Hi I'm relatively new to gazebo and am trying to develop an indoor testing environment for an autonomous car. I was wondering if there was an simple way to develop lane markings around a set points.

Basically I have around 50 or so points (that will form the outline of a circle) in a data file, and I would like to place some object where each of these points are. Is there an easy way to do this in a world file?

Hope this isn't too vague I can add more information if necessary.
