An in-browser measurement engine for quantity surveyors and builders. Open 2D and 3D drawings, take off quantities, count items automatically and push accurate data straight into your estimating workflow — no installs, no plugins.
Plans open directly in your browser — no installer, no plugins, no downloads. DimensionIQ is a WASM-first viewer for 2D and 3D drawings that loads straight from the cloud.
Under the hood, DimensionIQ handles user interaction, geometry and measurement logic. Your app handles storage, business logic and UI. A clean JavaScript API lets you create, update and manage dimensions programmatically — bulk imports, event-driven updates, synchronisation across tools.
From single-click length measurements to full BIM extraction from 3D drawings, DimensionIQ brings the familiar tools of the trade into the browser — faster, cloud-native, and ready to integrate.
Click once to measure. Point, line, polyline — DimensionIQ handles scale, units and rounding automatically, with every dimension saved to a named group for later.
Trace any closed region on a drawing. Wet areas, flooring, footprints — areas are returned instantly in m², with dimension groups and quantities ready for export.
Draw a template once; DimensionIQ finds every match across the plan with a confidence score. Tune the match threshold, review, accept — hundreds of counts in seconds.
View 3D models alongside 2D plans. Read and extract BIM metadata — layers, materials, properties — and feed them into measurement groups or your estimating tool.
Overlay revisions, highlight changes, re-measure only what moved.
Native support for construction file formats — no conversion step.
Embed the engine into any estimating product — cloud or desktop.
Organise measurements by trade, room or category with one click.
DimensionIQ was founded by the team that spent decades putting on-screen take-off into quantity surveying offices around the world.
The result is DimensionIQ: a cloud-native measurement engine written from the ground up for modern web technologies, so any estimating product — cloud or desktop — can deliver world-class take-off.
