Are you looking for free cad software? You come to the right place. CAD (computer aided design) software is widely used in all engineering and architecture careers to create both 2D and 3D designs. To use the software you must buy one either from prominent vendors such as AutoDesk or use free drafting software. Usually, the commercial versions of most drafting software are expensive. Don’t worry, despite some limitations you can still create drawings, plans and 3D models with free cad software.
Here I have searched the entire net and listed most of them for you.
