HIGHLIGHT(OUTLINE) GHOSTING

[BWMcDowell]

Today my inventor started leaving ghost outlines of parts(in other places) on my drawing. see attached below.

Is it a view in drawing document or 3d model environment? Based on the image, it looks like a view in 3d model. Are you using express mode? Could you upgrade the video card driver to the latest one for a try again?

[BWMcDowell]

it is the 3d model and I aalready tried diver and windows updates to make sure that wasn't the culperate. also not in express mode

Hi! If you activate LOD:Master and then activate the custom LOD, does it work better?

Many thanks!

@BWMcDowell , if possible, could you share the dataset with us for investigation? email: river-yijiang.cai@autodesk.com

[BWMcDowell]

Can do, it's a 50 meg zip file do you have a ftp site, your email bounced it back

changing LOD seems to turn it off initially but it turns back on after about 20-30 minuites

[johnsonshiue]

Hi! Based on your findings, it sounds like it is indeed LOD related. Please try activating LOD:Master and do Rebuild All. Then save all files. Does it work better now?

Many thanks!

HERE IS WHAT IT LOOKS LIKE AFTER REBUILD ALL

[johnsonshiue]

Hi! Something is wrong then. Does it happen to this particular assembly or most assemblies?

Many thanks!

[BWMcDowell]

it started Tuesday and has done it on every assembly so far. the only thing I did Tuesday was the update. have you looked at the files I dropboxed?

[johnsonshiue]

Hi Brian,

Many thanks for sharing the files with me! But, I am not seeing the ghosting on my machine. I need to send the files to the project team. May I send it over? Or, the files are for me only.

Thanks again!

SEND IT TO WHOEVER

I get ghosting sometimes when assembling stuff. A wireframe rep of the part I got in stays visible where it was dropped. The actual part moves as instructed by the constrains.

I found a workaround - by accident 🙂

Since I often investigate my assembly with the section view tools, I found that 'End Section View' clears the ghosting. This command probably does a screen rebuild in the background. But why it works is less important than the fact that it works. Maybe it does the trick in your case also.

Hi Alex and Brian,

This is a known issue. It has been reported as INVGEN-30273. Based on the project team's investigation, the workaround is similar to what Alex had found already. You could force the graphics to update by switching different Visual Styles (Shaded with Edges -> Shaded -> back). The defect is currently targeting to be fixed in 2020.2. But, it may happen sooner.

Many thanks!

INVGEN-30273 is listed as resolved in 2020.2, but a problem identical in appearance remains when viewing assemblies with any visual style that includes hidden edges. The problem occurs after saving as described in 2020.1 corrupted graphics. The problem occurs irrespective of the "Display silhouette" setting within the application display settings. Entering and exiting section view clears the problem temporarily.

Wireframe shows assembly correctly

Wireframe w/hidden edges shows hidden edges with rotation and translation errors

@s_benjamin, thanks for reporting! This is a good catch, I can reproduce when saving the model with hidden edges, the hidden edges will shift position after the save. This is incorrect. I've tracked a bug INVGEN-35471, team will help investigate and find a  solution, will let you know when we have a safe fix. 

Thanks,
