In Smart P&ID, all symbols and labels are embedded instead of linked, which means if the symbol/label definition is modified, user need to replace the existing symbols/labels to update the changes. Find/Replace tool with delivered software requires user to open each drawing manually, and it can only update one symbol/label each time. There is a strong demand to have a tool to update multiple symbols/labels and multiple drawing at a time. The Global Symbol Replace Utility allows the P&ID user batch process multiple symbols/labels update for one or many drawings in active project. User can select to update symbol/label with origin symbol file or with different symbol file, such as replace ball valve with gate valve. Utility will open each drawing selected, then update selected symbols/labels, then close the drawing.
