To simplify the process of creating a technical drawing, 2D CAD software generally provides drawing tools, pre-defined symbols for annotations, specific objects, various line options, and dimensions.īased on this understanding, we put together the following list of the best free 2D CAD software available in 2023. Understanding how to use 2D CAD is a requirement in a variety of professions such as mechanical engineering, design, and architecture. Likewise, it is not necessary to model an entire floor plan in 3D - such as doors, windows, furniture, and all other essential elements - when it is possible to simply produce a top-view layout that employs symbols to indicate locations and dimensions of the floor plan.

For example, if you are CNC milling a flat object such as a business sign, you only need to create the object from one view point.

There are several practical applications for limiting your design to two dimensions. This contrasts with 3D CAD, where the projected views are generated using a 3D model of the object on three planes (x, y, and z-axes). 4 Which Free 2D CAD Software Is the Simplest to Use?ĭrawing the projected views of an object on two planes (x and y-axes) without creating a 3D model is known as two-dimensional computer-aided design, or 2D CAD.3 Why Should You Try 2D CAD Drafting Instead of Manual Drafting?.
