Placing Family

[yaseminV2XL5]

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

[sovitek]

i dont have any family but something here maybe

[yaseminV2XL5]

Hi @sovitek. it’s not working on me. Where am i going wrong ?

[sovitek]

Hi try join your curves

[yaseminV2XL5]

It doesn’t work either.

[sovitek]

have you joined the curves ? can you share a rvt with that family

[yaseminV2XL5]

there are not polycurve. There are curve. I try it to share. Thanks

[sovitek]

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

[yaseminV2XL5]

You are right. if it is Polycurve, your lines work. But my Curves dont work still.

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.
