The editor loads after you launch it. The initial WebAssembly download is about 79 MB before compression. Use a modern browser with WebGPU or WebGL2 support.
Models are saved in this browser's storage. Export a file to keep a backup; clearing site data removes local saves. If the embedded editor cannot start, use Open full screen above.
From sketch to solid
Create constrained sketches and build exact boundary-representation solids with parametric history. Work with STEP and IGES geometry, then export models for the next stage of your design.
Model parts
Sketch, extrude, revolve, fillet, chamfer, and combine solids. Edit dimensions through the feature history.
Build assemblies
Position and constrain parts, design sheet metal, and work with schematics, boards, and wire harnesses.
Exchange files
Import STEP and IGES, export STEP or STL, and download native documents to keep editable copies.
next.BREP.io is made by Autodrop3d LLC. This free tool runs the browser CAD application; team revision control and shared document storage are available through the project's separate self-hosted PLM server.
