C-tubes can be understood as a generalization of Monge surfaces\u2014a special class of sweep surfaces\u2014towards the recently introduced conenets. This observation allows formulating a constructive algorithm to create tubular structures that ensures developability of the constituent surfaces, while significantly broadening the design space. Our novel form-finding tool enables design exploration by solving for the input variables of the constructive algorithm so that the C-tube best conforms to user-specified objectives. We discuss several case studies that illustrate the versatility of our approach for the design and fabrication of complex structures, with applications in architecture, furniture, and lighting design.\n                  <\/jats:p>","DOI":"10.1145\/3730933","type":"journal-article","created":{"date-parts":[[2025,7,27]],"date-time":"2025-07-27T04:02:22Z","timestamp":1753588942000},"page":"1-19","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":1,"title":["C-Tubes: Design and Optimization of Tubular Structures Composed of Developable Strips"],"prefix":"10.1145","volume":"44","author":[{"ORCID":"https:\/\/orcid.org\/0009-0009-2373-9581","authenticated-orcid":false,"given":"Michele","family":"Vidulis","sequence":"first","affiliation":[{"name":"EPFL, Lausanne, Switzerland"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8245-9568","authenticated-orcid":false,"given":"Klara","family":"Mundilova","sequence":"additional","affiliation":[{"name":"EPFL, Lausanne, Switzerland"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0952-7063","authenticated-orcid":false,"given":"Quentin","family":"Becker","sequence":"additional","affiliation":[{"name":"EPFL, Lausanne, Switzerland"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0316-1390","authenticated-orcid":false,"given":"Florin","family":"Isvoranu","sequence":"additional","affiliation":[{"name":"EPFL, Lausanne, Switzerland"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4957-4825","authenticated-orcid":false,"given":"Mark","family":"Pauly","sequence":"additional","affiliation":[{"name":"EPFL, Lausanne, Switzerland"}]}],"member":"320","published-online":{"date-parts":[[2025,7,27]]},"reference":[{"key":"e_1_2_2_1_1","volume-title":"Proceedings of Computer Graphics International (CGI '08)","author":"Akleman E.","unstructured":"E.
