CAD-40 Parametric Models

A curated collection of 40 editable, real-world CAD models across four complexity levels.

Overview

CAD-40 contains 40 independently packaged CAD assets representing furniture, tools, machines, industrial equipment, and automation systems. Every model includes an editable FreeCAD source, an AP214 STEP export, fixed-scale multi-view renders, provenance records, and reproducibility-oriented QA evidence.

Level	Effective feature count	Models	Typical scope
C	20–49	10	Compact products and mechanisms
B	50–99	10	Multi-part tools and equipment
A	100–199	10	Detailed machines and assemblies
S	200+	10	Complex industrial systems

Visual Samples

C — Wooden Folding Table	B — 125 mm Bench Vise

A — Digital Caliper	S — Six-axis Welding Robot

Quality Assurance

Every package was checked for:

• native FreeCAD model availability and successful reopen;
• AP214 STEP availability and geometry consistency;
• editable parameter/feature behavior;
• eight-view render completeness and framing;
• source identity, license evidence, and package-level attribution;
• unique project ID and local duplicate screening;
• embedded and outer SHA-256 consistency.

The final repository contains 40 unique project IDs, 40 native FCStd files, 40 AP214 STEP files, and 320 fixed-scale renders.

Licensing and Attribution

This is a mixed-license collection:

• 31 model packages are licensed under CC BY 4.0;
• 9 model packages are licensed under CC BY 3.0.

The exact license, author, source URL, attribution text, and redistribution evidence are recorded inside each model package and in model_information_batch.csv. Users must preserve the attribution applicable to each individual model.

Notes

• Dimensions use millimetres unless a package states otherwise.
• Difficulty levels describe effective editable feature counts, not manufacturing certification.
• The collection is intended for CAD research, modeling workflows, interoperability tests, retrieval, and dataset development.
