Before we used Auto-Cad for creating hook up now a days we can used SPI/INtool ( Smart plant Instrumentation) Used to create Hook Up as well as all relative documents like Instrument Index, Specification sheet, Process data, Wiring ( Convention, FF, Profibus, Modbus and HART), LOOP diagram(Smart Loop, Enhanced Smart Loop), BOM and many more .. This Blog is really helpfull more .. NICE BLOG I EVER SEEN
