Extra curve!

Hi friends! Can anyone tell me why I have this extra curve at the top? As I want to loft my vase and I can’t! Help :frowning:

Thank you HS_Kim! May I ask why we have to write an expression ‘x-1’?
Couldn’t understand what it means

It simply subtracts 1 from whatever is provided as x-input. In the example above, 8 - 1 = 7! This is necessary, otherwise the Range component outputs an extra value that isn’t needed. You’d have 9 normalized offset values between 0.0 and 1.0 for 8 moved curves, which would produce an extra offset somewhere, probably for the last curve.

Ohhh - I see - that makes sense :slight_smile: thank you so much!!
