Ah – then you can use the polygons. 🙂 Orientation is relative to the line I believe…the two numbers in the .str file are the minimum and maximum offset to add to the object heading (positive numbers are clockwise)…a random value between them is picked. In our airport lights you’ll see 0 0 so that no offset is added and the lights go along the line.

The object is faced so the north side of the object is facing out along the line.

I don’t need the wires. From the air is difficult to see them, unless you are really too close, or too low. I just want to add the powerlines pylones.
With Object chain polygons, how is the object orientation ? Native (the value entered) or relatively to the line ?

I’m sorry, but you cannot – powerlines are a form of road/transportation network. You could use the polygons to place the powerline tower objects, but the polygons can’t generate the wires.

Can I use Object chain polygons to add the missing power lines in France ? A short example would be a nice start for me.

Thanks, Daniel
