Product overview
Sand3D is a library for studying and modifying 3D objects through the programs that construct them. The official collection pairs a mesh with a Python program for each object. Parts have names, dimensions are parameters, and code describes shape, placement and material. This makes it useful when you need to inspect how an object is assembled or change its construction, rather than work only with a finished mesh.
The project describes a collection of roughly 100,000 objects recreated from several existing collections, including everyday objects, CAD parts and articulated assemblies. That number is the publisher's collection description, not an independently verified count. Its articulated examples expose joint axes and limits in code. For a useful first evaluation, select one object with recognizable parts, inspect the program and compare a small parameter change against the accompanying mesh before adopting a larger batch.
The dataset and the library that runs its programs are separate resources, hosted on Hugging Face and GitHub respectively. A library being open source does not settle the reuse conditions of every upstream object. Check the actual dataset and original collection terms for your use, especially redistribution, training or commercial delivery. This introduction reviews the published material; it does not claim that we downloaded or executed the collection.
What sand3d offers
- 01Pair 3D object meshes with readable Python construction programs.
- 02Inspect named parts and edit dimensions, transforms and material parameters.
- 03Study mechanical parts and assemblies alongside everyday objects.
- 04Inspect joint axes and motion limits in articulated examples.
A practical workflow
- 01Choose an object whose parts and intended change you can describe, and locate both its program and mesh.
- 02Read the named parameters, part hierarchy and any joint declarations before modifying code.
- 03Follow the library's actual installation instructions in your own environment; change one dimension or material at a time.
- 04Inspect the resulting geometry in the intended downstream tool, checking scale, part relationships and articulation where present.
- 05Record the dataset version, original source and applicable reuse terms before expanding the experiment.

What makes it different
Its defining representation is a program alongside a mesh: part functions and named parameters expose construction decisions. It is a dataset and supporting library for geometry workflows, so a browser gallery image should not be interpreted as a text-to-3D generation service or an independent quality benchmark.
Who should consider it
- Researchers studying programmatic 3D representations and geometry-oriented model workflows.
- Developers who need inspectable object construction examples.
- Technical artists evaluating parameter changes or downstream mesh workflows.
What to verify
- Confirm which collection an object came from and review both dataset and upstream terms.
- Check mesh format, units and compatibility with your downstream workflow.
- Verify that a parameter change preserves valid geometry and intended joint limits.
- Treat the published object counts and examples as source claims, not our measurements.
Frequently asked questions
Is Sand3D a prompt-to-3D app?
The cited page presents a code-and-mesh dataset and a library for running construction programs. It does not establish a hosted prompt-to-3D generation service.
Can I edit individual parts?
The publisher describes one function per part and named dimensions. Inspect the actual selected program to see which parts and parameters it exposes; not every object necessarily supports the same changes.
Does open source mean every object is unrestricted?
No single library label establishes all dataset rights. The page identifies multiple upstream collections, so check the selected dataset and original source terms before your intended reuse.
