Welcome to this humble LateX package that allows you to draw Piping \& Instrumentation Diagrams (P\&ID) or block diagrams quickly and efficiently. It contains pre-built assets in pgf to create P\&ID drawings. We noticed that, with the diminishing compile time on Overleaf, it became increasingly difficult to use TikZ to this end. Therefore, we chose for pgf because it is faster to compile than TikZ objects. The objects themselves have been made in accordance with the ISO 10628-2 standard. In case you would need an example on how to use the package. You can check our Github page (https://github.com/RRaike/chempid) and the .tex files in the docs/Sections subfolders. We worked long and hard to bring this to you and we really hope that it helps your in you endeavors! If you would have any remarks or questions, then please do reach out!
