A 3D viewer that shows all your models at once
Open one file and every supported model in the same folder is listed — click to switch previews. 33+ 3D formats, Windows / macOS / Linux.
Multi-file preview
Almost every 3D viewer opens one file at a time. The Faicad 3D Viewer breaks that limit: drag in any 3D file and every supported model in the same folder is listed in the side panel — click to switch. Pick parts, compare versions, find files — in one place.
