Process Tank Design in AutoCAD Plant 3D | Real Engineering Workflow

In this AutoCAD Plant 3D tutorial, I design a small process tank based on a real engineering project. No fluff — just a fast and practical design workflow. We start with the required working volume, define the vessel dimensions, create the cylindrical tank and support legs, and then add the required nozzles, valves, level switches, drain, vent, and outlet connection. Along the way, I explain practical engineering decisions: ✔ Geometric volume vs working volume ✔ Tank diameter and height selection ✔ Nozzle arrangement ✔ High and high-high level switches ✔ Fork-type level switch connection size ✔ Instrument clearance ✔ Stiffening ring clearance ✔ Outlet nozzle position ✔ Drain and vent arrangement ✔ Supporting heavy valves to reduce nozzle loads
