This page accepts STEP models, with associated material and texture files when applicable.
Horizontal (front, right, top and perspective in a row), vertical (the same four views in a column), and custom (pick from top, bottom, left, right, front, back and perspective, with 1 to 5 columns).
Yes. The fixed direction viewports use orthographic cameras for clean technical views, with dimension lines drawn beside each orthographic viewport. The perspective viewport uses a perspective camera.
Yes. You can show or hide the dimension lines in each orthographic viewport. The unit can be toggled between mm, cm, m and in.
Yes. You can set the image background to transparent or any solid color. The margin area has its own background color setting, giving you full control over the final look.
Yes. When your 3D model contains unit metadata (from 3MF, FBX, glTF or AMF), the tool automatically detects and applies the correct unit. You can also override the unit between mm, cm, m and in.
All processing happens locally in your browser. Your files are never uploaded to any server and are cleared from memory when you close the page.
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.
No. Files you select are processed only in your browser on this device—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.
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.
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.
