Product

One model, linked views

ArchBuilder models measured walls, curtain walls, doors and windows, slabs, roofs, stairs, lifts, ramps, rooms, and furniture across multiple buildings and storeys. Plan, 3D, section, and sheet views share one model, so an element selected in one view stays selected in the others.

Architecture

Account-free, offline, and open-core

The Apache-2.0 open core is split into model, geometry, command, family, storage, and interoperability packages. The editor works offline without an account, stores projects locally or in portable .archbuilder files, and exports native IFC, DXF, and vector PDF. Optional sync, an AI extension API, and a Windows package are being developed in stages.
