Pro 3D CAD Studio

Choose a sketching tool on the left and click on the floor grid. The Rectangle tool needs two clicks for opposite corners; the Line tool lets you click a chain of points and close the shape by clicking the first point again or pressing Enter. Every new outline is instantly extruded to the height shown in the Dimension box, so a simple rectangle becomes a wall or a slab straight away. Switch to Push/Pull, click a solid and move the mouse up or down to set an exact height, with grid and vertex snapping keeping corners perfectly aligned. The Tape Measure reports distances in metres or feet, and the Move, Rotate and Scale gizmos give you precise handles on any selected object.

The right-hand inspector holds the scene outliner, layer manager, material painter and lighting controls: paint wood, concrete, glass, metal or any custom colour, then shape the scene with sun intensity, elevation, azimuth, ambient light, real-time shadows and ambient occlusion. Drag an OBJ, STL, GLTF or GLB file onto the viewport to bring existing geometry in, and export your work as GLTF, OBJ, STL or a high-resolution PNG render. Nothing is uploaded — the modelling, rendering and file writing all happen inside your browser tab using WebGL.
