Open PLY files right in your browser: rotate, zoom, and check dimensions, volume, and watertightness. Nothing is uploaded, your file stays on your device.
Drop a file and it renders instantly: drag to rotate, scroll to zoom, right-drag to pan, and toggle wireframe in the corner to see the triangle structure. Files that carry materials and colors, GLB and glTF, 3MF, 3DM, STEP and IGES, and colored PLY scans, render with them; the textures button switches back to the plain mesh. The panel below the viewer reports exact dimensions, volume, surface area, triangle count, and whether the mesh is watertight. Drop another file onto the viewer at any time to swap the model without reloading the page.
PLY files usually come out of 3D scanners and photogrammetry pipelines. Viewing the raw scan is the quickest way to spot holes, floating debris, and missing patches before you spend time cleaning it up.
GrandpaCAD turns a text prompt into a ready-to-print 3D model. Functional parts, organic shapes, multi-color prints. No CAD skills needed.
