National Informatics Centre (NIC)’s CollabCAD Group designed and developed indigenous Computer Aided Designing (CAD) Software ‘CollabCAD’ (https://collabcad.gov.in) and 3D Web Viewer ‘e-CollabCAD Viewer’ (https://collabcad.gov.in/eCollabCAD) services are launched for Atal Tinkering Labs (ATL) under The Atal Innovation Mission (AIM - https://aim.gov.in ), NITI Aayog. NIC is proud to share this software with Atal Innovation Mission under the aegis of Niti Aayog for the ATL programme. The launch took place during the Covid-19 lockdown period so that thousands of students can be benefited and can tinker at home to explore 3D digital world of product design. This release of CollabCAD for the ATL community will benefit students of more than 5000 ATL registered schools (classes 6 to 12) across the country. It provides the students with an opportunity to explore design innovation in 3D CAD models to 3D Printing with this “MAKE IN INDIA” software, CollabCAD. Access to this high-end Collaborative 3D CAD software would provide the students with endless opportunities for innovation and smarter solutions. CollabCAD desktop and network-enabled software assists product designers to create 3D parts and engineering drawings with the additional web-based 3D viewer to render models for real-time visualization for smart manufacturing. STL and CollabCAD data formats are available through export which could be visualized in a web browser environment. The CollabCAD – ATL page (https://collabcad.gov.in/atlInfo.html) has been designed for the dissemination of information to students and provides the students with various tutorials to walk through the software before they start tinkering and learning and delivering innovative models. Various 3D part files and STL files for 3D printing are also provided for quick visualization and creation of 3D print models. e-CollabCAD web application (https://collabcad.gov.in/eCollabCAD) enhanced the File upload module for ATL 3D design challenge held in May 2020. The 3D Design Challenge was launched to encourage students to learn about the technologies launched on ATL Community Day. Initially, entries for the Challenge were till 3rd May 2020, but with the extension of Lockdown and huge response from students, the challenge was extended till 17th May 2020 to give a chance for more students to participate. Three challenges were announced as a part of the ATL Community Day challenge: AI, Game Development, 3D Design with CollabCAD and results were announced in July 2020.
