MeshVault: 3D Model Inspector

STL OBJ FBX · measure & weigh

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Open a zipped assembly straight from Files - no unzipping. Pull the explode slider to separate every part, then measure it and get its weight. Open a 3D file, look at it properly, and get the numbers you actually need. OPENS WHAT YOU ALREADY HAVE STL, OBJ, FBX, PLY, GLB/glTF, 3MF, USDZ, DAE and Alembic. Drop in a ZIP, 7z or tar.gz and the models inside open directly - no unzipping first. If an archive holds a whole assembly, tick the parts you want, or load all of them at once. BUILT FOR BIG FILES A 1.2 GB assembly with millions of triangles loads without falling over. When a model is larger than the device can hold at full precision, it is reduced automatically so you still get to see it, and a banner tells you exactly what happened. EXPLODED VIEW Drag the slider and the parts move outward from the centre - the assembly opens up like a workshop diagram. Drag it back and everything returns to where it was, exactly. Files loaded together from an archive separate part by part. MEASURE AND WEIGH Tap two points for a distance in mm, cm, m or inches. Pick a material - PLA, ABS, PETG, resin, nylon, aluminium, steel, stainless, brass, copper, titanium, gold, silver, wood or your own density - and get the weight, alongside volume, surface area, bounding box and triangle count. Volume comes from the full-precision mesh, so simplified display never changes the numbers. SEE IT THE WAY YOU WANT Front, back, left, right, top, bottom, isometric, and fit to view. Lighting follows the camera, so the underside is as clear as the top. Set the model colour, the background, the light direction and its strength. CONVERT BETWEEN FORMATS Export what you opened as STL, OBJ, PLY, GLB, 3MF, FBX or USDZ. Handy when a printer wants STL and the model arrived as FBX. ALSO A WORKING ARCHIVE TOOL Extract any ZIP, 7z or tar.gz, 3D file or not, and save the contents to Files. Compress files into a standard ZIP anyone can open. Everything runs on the device. Nothing is uploaded. One-time purchase removes ads, drops the watermark from exported images, and unlocks unlimited format conversion. Free without it: three conversions, plus one more each time you watch a short video, up to five a day. Not supported: RAR archives, and CAD formats such as STEP or IGES.
