position 3d faces along a trajectory

[alb.to]

Bye to all,
I would like to insert in a project a parapet of which I found the block onlinethe problem is that I should place it according to curved trajectoriesIs there a way to place any already rotated mount, without having to align one by one? Is there an adaptation position?
As for the handrail I could also redesign it, without big problems, but the problem is to place the individual mounts.
Thank you.

you can use series with trajectory option, or (creating a block of the mount) divide or measure with block option.
