I'm going to check into this. I noticed if you are placing equipment, then some pipe runs, and then select maybe a valve to place on a line, the OSNAP settings reset. This may need to go to Autodesk Dev team to be fixed. I'll let you know what I find out.
Quick question, are you all running Windows 7? Other people in the office here running Windows 7 (including me) are having OSNAP issues.
I am also having this issue, everytime I go to draw a new line, move something, or just sit idle for a few seconds my osnap settings change and my polar tracking turns off. I know its as easy as pressing F10 and going into osnap and changing the settings, but having to do this constantly every few seconds seems a bit much. My option settings are set the way I want them, but somehow P&ID has a mind of its own.. I would love to finally get a solution to this!
Also, I am running windows 7.
This appears to be fixed in AutoCAD Plant 3D and AutoCAD P&ID 2012. The only running snap that becomes active when selecting a symbol from the tool palette is the "nearest" snap. This is by design and is intended for object placement on pipe runs in P&IDs and 3D piping.
If you have any questions please reply back. If this is an acceptable solution, please click the "Accept as solution" button to help others locate this information during a search.
If you fix the nearest issue, then I will accept as a solution.
Its very annoying when trying to move/place something and nearest magically turns itself on!
Until then, this is unresolved.
Are you using AutoCAD P&ID 2012?
In 2012 and 2013 the OSNAP settings will temporarily change (nearest, node, intersection) when you select a symbol from the tool palette. Once you place the symbol the settings should go back to what it was set to originally.
