While AVEVA has now moved on to E3D version 4.x and the AVEVA Connect cloud ecosystem, E3D 3.1 remains the last "legacy gold" release. Many owners (especially those in regulated industries like nuclear power or upstream oil) refuse to move to subscription-only cloud models.
Traditional modeling uses Brep (Boundary Representation), which is heavy. E3D 3.1 uses a hybrid kernel that supports both precise Brep for machined parts and lightweight graphical representation for bulk items. This allows a complete refinery model to load in seconds, not minutes. aveva e3d 3.1
Solution: Use "Proximity Detection" instead of full volume clash. E3D 3.1 introduced a "Hierarchical Clash" engine. Run clashes by zone, then sub-zone, then component. While AVEVA has now moved on to E3D version 4
The "Spec-Driven Design" is stricter in 3.1. The software now enforces bolting lengths and gasket thicknesses automatically based on the chosen specification. The auto-routing algorithm is also 30% faster, finding the shortest, least obstruction-dense path between two points in complex pipe racks. Training is required; while the database logic is
For companies still using PDMS 12.1, the migration to E3D 3.1 is a strategic project. AVEVA provides the "Migration Manager" utility. Key points:
Training is required; while the database logic is the same, the UI is radically different. Expect a learning curve of 2–3 weeks for experienced PDMS users to reach parity in E3D 3.1.
