Hidden edges are showing up when they should not in some assemblies using "Wireframe Visible Edges Only" rendering mode.
Is this a graphics bug? I use this mode a lot for communicating design intent & it's difficult to explain these hidden artifacts to the audience.
See attached screen shots showing a good & bad example:
Good: a subassembly by itself
Bad: same assembly when it's placed in another assembly

I cannot state this is an issue with the software. I do not have that specific card on my system to test along with the dataset. I would see if other stations behave the same way with the models? Also you can see if this driver version is installed below.

Have you tried with Comaptiblity mode from Inventor Application options->Hardware?
Is this a dataset specific issue? Have you seen such problem with other datasets?
Thanks,

"IF" you are using the "autodesk certified" driver I would recommend trying the latest driver from nvidia and see if that helps..
its clearly a graphics issue and finding the right driver "should" fix the issue..
Don,
I installed the Autodesk certified driver (276.42 [8.17.12.7642]) as suggested & that did not change the problem at all (see attached image).
I'm seeing the exactly same issue as before.

Lisa,
Sorry for delay. I couldn't experiment until now....
There is no change using compatability mode, problem still exists.
I forgot to indicate that the issue occurs when I create a View/Half Section or other section. Problem goes away when section isturned off.
I have checked severaldata sets & the graphisc issue seems to happen with larger files.

Hi Gary,
It looks to me that, the problem could not be reproduced with section view and wireframe visible edges only mode, but I noticed very similar issue, when I enable Ambien shadows together. So can you help me verify whether you have enabled Ambient shadows?
Thanks,
-Lisa
Just tried another time, and it looks without Ambient shadows, there's some problem, see the picture, is this the problem the same one as you saw?
Mcgyver,
I installed latest driver (334.95) & it did not change the problem.The diagnostics say it is gold certified for whatever that's worth.
I tried to change some nVidia 3D settings specifically for Inventor using the nVidia Control Panel but that just caused Inventor to say it would not support various rendering styles such as Wireframe with Visible Edges, Realistic or Watercolor.
So I turned those nVidia setting to off (default) & Inventor works as it did before, including the exposed hidden line bug with Wireframe with Visible Edges redering style.
I see at least one other has reproduced the problem.

Hi Gary,
This seems to be a general issue of section view and Wireframe visible edges only mode, it doesn't relate with the graphics cards or drivers, with any environment the problem should be reproduced. And it should have been already there for several years. I would like to track this in our internal bug system and ask our Developer to have more investigation.
Again, thanks very much for raising this up, and please keep reporting any problems or suggestions to us.

This is a software issue, not a driver issue. It has been fixed and will be included in upcoming releases.
