Jagged lines when printing to pdf on Autocad LT for Mac

[Anonymous]

Hi all,

I'm having issues with lines turning jagged, when printing/exporting to PDF. The lines are perfectly normal in Autocad, but on PDF they turn messy and makes the document hard to read. This seems to be an issue especially near viewport edges and on certain dashed lines. When printing on paper, most of the lines look fine, but some will still have slightly thicker spots.

Has anyone had the same issue? I check the previous discussion, where the problem was solved by changing the line join style to "use object join style", but that didn't help in my case. 

Tanks in advance!

Welcome to Autodesk Forums!

Hi Marine,

Can you attach your problem drawing here?

Hi @Anonymous, 

What AutoCAD LT release are you working with? 

Does this happen with multiple drawing files? 

Does the issue show up in plot preview?

Hi Emmsleys

I have the AutoCAD LT 2016 product version M.48.M.617.

I have now had the problem with two separate files. On the previous one it wasn’t as obvious, and it resolved itself. Most of the lines affected are dashed or other special lines that are scaled. Before it has sometimes helped if I redo the line scale or redraw the lines, but it doesn’t seem to work on this file. Also, I get a perfectly normal PDF from another layout that uses the same plot style table.

The plot preview tend to crash with my current file, but with the previous one, it also showed up on the preview.

Hi, 

here is the problem file and the pen table. Hopefully there is a solution to this.

Post your PDF with the problem as well.

FWIW your file has these problems in it according to AutoCAD on my PC

Here is the pdf file with the problems. For example the border line of the plot is in very poor quality.

Hi Mari,

You forgot to attach plot style table, used in the drawing - OMA.ctb

Hi, 

Here is the ctb file. Zipped because this forum does not allow you to attach ctb files.

Forgive me, but I looked at your PDF and depending on which PDF viewer I open it in, the jagged lines are simply an on-screen anomaly you can probably fix with the display settings of your PDF viewer

There is nothing to fix with AutoCAD or your MacOS PDF driver settings.

This looks great in FOXIT Reader (another PDF viewer) for example

In Adobe Acrobat, I see more jaggies

Yes, I see the issue now.
But I'm afraid - there is no solution< because such defects in PDF output are well known issue in AutoCAD for Mac.
I also tried to output to PDF in AutoCAD for PC and jagged lines gone away.

Thanks Maxim for the answer. Good to know that there is currently no way to solve this. But this is very confusing as producing good quality pdf documents is of course a key issue when using AutoCAD in project work... I truly hope that Autodesk will work to fix this, otherwise we have to change the software we use in our office. 

Kind regards

Hi,

A few years too late to the discussion...... I came across this discussion board when searching for a resolution to the same problem, so hopefully it might help someone in the future!!

I had jagged and rough/distorted lines when printing from DWG to PDF. In the plot dialog box I clicked on 'PDF Options' and increased the dpi for 'Vector quality' and 'Raster image quality' - this worked a treat and smoothed all the jagged lines. Yes it increased the file size, but not much if you don't turn the dpi up too much.

Hi buddy, 

• Open the pdf on acrobat,
• press ctrl+k on PC or cmnd+k on MAC,
• Tick smooth line art. 

Hope this helped you.
