Unusually Large PDF file size being created PDF from 3dm

Using V8 on windows 11. Unlike most of my Rhino V8 drawings I have a 3dm file that is unusual in that when I print Layouts to PDF the resulting PDF file size can be larger than the original 3dm file size. This occurs using both the Rhino PDF print function and with MS Print to PDF, so I’m assuming the 3dm file is the source of the problem, I just don’t know what to look for?

Any suggestions would be appreciated.

Turning the hatches all hatches off

image

Looks to be the Solid hatch, still poking at it.

Thank you, Is there an alternative to turning hatches off or can you suggest an alternative to using hatch?

In this case especially. It’s important to distinguish between old and New. And I have other drawings using hatch where this has not been a problem.

Changing all your Solid hatches to _Solid resolves it, something is going on with Solid.

Thanks again, however, I’m unfamiliar with what you called “_Solid” - where can I find / change that?

Found It, Worked Good, Thank you

actually its these ones, i thought they were solid, but are a dense stipple

… yes @Japhy these are the bad guys…

… found it also by examine the pdf in affinity designer:



EDIT:
each dot seams to have a diameter from 0.1mm
nice test for the graphic card.

the square of circles (3rd screenshot)
5000 curves / hatches
2mm width
1660 mm cumulated curve length

maybe a nice enhancement for the exporter ?
check short / small objects and warn if overall length / number / surface is to big ?

Ok that’s Interesting, when I printed the PDF it did take 10 times longer that some other file. I did import some Hatch files but none that were solid because Rhino already had that.

Many thanks to you both… No Program is perfect, but support for Rhino is second to none!
