rhino keeps crashing on exporting an image sampled-file

hi,

I´ve got a problem with one of my grasshopper generated rhino files. It´s probally not stricktly a GH-problem but maybe GH is the source of the problem or somebody here has expirienced the trouble I´m running into now.

I´m trying to make a patern for a screen printed window. The window measures 4,5 x 1,2 meter and had a cirle every 0.5cm, that is 216.000 different circles, generated in GH by Image Sampler.

If I save the rhino file its about 289Mb, which seems a bit large to me, since it only contains those 216.000 circles, and no other geometry. I tried rebuilding but the individual circles are already the most efficient they can be, that is point count 8, degree 2.

If trying to export this file to AutoCAD, while exporting the file crashes. So do any of you guys know how I can either make the GH-file, the Rhino-file or the exporting proces more efficient?

Thanks a lot,

Emiel

p.s. I´ve added the GH-file for reference
