Note:
In the images below:
- Seg 1, 2, 3, 4 : Segment of tube
- Length : Length of segment 1
- Point 1, 2, 3, 4 : Constraint point of tube
- Plan 1 : Plane created by point 1, 2, 3
- Plan 2 : Plane created by point 2, 3, 4
- Angle Alfa : Angle between Seg 1 and Seg 2 in the plane 1
- Angle Beta : Angle between plane 1 and Z axis.
Same Plane- Rotation 1 Angle Alfa
- Point Pt 3 moves along a line in direction (Pt 3, Pt 4).
Origin : First Position Pt 3.

- Rotation 1 Angle Beta
- Point Pt 3 moves along a circle.
Center is Pt 2. Radius: Distance between Pt 2 and Pt 3.

- Translation
- Points Pt 2 and Pt 3 move along a line in direction (Pt 1, Pt 2).
Origin: First Position Pt 2 / Pt 3.


Different Plane- Rotation 1 Angle Alfa

Origin: First Position Pt 3.

- Rotation 1 Angle Beta
- Point Pt 3 move along a circle.
Center is Pt 2. Radius : Distance between Pt 2 and Pt 3.

- Translation
- Points Pt 2 and Pt 3 move along a line in direction (Pt 1, Pt 2)
Origin: First Position Pt 2 / Pt 3
