Takeoffs

Tangible replaces manual measurement with an AI-driven workflow. The Takeoff Agent reads your design documents, maps every building element to a standardized assembly, and outputs structured, traceable materials data — ready for estimating, carbon reporting, or design comparison.

1Quantify

Extract quantities from models or add them manually, and map elements to assemblies

2Customize

Refine each assembly with design details from PDF drawings

Structured material data, ready for estimating and reporting

Quantify

The Takeoff Agent structures every building element as an assembly — a layered data model that defines exactly what a building element is made of. A wall isn't just "a wall." It's aluminum panels, insulation, a vapor barrier, studs, gypsum board, and paint — each tracked as a separate material with its own quantity and classification.

Tangible's Assembly Database contains standardized assemblies for walls, slabs, roofing, glazing, and more. The agent maps each element from your model to the best match, then fills in every material layer — including the ones the 3D model doesn't contain. For elements outside the model, you can add quantities manually.

Customize

Each material in an assembly starts with a default — a Tangible assumption based on the assembly type and industry standards. When the agent finds more specific information in the PDF drawings (a spec sheet callout, a wall section detail, structural notes), it customizes that material to match the actual design intent.

Common customizations include stud spacing, insulation thickness and R-value, concrete strength, and specific product selections. Anything the agent doesn't find in the drawings stays at the default, which you can always override manually.

Variables are reusable assumptions (e.g., "steel density" or "rebar %") applied in quantity formulas to keep calculations consistent. Variables can be overridden to match design intent or left at their defaults.

Every takeoff starts from smart defaults, then adds customization where you need it.

  • Project-level — Make one-off edits on a project: swap a material, override a variable, or adjust an assembly when the design or your review calls for it.
  • Organization-level — Share your standard products and design assumptions with the Tangible team. They apply those choices when running takeoffs so outputs stay consistent across projects. (Coming soon) Self-serve workspace settings to manage organization defaults directly in the UI.

Use

Each assembly is encoded using industry-standard classification systems — MasterFormat and Uniformat — so the same data can be organized for estimating, sustainability reporting, or specification tracking.

Sample data from a Tangible project. 14 of 42 assemblies shown.

Tip: The agent works best when both the Revit model and PDF drawings are uploaded. PDFs provide design context — concrete strengths, wall assemblies, material specs — that the 3D model alone may not capture.

Common questions

How accurate are the AI takeoffs?

The Takeoff Agent maps every Revit family to a standardized assembly. The Tangible team verifies each takeoff before delivery, and you review key decisions at checkpoints. Every quantity links back to its source — model geometry, PDF callout, or Tangible assumption — so you can trace and adjust anything.
