UPDATE
you can create some parameters to control this part:
D: diameter of the spiral
DT: diameter of the tube
DC: diameter of the circular section around the tube
NS: numbers of spirals
NC: number of corrugations around the tube
HS: height of the spiral
First curve:
r = (D/2)
theta =...
Dear Fsdani, try in this way:
1-create a curve with a polar coordinate system:
r = 80
theta =4 * t * 360
z = 200 * t
2-create a sweep with this curve (tube)
3-create another curve with a polar coordinate system:
r = 80 + 15 * cos ( 40 * t * 360)
theta =4 * t * 360
z = (200 * t) + 15 * sin...
