Draft, model and build — with tools you already know.
CadCraft is a family of eight open-source CAD and BIM apps for architects, engineers, drafters, estimators and detailers. The commands, layers and layouts work the way your hands already expect, your drawings stay in open formats on your own machine, and every app can be driven by a script or an AI agent. Nothing has shipped yet: the CadCraft drafting app comes first, and early access is open.
Planned for macOSWindowsLinux with browser builds to follow.
The lineup
The tools you already know the names of.
Each app is named for the work it does, in the words drafters, modelers, estimators and detailers already use. Each one owns a layer color, the way a drawing set gives each discipline its own.
- CadCraft 2D drafting & documentation If you draft in AutoCAD, you already know CadCraft. In development
- BimCraft BIM authoring If you model in Revit, BimCraft will feel familiar. In development
- ModelCraft 3D modeling for design If you sketch buildings in SketchUp, ModelCraft will feel familiar. Planned
- MarkupCraft Drawing review & markup If you mark up drawings in Bluebeam, MarkupCraft will feel familiar. Planned
- TakeoffCraft Quantity takeoff & estimating If you take off quantities in Bluebeam or PlanSwift, TakeoffCraft will feel familiar. Planned
- CivilCraft Civil & site design If you design sites in Civil 3D, CivilCraft will speak your language. Planned
- DetailCraft Steel & rebar detailing If you detail steel or rebar in Tekla, DetailCraft will feel familiar. Planned
- PartCraft Parametric parts & assemblies If you design parts in SolidWorks, PartCraft will feel familiar. Planned
Principles
Rules every app follows.
Six rules hold for every app in the lineup, the way one title block holds for every sheet in a set.
-
Open formats first
DWG, DXF, IFC, STEP, PDF and LandXML in and out. Your drawings never need us to open them.
-
Works offline
Local files on your own disk, and no forced cloud. No sign-in and no license check to open a drawing or plot it.
-
Your muscle memory works
The commands, aliases, layouts and shortcuts you already use do what your hands expect. Productive in the first hour, not the first month.
-
Scriptable to the command line
Every app has a command-line interface, a JSON control channel and an MCP server, so scripts and AI agents can draft, check and plot alongside you.
-
Real desktop software
Compiled for macOS, Windows and Linux on a native geometry kernel. Not a web page in a wrapper.
-
Open source
Each app's code goes public under a permissive license when its repository opens. Read it, build it, change it.
In the browser too
WebAssembly builds are planned for most apps, for a quick look at a drawing on a machine you don't own. CivilCraft and DetailCraft start as desktop-only.
Own your drawings
-
Open formats
DWG, DXF, IFC, STEP, PDF and LandXML in and out. A drawing made in CadCraft opens in whatever you use next, including tools that are not ours.
-
Yours forever
Free and open source. If we disappeared tomorrow, the code and every file you made with it would still work.
-
No middleman between you and your files
Drawings live on your own disk. No account to open them, no upload to edit them and no subscription check to plot them.
