8 Great Free 2D CAD Software 2021 (Beginners & Experts)

Designing accurate blueprints and complex drawings used to be all done by hand, with sets of rulers, protractors, and other measuring devices requiring immense dexterity and a keen eye to use well. 2D CAD software has made that a thing of the past.

Unlike 3D CAD software, which is used in processes like 3D printing, 2D CAD software is used to design 2D objects like drawings or top-down models. These designs include blueprints, floorplans, and artistic endeavors like graphic design or comic creating.

What is 2D CAD Software?

2D CAD software refers to computer-based software used to create designs that only require the length and height of a project, without needing the depth of a 3D model.

While freehand artistic tools work well for more artistically creative projects, 2D CAD software needs high-level precision to be usable in planning out blueprints for buildings and interior decoration, which require accurate measurements.

Such measurements are often difficult to get exactly right by hand, and almost impossible for those not used to such design methods. This is where 2D CAD software can be a lifesaver for people who need precisely laid-out structures in reliable settings.

2d cad software

Those used to 3D CAD software will know how useful base views can be when perfecting each side of a model. With 2D CAD software, you can turn this base view into a full design. This is especially useful for interior designers who want to turn 3D models into a 2D floor plan.

2D CAD design is used for laser cutting too, as it tells machines what patterns need to be cut to precise measurements, turning complex patterns and imaginative works into physical objects from computer-designed files.

What is the Best 2D CAD Software?

The best 2D CAD software for you all depends on what you need it for. Some are geared towards interior design, while others are best suited to mechanical and construction projects, and can also be used for laser cutting and engraving, or CNC.

Some software is geared towards architecture, others have more creativity in mind. If, however, you’re looking for more versatile software, you can check out our other rankings for things like the best graphic design software.
