Designing a boat propeller in OnShape

gilbert_carmichael_gilbert_carmichael_ OS Professional Posts: 4
I want to design a boat propeller using OnShape.  I have a physical 9.25 inch propeller from an outboard to use as a guide for measurements.  I want to start design from the center and move outward.The center of the prop has hub with beveled splines - 10 splines total.   The outside of the splined hub is 20.5 mm, the inside of the hub is 12.5 mm.  The spline height is 1.5 mm and the spline width is 1.5 mm on the tip extending to 2 mm in the valley.  Is there a repeatable way to model the splined hub?  Rotate function?
