hi there,

i am trying to create perp frames on a curve at a series of points. the start of the series is zero, the step is the length of the curve divided by n, the expression is x+1. the last point (n+1, in this case 11) has the parameter t=length of curve (as you can see in the panels). Perp Frames wont accept this and tells me it cant solve because t is outside of the curve. if i substact 0.0001 it works.

i would be very thankful for a solution that doesnt feel like cheating (which substracting a little bit does)
