If you spend 12 or more hours on an airplane travelling somewhere, it’s time to write something on your blog.
I had to provide a sequence of transformations for a design at work, that could be easily manipulated by a graphic designer (change line-weights, color etc). So instead of exporting the typical raster image format from the slider animate, I wrote a small C# routine that enable to export any GH created Curve/line/ 1 dimensional object to a native Adobe illustrator file.
Parameters include: incremental export, layer name, directory to save and file name. I trust that many people will find this code snippet quite useful, as I have encountered many times this wish for vector graphics export instead of flattened images.
Please find the code and an example at the usual page.
Enjoy,
M.

private void RunScript(List<Curve> curves, int series, string name, string layername, string filepath, bool execute)
