About This Tool

This tool automatically resets the pivot point of a 3D model, moving it to the center of the bounding box and aligning to the world origin. No need for desktop software like Blender or Maya. After processing, the model's positioning and rotation become predictable in slicers, CAD programs, and game engines. Supports STL, GLB, OBJ, and more. All operations run locally in your browser, no files uploaded.

About Configuration Options

General Settings

Transform Application

DefaultModify root node

Choose how the transform is applied to the model: by modifying vertices (baked into geometry data) or by modifying the root node transform. Modifying vertices rewrites all vertex coordinates and applies consistently to every export format; modifying the root node keeps the original vertex coordinates, which is friendlier to animated, skinned, or geometry-sensitive workflows. Root node transform is the recommended default.

Modify vertices

The transform is written into all vertex coordinates, rewriting geometry data; applies consistently to every export format.

Modify root nodeRecommended

The transform is written to the root node (position/scale/rotation) while vertex coordinates stay unchanged; friendlier to animated or skinned models, but formats that ignore node transforms (such as STEP) won't apply it. Recommended default.

About this tool

Why reset the pivot point?

In 3D printing and game engines, the pivot point determines how the model rotates, scales, and positions. Resetting it to the bounding box center makes these operations more intuitive. This is an online alternative to manually adjusting in Blender or Maya, saving you time.

Will the model deform after resetting the pivot?

No. Only the pivot point changes; the model's geometry, materials, textures, and other details remain unchanged. Only the spatial reference point is affected.

What formats are supported for import and export?

Supports importing STL, GLB, OBJ, and other common formats. After automatically resetting the pivot, you can export as STL or GLB, keeping or switching between formats.

How can I ensure the pivot alignment is correct?

The tool automatically calculates the center of the model's bounding box, moves the pivot to that point, and translates the entire model to the origin. You can preview the result to confirm correct alignment before downloading.

Will resetting the pivot break animations in my GLB?

For static models, the result is exact and safe. For rigged or animated files, the pivot offset is baked into the geometry rather than the scene transform, so it may affect animations. Always check the exported result in your target software before relying on it.

Why does my model import off-center in other software?

Files often store the pivot (origin) far from the geometry. Software places the model by that pivot, so the part appears offset. Resetting the pivot centers the geometry on the world origin, making placement predictable in slicers, CAD, and game engines.

General questions

Is Any3D completely free?

Yes, Any3D's core features are free to use forever. We provide format conversion, model optimization, and online preview at no cost, with no registration required.

Are my files uploaded to your servers?

No. Files you select are processed only in your browser on this device, so they never leave your device and are never sent to our servers. We don't store any user files; after processing, related data in browser memory is released.

Do I need to install software?

No installation required. Any3D is entirely browser-based; just open the webpage to use all features. It works on Windows, Mac, Linux, and other major operating systems.

Is there a file size limit?

The processing capacity depends on your device performance and the model's vertex count and texture complexity, rather than file size alone. We impose no file size limit, but when a model exceeds what your device can handle, the page may lag or even crash.
