Problem when zooming in preview mode + converting to pdf (AutoCad 2023)

[chloe_bc]

Hi,

When I opened my presentation in preview mode and zoom in, lines are disappearing from my draw and there are multiples dots appearing. Also we can see behind my mask even though  I select the proper option for printing.

I also have problems when converting to pdf with the mask and added lines to my drawing (mostly smalls squares).

I'll link screen capture since it's hard for me to explain in english.

Thanks for your help!

This is not the AUTOCAD forum for users in an ARCH office: this forum is for a software called AutoCADARCHITECTURE: is that what you are using by chance? If not, for future reference the plain AutoCAD forum is over there:

if you are on a MAC, it's a different forum over here

It appears your video card may not able to keep up with AutoCAD:

Have you installed the 2023.1.5 Update yet? ABOUT command in your AutoCAD will confirm what you have installed. If not, get it from your Autodesk Account Page here https://manage.autodesk.com/cep/#products-services/updates
Restart your PC afterwards.

If that did not help... Set GFXDX12 variable to 0 (that's a zero) then restart AutoCAD2023: reverting to DirectX11 fixes similar problems for most users.

Also consider turning off LINESMOOTHING and LINEFADING variables.

If still no relief then start GRAPHICSCONFIG command and change the 2D Display Settings pulldown from "advanced mode" to one of the other choices.

If all else fails, then turn off Hardware Acceleration as a last resort, then start a support ticket through your subscription portal as explained here

Hi,

Thanks a lot for all your advices. I'm working on the plain AutoCad, I'll go on the right forum next time. 

By turning off the LINESFADING and LINESMOOTHING option, it solves problems in the preview (disappearing lines and dots). I also downgrade my GRAPHICSCONFIG to intermediate.

For the MASK, I switch my personnal ctb for the Autocad Monochrome ctb and afterwards the Mask option was working okay. I wasn't able to identified the source of the problem in my ctb... I create a new one and it was fine.

Thanks again for your time!
