Essentially what I need to do is divide a variable curve; then in each point locate 3 points on both sides spaced 1 mm between them. then extrude those points in a range of .0 to 3 mm. as in the example.
I thought it would be simple but I cannot understand the logic to advance.
additional to this
Can you explain how to group points that are close to each other?
