Live Quantity Takeoffs for Revit

Elevating Measurement Precision

BimIndex – Live Takeoff is a Revit add-in for live quantity takeoffs and measurement visualization. It scans the active model, calculates quantities per element type, and presents the results in an interactive Live Takeoff window - review, correct, and re-export to Excel.

Imagine this...

You're in Revit, managing the bill of quantities, and the pressure is on. What if you had a live, floating panel open right next to your model? As you design, you click Update and the latest takeoff data is right there.

Even better: you click a measurement and instantly see the exact element highlighted inside your Revit model. And you manage all your project and master specifications in that same spot.

And it doesn't just measure whole objects, it digs into their DNA: precise quantities on the exact materials that make them up. Every layer of drywall, every volume of concrete, every square meter of finish, tracked automatically.

What if you could also see your live pricing right there, instantly highlighting what has changed in cost against your last commit?

While it calculates, the same panel is your automated QA checklist. It tells you, at a glance:

  • Which elements have a correct article number, and which don't.
  • Which items have the right Unit of Measurement (UoM), and which are broken.

No more manual cross-checking. No more hidden material gaps. No more pricing surprises.

And these features are just the tip of the iceberg.

It's not a dream anymore. It's here. Welcome to BimIndex – Live Takeoff. Your workflow didn't just get easier. It got bulletproof.

Everything you need for a model-wide takeoff

One interactive window, with a live connection back to your Revit model.

📊

Live Takeoff Window

An interactive grid that mirrors your model - review article numbers, quantities, units, grids, rooms and levels for every element type.

🎓

Guided Quick Lesson

First launch runs a short, stepped tour that walks you through the whole workflow - from defining elements in ITO Configuration to reading quantities, loading keynotes and tracking changes. Replay it any time from the Help menu.

🏷️

Type Management Workflow

Move element types between Pending, Defined and Excluded, assign article numbers and units of measure, and re-run with one click.

🧱

Material Takeoff

Quantify individual material layers by area or volume, with excluded layers tracked separately so nothing is silently dropped.

🔧

Pipes & MEP

Automatic article-number assembly for piping systems by diameter, with one-click exclusion of individual pipe runs.

🚪

Door Set Numbering

Assign door-set numbers per instance from a dedicated dialog, with results written straight back to your Revit parameters.

📝

Naming Convention Generator

Build a standardized type-naming template from tokens like article number, short name and description - with a live preview.

🔑

Keynote File Management

Create, edit, merge, import from Excel and load keynote files - auto-suggested keys and units of measure with a live Revit-style preview, plus change tracking that shows exactly what was added, modified or removed since your last export.

📐

QC Views & Filters

Generate 3D views and color-coded filters for Defined, Pending, Excluded and Warning elements, right inside your Revit project.

📈

Quantity Baselines & Δ Tracking

Pin a baseline at any milestone (e.g. tender issue) and the Δ column shows how every article - and every element - has moved since. A drift banner and "Δ Changes only" filter surface exactly what changed between updates.

Auto-watch & Model Changes

Switch on Auto-watch and BimIndex warns you the moment the model is edited - the Model Changes tab lists exactly what was added, modified or deleted (and who last changed it) so your take-off never goes silently stale.

📤

Excel Export

Export a full workbook with one worksheet per tab - Meetstaat, Errors, Pending, Defined, Excluded, Pipes, Materials, External Export and Door Sets.

Built for real Revit projects

Catches what falls through the cracks

The Empty Elements tab keeps every scanned element visible - nothing is ever silently dropped from the review, even if it produces no quantity.

Stays in sync with your model

Enable Sync Selection to jump straight from a Revit selection to its row in the Live Takeoff window, or isolate selected rows back in your 3D view.

Designed for Export-ready exports

Generated data and naming conventions are structured for direct import into the external estimating system, with full unit-of-measure traceability.
