ArrayCrvOnSrf Orientation

Hi guys,

I hope someone can help with this. I’m trying to model railway tracks on uneven ground. I thought ArrayCrvOnSrf would do the trick but I’m struggling.

Is there a way to set the orientation of the arrayed objects?

Does the command not work for polylines on the polysurfaces? I had to explode the curve to get a result.

Is there another command to use to get the rails (ArrayCrvOnSrf has frustrated me enough today?)

I’ve added a link to a video to show how I went about it below.

Btw, is there a maximum file size to upload to this forum? I couldn’t upload the video directly.

Thanks in advance

Hayden
