I have already given it. I'll elaborate.
I am making the model of my motor.
I want to make the iron core. That three-winged thingy, a part of the rotor. Since I'm linking everything to master sketch of the rotor, I have to start off this:
Then I add a Lattice array, that defines the number of wings, and is convenient for linking from sketches.
Then I add two sketches. One defines the shape of the wing, the other defines the volume occupied by the rotor.
Now, I Part Extrude one sketch, Part Revolve the other, and Part Common them together.
And populate the array, and fuse it together in Lattice
Done! Now I leave the body, and Part-o-magic automatically switches the body to Tip mode. The final result looks like this:
Here, I hacked into a PartDesign body, to show what I want.
