Dataset Card for Shared Technical Drawings

Shared Technical Drawings

Photos and scans of technical drawings contributors may share (wiring, floor plans, assemblies), legends legible.

Collected through the Kled app by consenting contributors and licensed for commercial training. The files are delivered by Kled under license, not downloaded from this repository. Use Request a sample set at the top of this page, or write to team@kled.ai. Catalog entry: kled.ai/datasets/technical-drawings.

Dataset Details

Dataset Description

Confirm you may share the drawing, photograph or scan the full sheet, symbols, labels and legend readable. Proprietary or confidential drawings, cropped legends and low-resolution scans are sent back; 30 per contributor at most, from a global base strongest in Southeast Asia, the United States and Europe. Drawing conventions follow the contributor's country and trade, adding notational variety a single-standard corpus lacks. No symbol or region annotations are included. Engineering drawings are commercially sensitive and rarely released for training, so diagram-understanding models learn from textbook figures and synthetic schematics; the permission requirement keeps the provenance documented. A test and fine-tuning corpus for symbol detection, legend parsing and diagram-to-structure extraction in construction, electrical and mechanical domains.

Dataset Sources

Uses

Direct Use

  • Engineering symbol detection and legend parsing
  • Diagram-to-structure extraction
  • Schematic understanding

Out-of-Scope Use

Redistribution or resale of the files, use outside the terms of the commercial training license, and any attempt to identify or contact contributors or people who appear in the data. Uses that require labels this set does not carry should be scoped with the data team first.

Dataset Structure

Data Instances

One drawing per record, delivered as JPG / PNG / HEIC. Volume: 10,000+ drawings.

Data Fields

  • File: the JPG / PNG / HEIC file as captured or uploaded by the contributor
  • Labels: none; the set is delivered raw. Labeling on the same items is available on request.
  • Capture metadata: capture tool, country of capture, submission time
  • Review status: QA outcome (99%+ passed QA review)

Field names and the manifest format are confirmed with the sample set.

Data Splits

Delivered as one set. Subsets by country, language or label, and custom splits, are available on request.

Dataset Creation

Curation Rationale

The dataset exists because the public alternatives named in the description are non-commercial, synthetic, small or collected elsewhere. Kled runs the task as a paid brief in its app so that the data is captured on purpose, under the capture rules above, by people who have opted in to commercial use.

Source Data

Data Collection and Processing

Contributors complete the task in the Kled app. Capture tool: Phone camera (in app). Each submission is reviewed against the task brief; submissions that break the capture rules are rejected. 99%+ passed QA review. Files are delivered as JPG / PNG / HEIC, in the resolution noted above.

Who are the source data producers?

Kled contributors, who complete paid data tasks on their own phones. This task was open to contributors worldwide. Kled has 625,000+ contributors in 100+ countries, strongest in Southeast Asia, the United States and Europe.

Annotations

Annotation process

No annotations are included. Items are delivered as captured; labeling on the same items can be scoped with the data team.

Who are the annotators?

Not applicable; no annotations are included.

Personal and Sensitive Information

Every item was contributed by its owner, who opted in to this use at upload. The task brief states what may and may not appear in a submission, and reviewers reject submissions that break those rules. Kled's data handling practices are documented at trust.kled.ai; questions about handling requirements for your use go to team@kled.ai.

Bias, Risks, and Limitations

Coverage follows the contributor base: strongest in Southeast Asia, the United States and Europe, thinner elsewhere, and not limited by region for this task. Devices, settings and conditions vary by contributor, which is the point of the collection and also means no two items are captured under identical conditions. Where labels are contributor-entered, they are checked at review but are not expert annotations. Volumes are the current scope of the task and grow as collection continues.

Recommendations

Request a sample set and run it against your task before licensing. Ask for per-country or per-language counts where they matter to your use.

Licensing Information

Non-exclusive commercial training license; exclusivity on request. Each contributor opted in to this use when they uploaded. The license terms are on the catalog page.
