Hello, I am trying to mark the points normal to the 3D polyline using vector. but as seen in the image, for a small patch the vector changes to opposite direction. any leads or solution on how I can identify and reverse (vector.reverse node does help) the direction of those vectors and create the updated list.
Hi @SkUbaid you could try “normal at parameter” or the new one with side 
…if the old one i like to calculate the vector cross, between normal and tangent

Thank you @sovitek, it works perfect. Have been scratching my head all day for this

since I am using 2023 version the first option works for me.

@RMohareb, I will definitely try with the node from the package and will get back to you if I face any issues or challenges. the node does seems promising.
And for the document file and link I have my weekend sorted with that.
