Which Revit versions are supported?↓
Revit 2024 (runs on .NET 4.8) and Revit 2025, 2026, 2027 (runs on .NET 8) — all versions are included in a single download. No separate installers needed.
Is it safe? Can it damage my model?↓
Completely safe. Every operation runs inside a native Revit Transaction — one Ctrl+Z rolls everything back instantly. ELLAH-M only writes to the MARK parameter. Geometry, levels, grids, and all other model data are never touched.
Structural vs architectural columns — what's the difference?↓
ELLAH-M targets OST_StructuralColumns only — the elements placed under the Structure tab in Revit. Architectural columns, walls, beams, and all other categories are completely ignored and never modified.
How does the column numbering algorithm work?↓
Columns are sorted from North-West to South-East. The plug-in scans all structural columns across every floor, assigns sequential numbers by grid position, and writes the result to the MARK field — all in one click. You see a live preview before anything is applied.
How does foundation & pile numbering work?↓
Each pile cap is identified by the structural column it supports. The cap gets the column's number (e.g., 140), and every individual pile underneath is lettered: 140A, 140B, 140C, and so on. The system handles groups of any size — from single piles to large cap clusters.
Can I number piles that belong to the same column separately?↓
Yes. ELLAH-M automatically detects all piles linked to each pile cap and assigns a unique sub-letter to each one. The result is a complete, conflict-free numbering scheme that reflects your actual foundation layout.
How does Excel Export & Import work?↓
Export produces a formatted .xlsx schedule with Level, Mark, Section Type, and any custom parameters you choose. Import reads a .xlsx (matching the same column structure) and writes the Mark values back to Revit — perfect for syncing with external engineering software or office schedules.
Can I cancel the subscription?↓
Yes, cancel anytime directly from Gumroad. Your access continues until the end of the current billing period. Your Revit models and all data remain completely unaffected after cancellation.
Can I install on multiple machines?↓
Each subscription covers one active machine. If you need a team license or multi-seat pricing, contact us at
maor@mm-ellah.com and we'll sort it out.
