Open appThe full workflow, start to finish
Nine steps from an architect's PDF to a complete load takedown. No software to install.
01
Load PDFs

02
Arrange pages
Drag to set page order and positioning across levels.
03
Scale

Pin plans to a shared origin so levels stack correctly.
05
Assign levels
Map each plan to a building level and set floor-to-floor heights.
06
Model structure
Trace walls, floors, and load zones over the plans with snapping. Auto find walls from PDFs.
07
