Raster printing

Rhino Rhino for Windows
#1

i have a large 3d and i want to print in raster mode (i’m using “blueprint” display mode to present it directly with this style).
i don’t know how to get smooth curves, now i’m getting this result:

curiously, the first time i printed i got a best result, it would be smooth enough for me, but i don’t know how to get the same lines as the first time!

both printings are extracts from a 50x70 poster with 300ppi
i tried changing opengl antialiasing to 8x but there was no difference. i don’t know what options i have to play with the smoothness of the lines.

thanks and regards :slight_smile:

maybe moving the object close to the world origin?

#3

i centered the 3d to the world origin and nothing changed. i tried changing rhino pdf too and i get very thick lines with pdf architect and bullzip pdf.
still can’t smooth that sawtooth print in technical mode

Have you changed your OpenGL anti alias settings in Rhino?

#5

i tried with 8x antialiasing but the printing didnt change so i assumed that the antialiasing is only applied to the display view in rhino. in fact, the curves in the software are much better smoothed than the print

Hi - could you post that model?
Also, please run the Rhino SystemInfo command and copy-paste the result here.

I could send you the model in private (if possible) cause is material for a contest.
