Add comments and annotations to drawings, anywhere, easily and without requiring the drawing to be open. Review and customize drawings from within AutoCAD. (video: 1:38 min.)Code and document formatting tools make it easy to cross-reference and comment on code, even in legacy drawing files.3D preview:Compare drawings side-by-side in a 3D viewport. Generate a 3D shape from one of your shapes. (video: 0:45 min.)Visualize geometric properties such as area, length, center and angle of 3D elements. (video: 1:10 min.)Parameter-driven modeling:Use properties like dimensions, scales and angles to define the parameters for your model. Modeling parameters like these make it easy to reuse your designs in multiple applications. (video: 0:58 min.)Create and edit applications. Export and import your data directly from drawing files. View and edit CAD models in a web browser. (video: 1:30 min.)CAD/CAM:The control flow interface provides the highest level of automation, while also offering full control of any step along the way. AutoCAD uses the control flow interface for the majority of its operations, so you need only to learn a few simple steps to quickly perform tasks without thought. (video: 1:06 min.)Vector-based drawing. These features help you create and edit complex vector graphics and spline meshes. (video: 1:33 min.)Create, edit and annotate geo-data using the new Geo-data Tools. (video: 1:16 min.)Automatic centerline, polyline and spline definitions. These tools provide an intuitive, auto-complete interface to these complex elements. (video: 0:57 min.)2D ortho-viewing:Automatic placement of AutoCAD map views. This tool lets you create many views of a map at the same time from a single coordinate, or set of coordinates. (video: 1:03 min.)New 2D drawing tools for plotting images and maps, and converting between graphics file formats. (video: 1:25 min.)Unlimited number of layered drawing views. These tools make it easy to find the view or 2be273e24d
