Start from something useful
Create a cube, plane or cylinder, or bring in a static OBJ, glTF or GLB mesh. Inspect the hierarchy and isometric wireframe before editing.

Simple 3D mesh editing
Start with the shape. Make it your own.
Inspect and reshape simple 3D geometry in a wireframe workspace. Begin with a primitive or static mesh, make a focused edit, and keep an editable master alongside an OBJ or GLB export.
Prototype
Windows prototype available in source. Broader hands-on editing, accessibility and clean installation checks remain open.
