We have a valve symbol like the attached one. I tried to create the same with AutoCAD P&ID. But, I couldn't make the exact symbol what i wanted. I'm able to create the symbol like (3), but I want to creat the symbol like (1) & (2). Could some one pls help me to do the same? A bit urgent.
I think that the problem which you have is type of connection. In this moment is not posible to use diferent type of connection for each port.
The solution for you could be to create this valve with flanges in the same block, and don't use any type of connection(undifined type).
