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.

Schema

column	type	notes
`challenge_id`	string	e.g. `IW0001`
`title`	string	`<collection> / <part>`
`level`	int32 (null)	difficulty tier — null (unknown)
`drawing`	Image	rendered PNG, embedded in parquet
`type`	string (null)	`MASS` / `VOLUME` — null
`value`	float64 (null)	expected answer — null
`units`	string (null)	null
`tolerance_type`	string (null)	null
`tolerance`	float64 (null)	null
`material`	string (null)	null
`material_density`	float64 (null)	null
`volume_mm3`	float64 (null)	null
`skills`	list[string]	empty list
`min_time_s`	int32 (null)	null
`max_time_s`	int32 (null)	null
`tutorial_url`	string (null)	null
`collection`	string	blueprint set / assembly the part belongs to
`source_pdf`	string	original PDF path on the recovered site
