| # 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. |
