Draw an elbow in this drawing?

[CreekWalker]

I can't figure out how to make this elbow in my drawing.

(Image and dwg)

4 hour now and i can't make it.

The last ring is the only one that's in its right place, the others is testing only!

What should i do to make it work?

Hi,

i suggest to use path option from Extrude command.

Command: EXTRUDE
Current wire frame density: ISOLINES=8, Closed profiles creation mode = Solid
Select objects to extrude or [MOde]: 1 found
Select objects to extrude or [MOde]:
Specify height of extrusion or [Direction/Path/Taper angle/Expression]

The easiest way to draw is to layout lines at the appropriate angles (in this case of this 3 gore elbow, 90 / 3 = 30 degrees) recognizing that at each end of the elbow, one of the 30 degree segments is cut in half (15 degrees) to achieve symmetry about the centerpoint of the elbow.  Draw each segment long and then modify using the SLICE command.  Since the elbow is symmetrical, only half needs to be drawn before mirroring.
