NX5 Shaded Drawing--What you see is not what you get

[natlus3]

There are two issues when a particular A1 size drawing is exported to a PDF:

-the solid color shading is not completely filling the outline of the solid body
-underlying parts are partially displayed over and through other parts that are not touching.

I unchecked the Disable Full Scene Antialiasing toggle, changed the Shade Tolerance for each view to Ultra Fine, exported the PDF at High Resolution, and tried variations of all of the above to no avail. Any suggestions?

Could you post the PDF file so we could see what you're seeing (or at least a picture of the area where the problem is seen)?

To an Engineer, the glass is twice as big as it needs to be.

Attached is an example of what all circular objects look like in the 2D drawing.

I am unable to attach the actual file or screen capture, so you'll have to appreciate my MSPaint skills.

The "bleeding" of underlying parts is basically both parts showing up in the same space even though they are not touching. They're both only several mm thick, but not touching.

Are you using a lightweight reference set (faceted bodies)? If so, try changing to a more accurate solid (such as fully loading your components and using the 'model' reference set).

Is it something like this that you're seeing:

1. Make sure you're not using faceted geometry for the drawing views if you wish to maintain better quality.

2. Try View Style>Shading>Shade Tolerance

3. Try File>Export>PDF and increase the image resolution setting in the Settings panel near the lower right corner. It will make the PDF output larger but may fix your problem.

4. Post an actual example if all of the above don't work because three best guesses are my limit without actual data to interrogate.

All components are fully loaded and reference sets only contain solid geometry. I've systematically worked through most of the obvious settings in the visualization performance tool and tried to print to PDF instead of exporting to PDF. In the print to PDF function you can adjust the PDF output properties, which I've adjusted as well with no luck. Thanks for all the suggestions as they've provided a double-check that I had indeed done them.


John-

I can't see the image you posted.

I work with mining equipment and many of our parts are of incredible size. When I work with very large circles, in sketcher, the facets of the circle really make it look bad when I zoom into it.
We spoke to the TAC and the are working on a fix.
What I did notice is that when I use an arc, instead of a circle, I do not have that problem.
How large is the circle that you are showing in your picture?

Can anyone else see the image I posted yesterday?

As an alternative, I've uploaded the .jpg file below.

John,
I can't see the images you embed in your posts from my work computer, but I can see them if I log on at home. I'm pretty sure our IT department blocks photosharing sites like photobucket so those links don't come through.

 

[jerry1423]

John,
I cannot see the image that you posted at 10:58

 

[Jaydenn]

John,
I can see all your images just fine.

I suspect that it's a 'firewall' issue, which surprises me that Siemens Corporate allows it since the guys in Munich tend to get a bit paranoid over stuff like this. In the future, I'll have to remember to upload the image file itself.

John-

The shading issue is very similar to the jpeg you posted, although the facetization is contained within the outline of the object.

The bleeding, where underlying parts show through others, is different. That is where it physically looks like the two parts are sharing the same space even though they are seperated by a physical distance. In those situations, the shading is appropriately contained within the outline.

Jerry-

That sounds exactly like what we're facing here. The base diameters of the circular shapes are >100mm. I'll try recreating some of the shapes using arcs. I've noticed circular shapes don't always translate well when exporting parts to other applications.

 

[natlus3]

OK, so using arcs seemed like a great idea, but it didn't work. I got the exact same result on the drawing after I remade that part using arcs. I thought for sure it would and thanks again to Jerry for reminding me to try it.

 

[JohnRBaker]

You know, it would really help if you could provide a picture, or better yet, a simple model which exhibited this behavior.

A few more things to try:
In the visualization preferences, on the 'line' tab, try lowering the curve tolerance.
In the view style, general tab, try changing the tolerance.

I doubt it will solve your problems, but might be worth a shot.
