Turn a USDZ mesh into an STP file with real CAD geometry. Flat faces, holes, cylinders and cones are recognised and rebuilt as true surfaces, so you can select, measure and edit them.
Drop it on the converter above or click browse. It opens in your browser, so nothing is uploaded.
STP is already selected. You can switch to any other output from the menu.
Click Convert. Our engine rebuilds the CAD faces, checks the solid, then your STP file is ready to download.
Other converters wrap every triangle as its own face. Open that in SolidWorks and you get thousands of fragments. We find the real shapes in your mesh and rebuild them, so holes are holes and walls are single faces.
USDZ is Apple's packaged version of Pixar's Universal Scene Description. It is what iPhone and iPad use for AR Quick Look, and what Reality Composer and Vision Pro apps load.
STEP stores exact CAD geometry: true planes, cylinders, cones and freeform surfaces joined into solids. It is the standard way to move parts between CAD systems such as SolidWorks, Fusion 360, Inventor, CATIA and FreeCAD.
USDZ files store triangles only, so most converters wrap each triangle as its own face. The STP opens, but every hole is hundreds of slivers and you cannot fillet, measure or edit anything. We analyse the mesh first and rebuild the real shapes.
Mechanical parts convert best: brackets, enclosures, mounts, gears and anything designed in CAD. Organic shapes such as sculptures and scans have few flat or round areas, so they come out as many small flat faces. They are still a valid solid.
Units are kept as they are in the file. Most USDZ files from 3D printing are in millimetres, which is what CAD programs expect.
Complex parts can take up to a minute because the rebuilding runs on your own computer. The progress bar shows each stage.
Yes. The result is a solid with real faces. Holes come out as cylinders you can select and resize, and flat walls are single faces you can sketch on or extrude.
Because they turn every triangle of the mesh into its own face. We detect the planes, cylinders, cones and spheres in your USDZ and rebuild those instead.
It will convert into a valid solid, but freeform shapes have few flat or round areas, so the result is made of many small flat faces. CAD-designed parts give the cleanest results.
No. The conversion runs inside your browser, so your USDZ file never leaves your computer.
There is no upload limit because nothing is uploaded. Very large meshes (over about a million triangles) need a computer with plenty of memory.
