CAD (computer-aided design) software is a technology that enables designers, engineers, and architects to create precise 2D drawings and 3D models on computers. Replacing manual drafting, CAD streamlines the design process, allowing users to visualize, simulate, and modify designs with greater efficiency. It's used across various industries, including architecture, engineering (mechanical, civil, automotive, aerospace, and electrical), product design, construction, and manufacturing. CAD enhances collaboration through easy file sharing and version control, and most CAD software today is cloud-based, which means that designs are accessible anywhere.
Several manufacturers offer CAD software, including Autodesk, Dassault Systèmes, Siemens, and IMSI Design LLC. Key features of CAD software include 2D and 3D modeling, smart or automated tools, preset models, and collaboration capabilities. These tools enable users to automate tasks, manipulate shapes, check accuracy, and explore various design configurations. The price of CAD software varies widely, ranging from free, limited versions to over $5,000 per year for industry-standard software. Some popular options include AutoCAD (from $1,775/year), SolidWorks (around $3,995 to $5,490 a year), SketchUp (Pro version starting at $349/year), Fusion 360 (paid program starting at $495 per year, with a free version available for hobbyists, students, and startups) and Rhino (single-user license for $995). Many CAD software options are currently available through subscription or perpetual licenses.
