RhinoforMac - Plot line thickness/lineweight under 0.13 mm


I am currently attempting to use rhino as my main architecture CAD software. Everything works great, except in the drawing export part.
I am using print to pdf from the dialogue box that is prompted by the “print” command, from layouts.
Any lineweight set (manually, because there doesn’t seem to be a way to change the preset lineweights) below 0.13 is not being recognised and prints as 0.13.

If I export to Illustrator, it will recognize and display anything between 0.13 and 0.01.

Is there a way to make it work in rhino ? Could there be an equivalent to Autocad’s “autocadtopdf.pc3” printer emulator, which does a very fine job of plotting ?

thank you in advance.


Hi -

On the Mac, please use the ExportAll command from a layout. That will use the Rhino PDF writer and not the macOS PDF writer over which we have no control at all.

dear Wim,

thank you for your quick response.
however I have just tried using the exportall command in layout, and it still doesn‘t solve the line thickness problem.
anything above .13 shows a difference, anything bellow comes out the same.


Dear Wim,

any news from the lineweighting ?
If I insist it is only because Rhino is a dream to use and design with, and it is really just missing this “piece” to be perfectly autonomous.
Maybe I should rephrase my question more directly :

Any method to export a pdf from rhino, with a defined lineweight below 0.13 ? By exemple 0.04, 0.06, 0.1, etc ?

thank you in advance.

Dear Wim,

I hope it is okay that I bump this topic back up the thread. There was no conclusive answer previously, and perhaps I am missing something. I’m still using Illustrator as a pdf export platform, which is far from ideal.
Here are two screenshots. The first is taken from rhino, zooming in on a layout view with PrintDisplay active. You can see that the lineweights are correct. 0.01 and 0.05 clearly make a difference. The second is a screenshot of the pdf file created using the ExportAll command. You can see that the greyscale is correct, but the lineweights are all equally too thick.

I hope this is clear as a question, thank you in advance for your answer.
