The Evolution of Drafting: From AutoCAD & MicroStation to Inventor & SolidWorks

The engineering & design industry has transformed significantly, shifting from traditional 2D drafting to advanced 3D modelling. This evolution—from software like AutoCAD & MicroStation to modern tools such as Inventor & SolidWorks—has enhanced efficiency, accuracy & innovation.

Launched in 1982 by Autodesk, AutoCAD revolutionised drafting by replacing manual techniques with digital precision. It introduced features like layers, blocks & parametric constraints, improving workflow. However, it struggled with complex 3D visualisation.

Developed by Bentley Systems, MicroStation was another key 2D drafting tool, particularly in civil & infrastructure projects. It handled large-scale designs effectively but, like AutoCAD, lacked early 3D modelling capabilities.

Introduced in 1999, Inventor specialised in mechanical design with parametric 3D modelling, enabling digital prototypes, error reduction & integration with CAM software.

Released in 1995 by Dassault Systèmes, SolidWorks became a leading 3D CAD program, offering user-friendly parametric modelling, assembly design, & simulation tools for stress analysis & fluid dynamics.

• Improved Visualisation – 3D models offer realistic previews of designs.
• Better Accuracy – Parametric modelling minimises errors.
• Enhanced Collaboration – Integration with PLM systems streamlines teamwork.
• Faster Prototyping – 3D models work seamlessly with CNC machines.
• Simulation & Analysis – Performance testing before production saves time & cost.

The transition from 2D drafting to 3D modelling has revolutionised the industry. While AutoCAD & MicroStation played foundational roles, Inventor & SolidWorks have driven modern innovation. The future of CAD will likely integrate AI, virtual reality & cloud collaboration, pushing design & manufacturing even further.
