Piping isometrics let the pipe be drawn by which the length, width, and depth are shown in a single view. Isometrics are commonly drawn from information on a plan and elevation views. The symbols the resemble the fittings, valves, and flanges are altered to adapt to the isometric grid.
This infographic will allow you to understand the piping coordination systems symbols for isometrics to properly fit your pipes.
The following is a transcript of the Pipe Fitting Infographic:
