Stairstep vs Evthi

Stairs views STEP files. Open a model and inspect it in 3D — orbit, pan, and zoom, with a reference grid and a scale bar to keep track of size. Drag to orbit the model and scroll or pinch to zoom; the scale bar updates to match. The toolbar fits the model back into view and reveals an inspector that reports the geometry — vertices, triangles, materials, and overall dimensions.
