3D and CAD data from the people who model.
Geometry is hard to source with clear rights. We license 3D and CAD work directly from the designers and engineers who made it.
3D & CAD data, with proof.
Text-to-3D, CAD generation, part retrieval and spatial reasoning models need geometry that is well formed, varied and properly described. Much of the 3D content online has unclear licensing, broken topology or missing semantics. HUMXN sources models and drawings from designers, engineers and architects who have granted AI-training permission on stated terms, and commissions new work for categories, standards or levels of detail that the catalogue does not cover.
We accept and deliver common formats including STL, OBJ, PLY, GLB and GLTF meshes, point clouds and DXF drawings. Labels follow your schema: category and part hierarchies, functional descriptions, dimensions and materials, manufacturability notes, and natural-language descriptions of shape and purpose. Mechanical engineers and architects label technical work, and a second-expert pass reviews an agreed share. Paired data, such as a drawing with its mesh or a render with its source model, can be specified.
Each file is fingerprinted at intake with SHA-256 and a shape fingerprint, which catches the same geometry resubmitted under a different name, format or scale. Duplicate and conflicting claims are checked against everything registered. Origin is recorded, so procedurally or AI-generated geometry is labeled. Each item carries a signed provenance record and appears on your receipt by ID and hash, so you can show which models were in a training set.
Built to your specification.
Every engagement starts from a written spec and a pilot batch. These are the most common requests we source for 3d & cad data.
Licensed 3D models
Meshes from consenting designers across object categories, styles and levels of detail.
CAD drawings
DXF and related technical drawings from engineers and architects, with permission to train.
Point clouds
Scanned objects and spaces, with personal and location metadata removed.
Part and category labels
Hierarchical categories, part segmentation and functional labels to your schema.
Shape descriptions
Natural-language descriptions of form, function, dimensions and materials, written by experts.
Paired data
Drawings matched to meshes, renders matched to sources, or text matched to geometry.
01Unclear rights on 3D content
Much downloadable geometry has ambiguous licensing. Permission and terms bound to each file give you a documented basis.
02Duplicates across formats
The same model exported as STL and GLB looks different to a file hash. Shape fingerprints catch it.
03Technical labels need engineers
Function, tolerances and manufacturability are not visible to a generalist annotator.
3D & CAD data: asked often.
Which 3D and CAD formats do you support?
We handle STL, OBJ, PLY, GLB and GLTF meshes, point clouds and DXF drawings. Files are delivered in their source format or converted to the format your pipeline expects, as set in the specification, with metadata and labels in JSON Lines, CSV or Parquet. Large sets can be packaged as WebDataset shards.
How do you detect duplicate 3D models?
Each file gets a SHA-256 hash and a shape fingerprint at intake. The shape fingerprint identifies the same geometry when it is renamed, rescaled or exported to another format. Both are checked against everything registered, and conflicting ownership claims are held back until resolved.
Can you commission new CAD work?
Yes. Engineers, designers and architects in the network can create new models or drawings to your specification, covering categories, standards or detail levels the catalogue lacks. Commissioned work is typically licensed exclusively if you need it, and goes through the same intake and second-expert review as catalogue items.
What labels can you add to geometry?
Common labels include categories and part hierarchies, part segmentation, functional descriptions, dimensions, materials, manufacturing process notes and free-text shape descriptions. Technical labels are written by engineers or architects. Each label records whether it came from the creator, an AI suggestion or an expert review.
How is 3D data priced?
Pricing reflects source, either catalogue or commissioned, model complexity and quality requirements, format conversion, label depth, the expertise needed, and exclusivity. Detailed, engineer-labeled CAD assemblies cost more than simple tagged meshes. We quote per model against the agreed specification, with volume pricing for larger orders and standing orders.
