MV-GEL

Multi-view CAD geometric-entity localization dataset derived from the ABC CAD dataset. Contains 5,903 CAD models, each with corrected multi-view renders, marked entity views (faces/edges), geometry files, and per-entity QA logs.

Contents

The CAD data is stored as gzip-compressed tar shards (cads_<start>_to_<end>.tar.gz), each holding ~250 model folders. Extract all shards into a single directory:

for f in cads_*.tar.gz; do tar -xzf "$f"; done

Each model folder (00000000/, 00000001/, …) contains:

• *.obj, *.step — geometry
• mesh_views_corrected/ — corrected multi-view renders
• view_*_marked_*.png — entity-marked views (faces/edges)
• views_and_ques_edge_augmented_corrected.log
• views_and_ques_face_augmented_corrected.log

Splits & mapping

• train_dataset_central.log — training model paths
• val_dataset_central.log — validation model paths
• cad_index_mapping.csv — maps each central id back to its original ABC source (new_id, source_dataset, original_id)
