excellent! thank you very much. I had no idea you could do this. Ill take a look at your file later.

Edit - Just tried it and it works a treat, So why does a rebuild make it one continues edge rather than separate pieces (just out of interest)

Rebuild inserts more control points along the curve. Draw a curve then select show points, Now run rebuild on the curve by pressing TAB and typing Rebuild, watch the difference, it's instant!
