IFCraft — convert DWG, DXF, Rhino 3DM & LandXML to IFC (2x3 / 4 / 4.3)
IFCraft is a free, in-browser tool to convert DWG, DXF, Rhino 3DM and LandXML to IFC (IFC2x3, IFC4 and IFC4x3 / IFC 4.3). It runs entirely in your browser — no installation and no upload of your data to a server. Unlike a plain format converter it builds a structured, semantically rich IFC for transport infrastructure: CCI classification, georeferencing (S-JTSK / EPSG:5514 via IfcMapConversion), linear placement along an alignment, and the Czech DS SFDI data standard.

What is IFCraft for?
It works as an online CAD → IFC converter and generator: from your source files it builds a structured IFC model — element tree, property sets, materials, classifications, documents and georeferencing — with full control over the result. Typical use: turning design data (gantries, weather stations, speed cameras, bridge parts) into valid, semantically rich IFC without heavy CAD/BIM software.
Who is it for?
Infrastructure designers, BIM coordinators and anyone in road/rail workflows who needs to produce valid IFC according to a data standard (such as the Czech DS SFDI) quickly and without expensive tooling.

Frequently asked questions
How do I convert DWG, DXF, Rhino 3DM or LandXML to IFC online?
Open your DWG, DXF, Rhino 3DM or LandXML file in IFCraft, build the element tree and export IFC — free, in the browser, with no upload to a server.
Is there a free IFC 4.3 (IFC4X3) converter that runs in the browser?
Yes. IFCraft is free and runs fully in the browser; it exports IFC2x3, IFC4 and IFC4x3 (IFC 4.3).
Does IFCraft upload my data to a server?
No. IFCraft is a client-side tool: it processes files and writes IFC locally in your browser; nothing is sent to a server.
Which standard does IFCraft follow?
It targets the Czech DS SFDI data standard for transport infrastructure, with georeferencing in S-JTSK (EPSG:5514) and CCI classification; it exports IFC2x3, IFC4 and IFC4x3 schemas.
