Yes! Thank you very much, Sebastien. I was looking for something like that. :)

At least in my version, to make it work the plugin name must be 'polylines_io_plugin' and the polyline must have an empty line in the end.

Best wishes,

David

If you create test.js with the following inside:

var testItem = "sphere.off";
main_window.open(testItem, 'off_plugin');
main_window.colorItems();
scene.item(0).setRgbColor(255,0,0);

and open the file with the Polyhedron demo you will see a red sphere
(provided that you have sphere.off at the same location).

using "polyline_plugin" and maintaining yourself the item index you
should be able to do what you want.

HTH,

Sebastien.
