What’s New in E3.series 2026

Faster variant switching in large projects: Activate and deactivate options with significantly improved performance and reduced loading time

Enhanced Variant and Option Management

Managing electrical projects with extensive variants and configuration options has become significantly easier. The updated variant handling functionality includes a redesigned user interface with better structure, faster filtering, and improved performance for large datasets. Engineers can now visualize, select, and manage variant-specific logic more clearly—supporting product platforms with hundreds of configuration options. This enables faster iteration and reduced errors in variant-rich industries such as machinery, automotive, and aerospace.

Easily find and update attribute values or texts using the main menu or Ctrl+H. Highlighted results, smart filtering, and support for case-sensitive search streamline editing across complex designs.

Precision Editing with Search and Replace

A redesigned search-and-replace tool allows high-precision updates to attributes, texts, and metadata across entire projects. Users can apply powerful filters and conditions to control which objects are affected, minimizing the risk of unintended changes. This is particularly useful for global naming updates, compliance-driven attribute changes, or bulk edits after library updates. Combined with the new selective component update function, teams can implement changes in a controlled way without disrupting validated design sections.

Device names can be generated based on either “Higher Level Assignment” or “Location” using separate configuration checkboxes

Automatic Naming of Mating Connectors

Connector device names can now be generated automatically based on configurable rules such as hierarchical level assignment and location. This eliminates manual naming effort and improves consistency—especially in large-scale designs with high connector counts. By automating the naming process, engineers can ensure alignment with internal standards and reduce the risk of human error, helping to maintain clean, structured data for downstream processes such as ERP integration or harness manufacturing.

Auto-rotation of components: Devices are now automatically aligned based on their mounting position, ensuring correct placement on sloped or angled surfaces

Smarter Cabinet Layout and Placement

The panel layout workflow has been significantly enhanced with smarter component behavior and more robust 2D/3D synchronization. Components can now auto-rotate to align with angled surfaces during placement, and STEP model imports offer more control, including the ability to skip or cancel individual files mid-import. Users can also resize multiple devices at once and manage complex assemblies with greater flexibility—reducing time spent on repetitive layout tasks and improving design accuracy across layout revisions.

Automatic connector alignment, smarter harness flattening, and enriched metadata exchange for seamless cross-domain collaboration

Better ECAD-MCAD Integration

Cross-domain collaboration between electrical and mechanical design teams is enhanced through updates to E3.3D Transformer and the E3.3D Routing Bridge. Features such as automatic connector alignment, improved flattening of harness paths, and enriched metadata exchange reduce the effort required to coordinate 3D mechanical constraints with electrical intent. These updates help ensure that wire lengths, routes, and spatial constraints match between ECAD and MCAD environments—lowering the risk of integration issues during physical prototyping and final assembly.
