CAD formats: STEP / STP, IGES / IGS, DXF

So if you need an STL viewer, a GLB viewer, a STEP viewer, an OBJ viewer, an FBX viewer or a DXF viewer on Android, Open3D Viewer is one app that covers all of them.

WHO USES OPEN3D VIEWER
3D printing hobbyists check STL and 3MF files before slicing in Bambu Studio, PrusaSlicer, OrcaSlicer or Cura. 3D artists preview GLB, OBJ, FBX and DAE files from Blender, Sketchfab or Maya without booting a laptop. CAD users open STEP and DXF files from Fusion 360, SolidWorks, AutoCAD or FreeCAD on their phone. AR enthusiasts drop USDZ and GLB models into their living room.

A 3D VIEWER THAT DOES THE BASICS RIGHT
• Open files from your file manager, email, downloads, or any "Open with" menu
• Smooth orbit, pan and zoom touch controls
• Render modes: solid, wireframe, X-ray, textured, matte
• Wireframe overlay on top of the rendered surface
• Preset camera views (front, side, top, perspective)
• Light and dark themes
• 5 background colours and 6 HDRI lighting environments
• Play built-in animations on GLB and FBX models
• View 3D models in AR, placed in your real room (where supported)
• Capture a screenshot or rotating GIF and share it
• Recent files with auto-generated thumbnails
• Full model specs: triangle count, vertices, materials, textures, bounding box

BUILT FOR 3D PRINTING
If you're a maker, Open3D Viewer is the free STL viewer Android app you've been looking for. Drop in an STL or 3MF from Thingiverse, Printables or MakerWorld and check:
• Print-readiness: manifold / watertight detection, overhangs, wall thickness
• Bed-fit for popular printers (Bambu A1, Prusa MK4, Ender 3, Bambu X1C)
• Rough weight, filament length and cost estimates
• Distance measurement directly on the model
• Cross-section / clipping plane to inspect interiors
• Scale and resize before slicing
• Convert and export between GLB and STL

FREE STEP VIEWER AND CAD VIEWER
CAD files like STEP, IGES and DXF used to need AutoCAD, Fusion 360 or SolidWorks. Open3D Viewer is a free STEP viewer and DXF viewer for Android — open a .stp, .step, .igs or .dxf attachment on your phone in seconds. The geometry tessellates to a mesh so you can rotate, zoom and inspect on the go.
