Hello guys, I’m new here and would like help if possible I’m trying to create a routine to put posts on curved streets. Initially I managed to extract the curvature of the track and launch the posts at a predetermined distance. Now I would like the posts to be perpendicular to the street. I saw on…

Use ParameterAtPoint to find where your placement Points are along the line. Use NormalAtPoint to find the direction of the curve at that point. Use AngleBetweenAxis (unsure of the Node name here) to find the angle between the Y-direction (default of the families being placed) and the Normal direc…

Thank you @Bjorn_Keulemans1 I will test your suggestions and come back with the news.

This just got posted, I would suggest analyzing this example: [image] Adding Hangers To Racked Piping and Conduit Share Hey Everyone, since I had a lot of intrest in this topic, I wanted to send out an update on my racked piping and conduit graph. Fixed alot of bugs and go…

I noticed that the points that are not rotating correctly are with the z axis in a different direction from the others. If anyone…

@_Vijay unfortunately I was not successful with your idea. Anyway thanks for trying

What is the error or what is the problem with it…can you elaborate…so that we can try further.

Some points are not getting tangent to the curve, such as the one highlighted in the image. I was not able to discover the problem but I noticed that the points that are not tangent to the curve have their z vector 180 degrees in the opposite direction to the others. [Capture5] [Capture6]
