CADflow — AEC software

The tools your drawings,
and the practice around them.

CADflow builds five things for architecture, engineering and construction teams: a drafting library that lives inside AutoCAD, the same discipline applied to Revit, a door and window tool for both, an MEP tool that sizes what it draws, and the platform the office runs on between drawings. One house, one standard, one company to call.

The film

CADflow in sixty seconds.

Five products, one workflow: draw it, model it, detail it, engineer it, and run the practice around it.

The products

Five products. One drafting standard.

Each one solves a different part of the same day: finding an asset, building the model, detailing its doors and windows, sizing its ducts, pipes and conduit, and running the job around all of it.

CADBlockStudio
AutoCAD plugin
Open beta

A secure cloud library of ~2,000 drafting-ready blocks and 3D assets, docked inside AutoCAD. Search it, place it, keep drawing.

  • Correct scale and layer on arrival — no purge ritual
  • 2D blocks and 3D assets from one source of truth
  • Central updates — nobody maintains a network folder
See CADBlockStudio
BIMStudio
Revit add-in
In development

The Revit sibling. A licensed family library served through a dockable pane, loading protected .rfa files straight into the open model.

  • Its own library and taxonomy — not a DWG conversion
  • Families authored to one standard, version by version
  • Signed, short-lived downloads — never a public link
See BIMStudio
W&Dflow
Revit and AutoCAD add-in
Beta V1.075 · 3 Nov 2026

Doors and windows, forged to order: configure a unit, drop it in the wall, and the legend and the quantity schedule write themselves.

  • 98 presets, from flush doors to pivots and folding walls
  • Edit Width or Height in Properties and the unit re-forges
  • Legend, tags and schedules built from the model
See W&Dflow
M.E.P.flow
Revit add-in
Beta V1.021 · 27 Oct 2026

Ducts, pipes, drains and conduit from a few clicks: it sizes the run, checks it against the code limit, steers round the beams and builds it with every elbow.

  • Equal-friction ducts, Hunter-curve pipes, DFU drains, 40 % conduit fill
  • Fresh air, cooling load, water pressure and circuit calculators
  • Audit, schedules, single-line diagram, product library
See M.E.P.flow
AEC-flow
Web platform
In beta · live

The office around the drawing: clients, proposals, orders and projects with phases, plus the team admin that comes with them.

  • Clients, proposals, orders and projects in one thread
  • Drawings and documents attached to the job, not an inbox
  • Team, leave and practice settings in the same place
See AEC-flow
Why one house

Separate tools, same discipline.

Everything CADflow ships is built on the assumption that a drawing is a deliverable, not a doodle — and that the person keeping the library clean should not be the person billing the hours.

Drafted, not scraped

Assets are authored to a written standard — units, layers, insertion point, naming — before they ever reach a library. That is the whole product.

Licensed, not shared

Content streams to the machine that is entitled to it, over short-lived signed links. No permanent public URLs, no folder anybody can copy to a USB stick.

Built by the people who use it

Every one of these started as a problem in a working practice — the twenty unbillable minutes, the family nobody can find, the proposal nobody chased.
