Hello. How can I place a family along a polycurve in Dynamo, ensuring that each instance is oriented outward and aligned at a parallel angle to the curve? Thanks
Hi @yaseminV2XL5 try normal at parameter, so you can get the right vector on the curved curves
Hi try join your curves
have you joined the curves ? can you share a rvt with that family
there are not polycurve. There are curve. I try it to share. Thanks
yeah but the issue is your curves dont have same direction i guess, so join them first and try an explode, but you are welcome to share for a test
Yours are all consistently oriented inwards, which indicates they curve is going ‘backwards’ (in as much as a closed loop can go the wrong way) relative to your needs. Try adding a Curve.Reverse before you generate the coordinate systems.
yeah all what Jacob say 
) thats the issue, here is another dirty way there probably could work as well…just a fast one…can be made much more elegant…but dont have time, and i just play around

Hi @sovitek . It’s not as dirty as yours, but it’s still a different kind of dirty road.
Thank you @sovitek and @jacob.small . You really helped me solve the problem.
