A two-storey load takedown from an architect's PDF in under five minutes. Watch the demo, then try the built-in example yourself.
Open appThe full workflow, start to finish
From an architect's PDF to a complete load takedown with 3D visualisation and detailed results. No software to install.
01
Load PDFs
Import single or multi-page architect plans directly in the browser.
02
Set up levels
Arrange pages, set scale from a known dimension, and assign each plan to a building level with floor-to-floor heights.
03
Align plans
Pin plans to a shared basepoint so levels stack correctly.
04
Model structure
Trace walls, floors, columns, beams, and load zones with snapping. Use AI wall detection to auto-find walls from PDFs.
05
Review in 3D
Visualise the full building in the interactive 3D viewer. Check load paths and element connections across levels.
06
Live results
Tributary areas calculated automatically. View detailed wall cross-sections, load diagrams, and per-element breakdowns.
07
Annotate
Add markup, dimensions, and notes directly on the plan using the built-in drawing tools.
08
Export PDF
Download a complete PDF calculation pack with load diagrams, results tables, and annotated plans.
