thanks alot Anthony. This is great. the points dont move!, however between
the first two points on the curve, the parameter 'u[]' value goes from 0 to
1 (which is great), but then the spaces along the curve after that start
getting longer. so between edit points 2 and 3 on the curve is u[1] to
u[2.4] roughly and then edit points 3 to 4 ranges from u[2.4] to u[4.6].
I'm gonna test a few things out. Thankyou for your help,
Sam
