Disappearing pipes

Revit MEP 2013

I have a sanitary system that I created and is all on the same workset. The problem I have and have never seen before is that when going from Fine Detail to Medium detail some but not all pipes disappear between fittings. When I go back to fine they re-appear. Then for no reason, out of the blue some of the pipe that disappear in Medium detail will reappear in medium but others that were visable will disappear. Also they don't plot. Very strange.

Anybody got any Ideas?

Thanks in advance,

Hi TonyVav

Is this occurring on multiple machines?  If you copy the pipes into a new project, does the same issue occur?

If you turn off hardware acceleration under Application Button > Options > Graphics and reopen the project does the issue still occur?

Do you have a certified driver installed for your card?

If you print using Vector or Raster processing by clicking Print Setup to change the setting, does either mode allow the pipes to show?

Please ensure that you have update release 1 installed as well:

Here is a wikihelp page on troubleshooting visibility issues:

Here is a youtube video on the subject:

Hi John,

I have done everything you suggest. Then when I updated the video driver to the latest 306.97 (I have a NVIDIA GeForce GT220 which came with the Dell that I have) and after redrawing the pipes that were disappearing everything looks OK.........right now.


Thanks for your help,
