Create flex from loft 1 (Flex1), choose twisting, checklist hard edge, angle=45 degrees, and trim plane1 distance=50mm
Create circle with diameter=130mm on top plane like picture below (sketch3),
Create boss-extrude the sketch3 like picture below (boss-extrude1), choose mid plane direction with depth=40mm
Create cir-pattern loft1 (cir-pattern1), checklist the equal spacing, spacing=360 degrees, and instances=3.
Create dome with depth=40mm like picture below
