Describe the bug

When using a canted fin, the fin should rotate around the center of its root. However, in the 3D view, the fin rotates around the aft root point.

To Reproduce

1. Open a new design
2. Add a body tube
3. Switch view mode to top view
4. Add a trapezoidal fin set, set fin count to 0 and sweep angle to 0 (for clarity)
5. Move the cant angle slider back and forth, you'll see that the fin rotates around the center
6. Switch to the 3D view
7. Again, move the cant angle slider, you'll see that the fin rotates around the aft root point
