Hi guys,

I have a problem with the node “CoordinateSystem.ByOriginVectors”.  
Im trying to create a coordinate system on every point which is on my curve.  
The direction “x” should be in the curve direction. And it is, but not always in the same direction. Sometimes to curve end, and sometimes to curve start.  
Any idea?  
Thanks in advance! 🙂

Hi, I have also noticed this some time ago, i think i just created new coordinate system, just reversing axis vectors in positive direction. But I used it just once, and havent check it, if it works in every situation.

I hope this helps 🙂 .

Hi, coordinate systems may lead to problem when you work on wrong working range(i.e. you have 10k points but vectors are too small). Try to work on different range or scale your geometry

Hi Jan,  
thanks for writing me.  
But what I should do exactly with that?  
Because Im using the curve parameters to create the coordinate system.

Hi,  
thanks for writing me.  
I have tried to use a different range or scale but it still doesnt work 100% correct. 😕

Got it work. Solved it that way:
