sliding protusion in space

[cccicccio]

probably what I ask you is simple and banal but it is a day I try without any result.

in a few words I have to draw a 40mm diameter pipe that flows along a trajectory that does not lie in a plane but in space, a propeller type but not regular. Something like a handrail of a staircase.

I think you should use the sliding protusion. How do I draw the trajectory to follow the circular section?

Thank you in advance for your help.

I would say it depends on how complex the trajectory is. you can use the table curve command, or build it by means of intersections of surfaces. until st5 there is no command for a three-dimensional curve, I'm not sure but maybe in st7 you

it is also possible to use the “derived curve” command, selecting as a guide curve for the protrusion the edges of a properly shaped solid (for the sliding protrusion it is possible to directly use the edge of the solid, without passing by “derived curve”).
with the design/construction body controls then “expect” the building body.
for versions prior to st5, which do not provide the multibody, it is possible to realize the protrusion and then eliminate the faces no longer necessary.

the curve for points is from many versions, it is located next to the curve for table.
in the st7 there is the 3d sketch environment which greatly simplifies the creation of complex paths.
