In comparison, ‘Cloud-based CAD’ involves remote databases and vast data storage at significantly lower costs from a third-party vendor. ‘Cloud-based CAD’ allows electrical designers to share electrical drawings in real time. Electrical designers can create, read, update and delete electrical drawings, and all the changes made in drawings can be shared with other members in the team. At the same time, real-time update of ‘Cloud-based CAD’ allows electrical designers to work on the latest version of CAD all the time. In addition, electrical design rollback is available where designers can access the previous version of their work. Due to scalability and flexibility, more electrical engineers are using ’Cloud-based CAD’. Detailed key features of ‘Traditional CAD’ and ‘Cloud-based CAD’ are displayed in the diagram below.
