How to draw parallel lines

[sachi]

Dear all,

I’m working on a school project. I’m developing a 3D model using Sketchup through Ruby extension. I want to draw a parallel line for a curved line.

The curved line was drawn using Ruby API command entities.add edges. The points of the curved line were provided by a Ruby array.
Now I want to draw a parallel line for this curved line. Do you have any suggestions please?
Thank you

Smustard.com's offset.rb adds an ' .offset' methods faces/edges/arcs/curves etc. That should give you some ideas at least...

My ExtrudeEdgesByOffset tool also has some similar code that you could think about - however the easy way to offset edges is if they belong to a face, and are therefore definitely coplanar...

Instead of entities.add_edges(array) you might be better using entities.add_curve(array) to make the offsetting easier, if you want separate edges later you can always explode the curves in code...
