ELLAH-M is a Revit productivity add-in developed specifically for structural engineers and BIM teams. Its currently published core automates structural-column numbering, foundation and pile numbering, and two-way Excel exchange. Broader tools presented on the developer’s website extend the concept toward project setup, view and sheet creation, opening and recess modeling, and future automated pile layout.
The add-in’s central design idea is continuity across the structural workflow: marks assigned to columns can drive the identification of supporting pile caps and individual piles; selected model data can move to Excel for coordination and return to the correct Revit elements; and office standards can be reused to establish views and sheets in new projects. This makes ELLAH-M less of a general-purpose utility collection and more of a structural-production toolkit centered on numbering, information consistency, and drawing setup.
Product-status distinction: Autodesk Marketplace currently presents column numbering, foundation and pile numbering, and Excel export/import as the principal released capabilities. The developer’s version 1.3.1 website also advertises Project Setup and FastVoid as available in the trial, while some page sections still label FastVoid and automated pile layout as in development. Teams should therefore confirm the exact feature set in the installed Marketplace build before relying on website previews.
Structural Column Numbering
ELLAH-M scans structural columns, sorts them according to the chosen project logic, and writes sequential identifiers directly to Revit’s native Mark parameter. The tool is intended to replace manual renumbering across multiple levels while preserving a predictable relationship between vertically aligned structural members.
Published Capabilities
- Multi-level numbering: Columns can be numbered across the full project rather than one level at a time.
- Existing-mark continuity: The Marketplace states that the tool can continue from existing manual numbering without overwriting intentional marks.
- Preview before commit: Proposed changes can be reviewed before values are written to the model.
- Native undo: Changes support Revit’s standard Ctrl+Z undo workflow.
- Structural-category targeting: The tool is described as operating on structural columns, limiting accidental edits to unrelated architectural columns or other categories.
- Flexible scope: Developer material describes full-project, single-floor, selected-range, and manual numbering modes.
- Snake Path: A newer interactive method lets the user move the cursor over columns in the desired sequence without clicking every element. Published controls indicate Space can skip a number and Ctrl can finish the path.
- Output choice: Developer demonstration material states that Snake Path can write the sequence to Mark or Comments while maintaining vertical numbering continuity across floors.
