Placement of 3D blocks along the rail alignment, including proper positioning at Rail CANT

[bairwap]

I’m working on placing 3D blocks along the rail alignment. While I’ve successfully managed to position the blocks between specific stations and along the alignment, I’m facing difficulty in accurately placing the blocks at locations where rail CANT (superelevation) is applied.

Hi @bairwap,

Maybe take a look at this thread:

Place Block along Rail with CANT

Hi, I’m currently attempting to place rail sleepers/ties along a rail alignment with CANT applied using the AlignmentExtensions.GetCantInfoAtStation node. but and struggling with orientating the block to follow the cant rotation. Any ideas please?

I have gone through this solution, but this is not working for me. I’m attaching some screenshot for your reference.

Here is the dynamo script screenshot.

Do you have any nodes that retrieve the cant data from the alignment to use for the rotation? Right now it appears that there is just a slider that apples a rotation of 0, which is why nothing is happening.

Slider is to rotate block at its axis. Could you please guide me which node i should use to get CANT information and linked with the block

This should give you what you need:
