This paper proposes TransCAD, an end-to-end transformer-based architecture that predicts the CAD sequence from a point cloud. TransCAD leverages the structure of CAD sequences by using a hierarchical learning strategy. A loop refiner is also introduced to regress sketch primitive parameters. Rigorous experimentation on the DeepCAD and Fusion360 datasets show that TransCAD achieves state-of-the-art results. The result analysis is supported with a proposed metric for CAD sequence, the mean Average Precision of CAD Sequence, that addresses the limitations of existing metrics.","url_abs":"https://arxiv.org/abs/2407.12702v2","url_pdf":"https://arxiv.org/pdf/2407.12702v2.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"abstracts"},"code_links":[],"tasks":[{"task_slug":"cad-reconstruction","task_name":"CAD Reconstruction"}],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[{"leaderboard":"/sota/cad-reconstruction-on-deepcad","task":"CAD Reconstruction","dataset":"DeepCAD","model":"TransCAD","rank_in_archive_order":8,"of":11,"metrics":{"Camfer Distance (median)":"4.51","Chamfer Distance":"32.3","IoU":"65.5"},"uses_additional_data":false},{"leaderboard":"/sota/cad-reconstruction-on-fusion-360-gallery","task":"CAD Reconstruction","dataset":"Fusion 360 Gallery","model":"TransCAD","rank_in_archive_order":8,"of":11,"metrics":{"Chamfer Distance":"78.6","Chamfer Distance (median)":"33.4","IoU":"60.2"},"uses_additional_data":false}],"syntology":{"syntology_url":"https://syntology.ai/paper/2407.12702","atlas_url":"https://app.syntology.ai/?focus=2407.12702","mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
