- 2Watertight means every edge is shared by exactly two triangles
- 3Animations play all clips by default when present
- 4Unit-aware when the file embeds length units
About Configuration Options
Model info
File size
Total size of the uploaded model file on disk.
Data footprint
Estimated GPU usage for geometry buffers plus textures (including mipmaps).
Geometry
Vertices
Number of vertices in the mesh geometry.
Triangles
Number of triangular faces in the mesh.
Size
Bounding box dimensions in millimeters along X, Y and Z.
Volume
Solid volume of the closed mesh, from tetrahedral decomposition.
Surface area
Sum of all triangle areas (square centimeters).
Watertight
Whether every edge is shared by exactly two triangles. Open meshes may have holes or non-manifold edges.
Boundary edges
Edges that belong to only one triangle, indicating holes.
Non-manifold edges
Edges shared by more than two triangles, indicating non-manifold topology.
Mesh quality
Connected components
Number of independently connected mesh parts.
Isolated vertices
Vertices not referenced by any face.
Normals
Whether vertex normals are fully present (affects lighting).
Avg. edge length
Mean length of all triangle edges in millimeters.
Triangle quality
Mean triangle shape quality; equilateral = 100%, skinny triangles score lower.
Materials & textures
Materials
Number of materials assigned to the model.
Textures
Number of texture images embedded or referenced.
Resolutions
Pixel size and format of each texture slot.
GPU memory
Estimated VRAM used by textures including mipmaps.
Animation
Clips
Number of animation clips stored in the file.
Bones
Number of skeleton bones used for rigging and skinning.

Frequently Asked Questions
About this tool
Q
What does watertight mean?
A
A watertight (manifold) mesh has every edge shared by exactly two triangles — no holes or non-manifold edges. 3D printing and Boolean ops usually require watertight meshes.
Q
Why might dimensions look wrong?
A
If the file has no unit metadata, the tool assumes 1 unit = 1 mm. Large CAD exports in meters will look huge; scale them before printing.
Q
Is analysis local?
A
Yes. Loading and analysis run entirely in the browser. Nothing is uploaded.
General questions
Q
Is Any3D completely free?
A
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.
Q
Are my files uploaded to your servers?
A
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.
Q
Do I need to install software?
A
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.
Q
Is there a file size limit?
A
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.
