Hi guys, We can use $PCT in the Sweep Scale parameter and will get a linear scale from 0-1 along the backbone. That is great and fast! But, why using 1-$PCT does not give us a precise result? As you can see on attached image, both extremes on right sweep are bigger than on left one. It's obvious on the thin end, but also occurs on thicker one… $PCT gives us an 0.0 ... 0.25 ... 0.75 ... 1.0 scale 1-$PCT should give 1.0 ... 0.75 ... 0.25 ... 0.0 scale, right? The same problem occurs when using a ramp: chramp("profile", $PCT, 0) It works perfectly fine at first stage, but if you change your first ramp point control from 0 to 1 and last one from 1 to 0 it clearly appears that the thin extreme is NOT zero size… (?) Maybe I'm misunderstanding something obvious? THANKS for your feedback! NOTE: these alternatives works perfect… $PT*(1/($NPT-1)) 1 - ($PT*(1/($NPT-1))) chramp("profile", $PT / ($NPT - 1), 0) …but it really intrigues me that the more simple $PCT has this problem.
