Early Access

Your technical drawings,
finally legible to machines.

Vanharl reads CAD and PDF construction drawings the way an experienced planning architect and structural engineer would — and delivers clean, typed JSON or database output. No training data required.

Process

From raw drawing
to structured data.

No model fine-tuning. No labelling pipeline. Vanharl applies deep geometric and domain reasoning to understand any drawing on the first pass.

01 — INPUT

Upload Any Drawing

PDF, DWG, DXF, or scanned TIFF — Vanharl accepts every common technical drawing format without preprocessing.

02 — ANALYSIS

Architectural Reasoning

The engine parses geometry, annotation layers, symbology, and spatial relationships — the way a trained architect reads a set of plans.

03 — OUTPUT

Clean JSON or Database

Receive typed, validated JSON with confidence scores — or push directly into your PostgreSQL, REST, or custom integration.


Capabilities

Everything a senior engineer
would extract — automatically.

Zero Training Data

Works on Day One

No labelled datasets, no model fine-tuning, no waiting months for custom training runs. Vanharl reads drawings immediately — even proprietary or legacy formats.

Typed Output

Schema-Strict JSON

Every extraction returns strongly-typed, validated output with confidence scores per field — not freeform text that requires post-processing.

JSON Schema TypeScript Types OpenAPI
Domain Intelligence

Understands Construction Conventions

Rooms, load-bearing elements, fire compartments, dimensions with tolerances, elevation marks, material annotations, revision clouds — all parsed with professional-grade domain knowledge.

Integration

Fits Your Stack

REST API, PostgreSQL push, or webhook — Vanharl delivers output where you need it, ready to feed ERP, BIM, GIS, and project management systems.

REST API PostgreSQL Webhooks Batch Processing
Traceability

Every Data Point Linked to the Source

Pixel-precise bounding boxes reference every extracted value back to the original drawing, enabling audit trails and review workflows without re-examining the full set of plans.

Applications

Wherever technical drawings
become bottlenecks.

From permit digitisation to automated cost estimating, Vanharl removes the manual interpretation step at scale.

Permit & Compliance Processing

Automatically extract room schedules, area calculations, and zoning parameters from planning submissions — days of review reduced to minutes.

Quantity Take-Off & Cost Estimation

Pull material quantities, dimensions, and element counts directly from construction drawings to feed estimating tools without manual counting.

Asset & Facility Management

Convert legacy as-built drawings into structured room and system data — building a searchable, queryable floor-plan database from historic archives.

BIM Data Enrichment

Supplement or validate BIM models with data extracted from 2D drawings, filling gaps where full 3D modelling was never completed.

Real Estate Due Diligence

Automatically verify floor areas, room counts, and structural elements across portfolios of property documentation — at speed and scale.

ERP & Document Automation

Eliminate manual data entry by feeding structured drawing data directly into project management, procurement, and enterprise resource planning systems.
