Dear P&ID User,
during my work with ACAD P&ID 2013 following problem occured:
For some valves i need an alternative graphical symbol.
So i added the new block and symbol in the project manager. >> projectmanager >> ad symbol
If i pic the alternative symbol from the tool palette, P&ID always inserts the original symbol, not the new (alternative) symbol.
I can pick the new symbol in the drawing and change the graphical style manually at the property dialog. The new alternative symbol is now shown correctly.
But always when i change e.g. the endconnection (flanged, screwed) or modify the properties of a line (flow/Pressure, diameter etc.) the alternative symbol changes to the orignal symbol.
This problem occurs in P&ID 2013 (SP1) and 2014.
I hope anyone can help me in this matter, because i think this is a very usefull function of ACAD P&ID.
with best regards and a good start of work
Solved! Go to Solution.
When you add a new symbol, there is a Property called GraphicalStyle or similar, where you select which graphical style represents the valve you want to see.
thanks for your reply.
But as i discribed above, i already changed the graphical style using the property dialog.
The problem is, that the alternative symbol always changes the graphical style back to the existing symbol when you change e.g. the endconnections or properties at the pipeline.
I made some tests yesterday:
It seems, that using alternative symbols at the P&ID class definition "hand valves" does not work if you use the P&ID standard object classes (for eg. Ball valve etc.).
If you create your own object class (e.g. "special globe valve") you can use 2 or more different graphical styles without any problems during updating.
I hope Autodesk will find a solution for my problem.
As you're modifying valves, you need to edit the Normally property list appropriately - this is a Symbol List that defines the symbol to use for the valve based on it's open/closed state etc.
Also, you can change the graphical style of a symbol, but if the graphical styles for that block are linked to a Symbol List, then the graphic will be reset to the default upon save if not driven by a proper change in the Symbol List property.
