Dynamic Display Mode Attributes Rhino / GH

hex-grids_dif_widths_dsI dug out an old C# code snippet to change the display widths of curves in the Rhino viewport, by dynamically altering the visual style attributes.

It was an answer for a question on the Grasshopper3d forum (see the thread here), so I thought of tidying up the code and posting it here (probably just to convince myself that I still have the time to be posting things).

Not much to say, just change how your curves look in the rhino viewport through Grasshopper. I am sure that someone might find it useful.

Code in Python below and the file as usual at the [Sub]Code page.
