Disparity in solid hatch plots between LT 2020/2021

[johanask]

Hi folks,

I noticed a difference in my plots of solid hatches after migrating to AutoCAD LT 2021 recently.  I've attached examples where you can clearly see notably more distinct hatch lines in the 2021 version.

The system settings for the both versions of LT are (or to the best of my knowledge, suppoed to be) identical. Anything happened under the hood between the versions that I might be unaware of?

Thanks in advandce,

Have you recently updated your PDF software?

LT2021 uses a different newer PDF driver than LT2020: it even says so in each PDF, under PROPERTIES, see for yourself.

I'm not seeing the same issue as you are with "solid" hatch patterns here in LT2021 with my own drawings: can you share your DWG file to test? I may be missing something here on my end in my drawings.

TIA

Thanks, I havn't and I tried adjusting the settings but to no avail.

Good catch! This should then be a problem for more ppl then me, one would think.

I've attached the file for your knowledge.

I see streaking in your transparency hatched circles from PDF output in LT2021: you will need to start a support ticket at your Autodesk account to report it to Autodesk.

In the meantime using a 3rd party PDF driver eliminates the issue if these posted tips from Autodesk do not help https://knowledge.autodesk.com/support/autocad/troubleshooting/caas/sfdcarticles/sfdcarticles/PDF-pr...

Yes, I have unfortunately already tried everything in that guide. But thanks anyway, I will open a ticket and post the answer here if it gets an solution.
