Create perpendicular line to an alignment

[raul.07.11]

Hi. I have a list of stations and distances to the right and left, as shown in the image.

I’m trying to create perperdicular lines to an alignment in those stations and with the distances to the right and left.
What can I do? I manage to the alignment info but can’t work the geometry nodes to create the lines. Thanks in advance.

Hi
Looking at this

Create point along alignment at a perpendicular offset

Maybe I’m not understanding the question, to what I read this is what you need, the offset is defined by you in the node parameters, I put it outside so that it does not overlap the alignment and is understandable, I hope it helps! [Cogo Points from offset]

1. Alignment.CoordinateSystemByStationOffset with the stations as the inputs
2. Point.ByCartesianCoordinates with the left and right offsets as the X coordinate input (left values should be negative)
3. Line.ByStartPointEndPoint

Why only one Coordinate System is created? Thanks for your response.

What is the output of Document.Alignments?

This is.

Set the lacing to longest.

It worked. Thanks you so much.
