Converter
The converter on bitbybit.dev turns a STEP model into a GLB file for the web, in your browser - who can use it, the files it takes, the meshing and Draco options of its simple and advanced modes, and its limits.
3D Inspector
The 3D inspector on bitbybit.dev opens glTF, GLB and STL files in your browser - its scene tree and model information, warnings about heavy models, wireframe, exploded view, opacity, up axis and material variants.
