👉 CAD (Computer-Aided Design) is a software-based approach to design and drafting. It helps engineers create precise 2D drawings and 3D models digitally instead of manual hand drafting.
Top Free CAD Software for Students in 2025
👉 Some free tools include FreeCAD, TinkerCAD, LibreCAD, and SketchUp Free. They are lightweight and perfect for learning basics before moving to pro software.
2D Drafting vs. 3D Modeling in CAD
👉 2D Drafting shows flat views like plans & elevations. 3D Modeling allows realistic object visualization, making it easier for engineers to simulate and test designs.
