This is an old thread, but I'd love to learn more about any updates in this area. I am learning Acad Electrical as we speak, and would love to know if more has been done to connect these two systems. Specifically, can you interrelate instrument tag numbers from P&ID to a schematic in Electrical?
Electrical does not use a centralize database. A database is built locally everytime a project is opened (scratch database) using microsoft access (.mdb). Data is stored inside the block attribute. So there's no sharing of database in Electrical.
On the other hand, P&ID use a centralized database which is the main storage of all the data. Which is also the reason why P&ID is slower than Electrical.
To connect these two system, it would require a lot of work. Both P&ID and electrical has options to reference other database, maybe you can look into that.
