issue with pdf export

[JavadM]

hi friends
i cant find any option or setting for controlling line quality for PDF export. seems anti-aliasing is not take into account.
the problem is that for "pictorial views" NX breaks non-rectilinear curves into poly-lines and results in jagged curves in generated PDF. this problem matters when i face with "Big exploded views" and creates illustrations difficulties in some view scales.

previously i used to be work with solidworks and there was options for curve qualities.

im looking for smooth curves in pictorials. can someone help me please?

Does changing the image resolution under Setting on PDF export option help? or it is still the same?

Double-clicked the exploded view. The settings window will pop up. Under Common=>Configuration. Set the Representation to Exact. If set to smart lightweight, the exported PDF would have image quality like the one you mentioned.

Hi Bwsh
in NX drawings created using 3 elements
-Text
-Curves
-Images(Logo or ...)

and unfortunately seems that only 3rd one has quality selection.
i used your instruction but the problem remains.

and with the above setting results is depicted image.

pdf export looks legacy
hope to be updated in continuous version

What do mean by drawings created in 3 elements?
-texts
-curve
-images

 

[JavadM]

in general
any drawing builds up by these 3 types

drawing views, sheet formats, title blocks and tabular notes and ... illustrated using curves and notes(texts)
any element you see on drafting. maybe images, bitmaps imported to drawing sheet or use shading for rendering style, that will result in pixel based image.
in PDF these types result in vectors and bitmaps

these 3 types are building blocks for drawings in any cad system, as i know

Then any drawing views that you created in NX drafting, you should be able to edit the view.
Where you can set the representation to Exact. When the drawing is exported out as PDF, it would be ok.
Unless the 3D models are legacy models, which I am not sure if this would affect the views created in NX drafting and thus PDF export quality.
Any pictures, images inserted into NX drafting view won't work even if the representation is set to exact.

Contact GTAC if you still not able to fix the issue. Have them taken a look on your drawing file.

There is also option in plotting which have impact on exported pdf file. In file-> utilities -> customer defaults -> gateway -> plotting -> general change tolerance to 0,001 (mm), then save and restart NX. Then try again export pdf, It should help.

With best regards

It seems that the images you show here are heavily zoomed. - The line thinkness and the shape of the line ends shows that. In a pdf, the line thinkness is fixed and will scale with the zooming.
In NX , the lines will not get thicker when zooming.

Is your intended process to export a small scale pdf out from NX and then zoom heavily in pdf before doing something further ?
- A pdf/plot/print will always have quality issues when zoomed. The default accuracy of the pdf/plot/print is intended for being viewed printed 1:1 on paper.
I.e, when you have a pdf, print that 1:1 and then , look at the printed paper for errors or deviations.
If your intention is to zoom the pdf and then do something further , you either need to export a larger scale , or set the ,probably, plotting tolerance.

Also , have a look at the CGM export settings, i think NX uses a cgm file as intermediate format when exporting to pdf. ( This might have changed in later releases but did use CGM back in time.)

Regards,
Tomas

Not sure if the following would help print image or not, but I know for modeling, the following helps smoothen the image of the model out:

View -- Visualization Preferences -- Faceting - Then set Facet Scale = View and Click to make check mark present at the Align Facets along Edges check box

Hi Friends
Thanks for response.

Actually, I asked for provide an exploded view in PDF format that can be used for downstream presentation purpose. So because of huge number of components I reduced the view scale that can be fit in paper (A1 landscape). after zooming on screen, accidentally I noticed strange illustration about arcs and circles in PICTORIAL views. Seems NX converts non-rectilinear curves to POLYLINES in pictorial views. this is not about specific drawing.

also there is no problem on prints but I was searching for tweak this issue if it’s possible.

Best regards Michael, I changed tolerance to 0,0005(mm) and curves look much better, but yet are polylines.
Great Tomas, the images were heavily zoomed and plotting tolerance helped as Michael mentioned.
Dear Brent, faceting setting won’t help in this case

Finally, I found in DWG format, the illustration for pictorials is correct and ARCs remain safe in exported file.

Thanks all
Best regards
