An open-source SketchUp-style solid 3D modeler

About

A free 3D modeler that adopts the SketchUp workflow of drawing on faces and shaping with Push/Pull. Aimed at SketchUp users in woodworking, architecture, the maker community, and similar fields
Tool names and shortcuts such as Push/Pull, Follow Me, Offset, Move, Rotate, Scale, Tape Measure, Protractor, and Section Plane, as well as inference snapping to endpoints, midpoints, and axes, are nearly identical to SketchUp. Typing 3x or 3/ after a Move creates an array copy
Solids-first design: each Push/Pull creates a separate closed object that does not merge with neighboring objects, and each object shows in real time whether it is a solid. Combining is done explicitly with the Union, Subtract, and Intersect commands
A clean-room reader/writer opens .skp files from every version from SketchUp 3 through 2027 and can save them back in their original version. Supports COLLADA .dae import and glTF/STL/3MF/USDZ export
Its native .hew format is a documented zip bundling JSON and geometry buffers
Supports groups, components, tags, scenes, an outliner, materials and textures, dimensions and leaders, 3D text, and true-scale printing to paper or PDF
Offers native apps for macOS (Apple Silicon/Intel), Windows, and Linux, plus a web app (app.hew3d.com) that uses the same kernel. Shop Mode lets users view models on a phone, and it can also be self-hosted in a home lab
No subscriptions, accounts, or paid tiers. AGPL-3.0 license
