Design the outside world with powerful and flexible features AutoCAD - one of the world's leading solutions for 2D/3D design and product documentation. Design a faster, more efficiently share data, analyze new ideas in more depth in 3D. For AutoCAD available thousands of add-ons that can satisfy the needs of a wide range of clients. It's time to design a new way - while AutoCAD.

New features:
* Reduce time-consuming due to the parametric drawings. Parametric designs can significantly reduce the scan time projects. There is a possibility of defining relationships between objects - for example, parallel lines will automatically remain parallel and concentric circles always have a common center.
* Artistic freedom: to work with arbitrary shapes. Now you can translate any design ideas, letting the will of creative thought. To create complex shapes simply move the face, edges and vertices.
* Better support for PDF. Transfer and reuse of data were surprisingly comfortable and light with enhanced support of PDF. Became smaller the size of the published files, added support of TrueType. New ability to import and use as substrates allow you to add PDF-files directly into the drawings AutoCAD.
* 3D printing of models AutoCAD. You can not only visualize projects but also to translate them into reality. Physical mock-ups of projects created by the withdrawal on a 3D printer (your own or belonging to a specialized company that provides services, 3D printing).
* Easy to create and edit dynamic blocks. Introduced improvements have helped to simplify the creation and editing of dynamic block. With its advanced mapping and allocation of objects, tools, working with dynamic blocks significantly reduce the time required to produce documentation.
