Viewer
One viewer, three ways of drawing (Obliquify + Model Viewer, merged). Import a model (GLB/GLTF/STL/OBJ/PLY/3DM Rhino) and toggle the projection: Perspective (a camera with a lens), Axonometric (parallel, orbitable, flat elevations), or a true Oblique — cabinet / cavalier presets with adjustable angle, depth ratio and direction. PNG export. Client-side, nothing uploaded.
Model
GLB, GLTF, STL, OBJ, PLY or 3DM (Rhino). Drop a file on the viewer or click Import — nothing is uploaded, it's parsed in your browser. A .3dm needs render meshes saved in it (shade the Rhino view before saving); a .gltf with external textures won't resolve them — prefer .glb.
Projection
View
Front / Plan / Side keep that face true-shape while depth recedes — a correct cabinet / cavalier / planometric drawing.
