Hi Barry and Michael,

Many thanks for response - I have exploded the curve selection but the curve is one continuous curve I have added the start and ends with a set figure so I know which direction the curve data is given.

Barry with the NodeEditor I think I may be missing something as I cant get it to run - I downloaded the latest from James archive let me know if this is same version you are using.

I have just completed small tube bending exercise (Balloon Girl) as a test run before I embark on this next project which involves 90m of tube.
