3D Pipes

[danieldalio]

Good night,
I am trying to draw some pipes in 3D.
What I want to is to create a path, let's say from 0,0,0 going 10 feet up, then 15 feet to the left, then 8 feet forward, then 3 feet down and so on.
I want smooth corners, not 90 degrees.
It is my understanding that I can't make a 3D polyline with arcs on it.
I'd like to make my piping by extruding a surface along a path.
Is it any way to make my piping other than creating segments and elbows and joining everything?
Thanks in advance.

I never had trouble making 3D polylines - use 3dpoly command!!

Thank you for the suggestion.

I have not used 3D polylines much so can't comment about the ablity to draw arcs (if any) but what I would do is draw a 2D polyline with a radius at the corner where you want the elbow and then extrude a circle of the correct diameter following the "path" of the polyline.
When you extrude the circle it will follow a path along the polyline relative to the current UCS. Depending upon the number of changes of direction you may have to do this a couple of times after rotating the UCS.

It may not be the fastest way but it has served me well over the years.
