1. Overview AVEVA E3D (Everything3D) version 3.1 is a sophisticated, object-oriented 3D design solution for the plant, power, and marine industries. As a successor to the legacy PDMS (Plant Design Management System), E3D 3.1 integrates advanced visualization, clash-free engineering, and data-centric workflows. It enables multi-discipline teams (piping, civil, structural, HVAC, electrical, and instrumentation) to collaboratively design complex industrial assets within a managed, version-controlled environment.
