Introduction:
The world engineering and construction market is dominated by two advanced 3D modelling solutions, Smart Plant 3D (SP3D) by Hexagon and Everything3D (E3D) by AVEVA. Both are developed to handle the enormous complexity of power plants, refineries, and offshore platforms, but they are based on very different philosophies. The decision between them, or between which one to become a professional, needs to be made by understanding their approach to data, automating the design processes, and fitting into the wider project life cycle.
Architectural Foundations and Data Management:
The greatest distinction between the two systems is on a deeper level in their database framework. The SP3D is constructed as a relational and data-centric database application that normally runs on either Microsoft SQL Server or Oracle. This implies that all the elements in the model consist of objects of data having distinct attributes and associations. E3D, in its turn, is the descendant of the PDMS and its hierarchical database. To further know about it, one can visit the E3D Course. This organization is extremely quick to make use of huge models and needs a novel attitude of information consistency.
- Database Type: SP3D is based on RDBMS (Relational Database Management Systems ), whereas E3D is based on a hierarchical database structure.
- Relationship Logic: SP3D is rule-based; that is, it knows automatically the relationship between a pipe and its support.
- Hierarchy Management: E3D is based on a strict World > Site > Zone structure, which allows a user to have clear control over the organization of geographical data.
- Multi-User Access: SP3D is also global in its collaboration, but the work-share of Global is incorporated in the database, whereas E3D uses dedicated “AVEVA Global” middleware.
- Data Integrity: SP3D avoids a lot of errors during the entry point due to strict rules regarding the so-called Reference Data.
- Performance and Speed: E3D is generally considered to be much faster in the response of graphical operations when a project with millions of components is considered.
User Interface and Modelling Workflow:
To the designer working with the front-line, the touch of the software is the main distinguishing factor. E3D provides an interface in which the ribbon is modern and easy to use for anyone who has used AutoCAD or recent Windows programs. The interface of SP3D is designed as a “Task-based” system, meaning that the interface varies by the discipline you are currently in (Piping, Structural, Equipment). Preparing for the SP3D Training can help you start a promising career in this domain. This maintains the workspace clean, yet it needs brain adjustment in changing design phases.
- Style of Interface: E3D has a very customizable ribbon interface; SP3D has a more classic set of menus and toolbars that are categorized by “Task”.
- Command Input: E3D has a strong command-line interface (which it inherits from PDMS) that can be used by advanced users, whereas SP3D is nearly entirely GUI-based.
- Clash Detection: SP3D does real-time interference checking; E3D usually means executing individual clash macros/sessions.
- Drafting Engine: It is widely acclaimed that the Draw module of E3D is capable of generating high-quality 2D drawings directly out of 3D data with minimum cleanup overhead.
- Isometric Generation: SP3D also closely cooperates with Isogen; E3D has its own Isodraft, also on the Isogen engine, but a different path to configuration.
- Laser Scan Integration: E3D possesses a dominating technology in the market (Bubble View), which enables designers to sculpt directly within high-definition laser scans.
Individualization and Customization Abilities:
The two platforms are extensively customizable; however, they require different CAD Administrator skills. SP3D depends on Visual Basic and .NET extensively in its automation and Naming Rules. E3D makes use of its own language, named PML (Programmable Macro Language), which is powerful and relatively simple to learn for an engineer without the need to be a professional software developer. Preparing for the E3D Interview Questions can surely help you start a promising career in this domain.
- Programming Languages: SP3D is an E3D customization that needs knowledge of .NET; E3D uses PML and more and more C#.
- Catalog Management: SP3D Bulk Load process works with Excel spreadsheets to input the data into the database, and E3D has a specific module, Lexicon, to create the specification.
- Specificity of the Rule: a violation of a rule by a design can be enforced by SP3D; E3D is based on some post-design validation and report.
- Reporting: E3D has a highly flexible, on-the-fly reporting, SP3D reporting: SP3D reporting is more powerful but generally more demanding in terms of setting up more complex SQL queries.
- Interoperability: E3D is well balanced in importing/exporting different neutral formats (IFC, STEP); SP3D is well balanced in the Hexagon “Smart” ecosystem.
- Macro Automation: The PML of the E3D can be used to create fast Add-ons, which can automate modelling workflows such as routing a pipe or placing supports.
Conclusion:
Finally, it is either a battle between SP3D vs. E3D, a rules-based or a performance-based hierarchy. Large EPCs tend to favour SP3D because they desire the system to create high standards of engineering among multinational staff to reduce human error. E3D would be a choice in projects where speed, ultra-high graphics, and integration with brownfields through laser scanning are the main concerns. With both platforms evolving towards cloud-native platforms and AI-powered automation by the year 2026, the difference in capabilities between the two is decreasing, and the decision is becoming more about the history of the project and the organizational bias than the initial technical constraint.
