# InventorWizard Drawings

InventorWizard engineering drawings recovered from the archived inventorwizard.be site. Each row is one part/assembly drawing (rendered to PNG) grouped by its blueprint collection (machine/assembly). Answer columns (mass/volume, material, tolerance, etc.) are null placeholders for now; only the image and its collection provenance are populated.

These drawings were recovered from the archived **inventorwizard.be** website
(via the Wayback Machine) after the live site went down. Each blueprint
*collection* corresponds to one machine/assembly (the original site subfolder),
and every row is a single part or assembly drawing belonging to that collection.

> **Status: images only.** There are no mass/volume/material answers for these
> drawings yet, so every answer column is `null`. The image and its `collection`
> provenance are the only populated fields. The schema matches the other
> `drawing-to-CAD` datasets in this project so answers can be backfilled later
> without a migration.
