1. Sequence((x(A) + (i * l / d1), y(A)), i, 0, d1) → top1
2. Sequence((x(A) + (i * l / d1), y(A) - yb), i, 0, d1) → bot1
3. Sequence(Segment[Element[bot1, j], Element[top1, j]], j, 1, d1 + 1) → seg1
4. Segment(C, D) → a
5. Sequence((x(A) + (i * l / d2), y(A) + yb), i, 0, d2) → top2
6. Sequence((x(A) + (i * l / d2), y(A)), i, 0, d2) → bot2
7. Sequence(Segment[Element[bot2, j], Element[top2, j]], j, 1, d2 + 1) → seg2
8. Segment(E, F) → b
9. Segment(G, H) → c
10. Element(bot1, n1 + 1) → S
11. Element(top2, n2 + 1) → Q
12. Vector(R, Q) → u
13. Vector(T, S) → v
