AutoCAD 2012 improves the way you have to interact with the software from design to finalization. With significant improvements in performance, extensive online resources, and accelerated, intuitive access to commands and editing tools, you’ll spend less time worrying about the software and more time to advance your drawings, Is at least what we are promised.
User Interaction and Modernization
Performance improvement
AutoCAD 2012 offers you improved performance in several areas. For example, you will start faster, especially if you are using Vista or Windows 7. When you launch AutoCAD 2012, you will see almost instant answers as you browse the ribbon tabs. AutoCAD 2012 also offers improved performance when you open large 3D drawings and navigate through these 3D drawings. You will also see improvements in performance in the selection of objects and in the execution time of LISP routines. It will be interesting to test these assertions of the editor, the task being tricky, because all this depends on the work environment, hardware and software.

Content Explorer
Instantly find object-based content in text drawings and attributes. Autodesk Content Explorer (formerly Project Snap from Autodesk labs) create an index of your data based on the locations you specify, helping you quickly access your files. You can explore and navigate DWG drawings to access and insert blocks, layers, line types, styles, and much more. Unlike the Design Center, Autodesk Content Explorer is based on a Google type index, so that you can quickly search for drawing objects in directories containing thousands of files, with the results appearing instantly. In addition, Autodesk Content Explorer provides you with a single interface for browsing and searching for other data sources such as Autodesk Seek. Google is therefore emulating. We can only welcome that. Will Google’s philosophy and trademark be respected here? Did Autodesk keep simple and powerful search capabilities? This is the challenge of this new feature.

In the Content Explorer window, use the search box to find design content on your local computer, on one or more network locations, and on the Autodesk Seek site. A drop-down menu allows you to choose the data sources.

You can locate specific block references or character strings, including block attribute values. Quickly determine how many references there are in a file or find a particular reference in multiple files. Easily drop content from content Explorer in your current drawing. You can also right-click or double-click on the contents of the Explorer account to automatically open the source file and zoom in on the appropriate objects such as text.

You can deploy and collapse each panel in search results to easily view your results. Check the content type and the format in which it is displayed using the filter settings and display options in the bottom right corner of the Content Explorer window.

For example, you can filter content so that your search results show only the types of specific objects you are interested in. Switch between the detailed view and the preview view, specify the size of the icons, group the results in several ways, and choose whether or not to display text labels and column headers.
Content Explorer searches content in specified placements that are included in an index. Their activity is continuously monitored by a service, which is installed with AutoCAD, and this index is automatically updated to reflect the changes. By default, the search index includes AutoCAD sample drawings and downloaded content directories, as well as the Autodesk Seek site. You can easily add your own local content and your servers to the index.

The interface of the ribbon
The improved ribbon interface makes it easier than ever to identify and access the most commonly used tools. The Home tab includes changes to the Draw and Edit panels.
The Insert tab now has Block and Block Definitions panels. The tools for inserting and editing block references are grouped together and the tools for creating or editing block definitions are also grouped together. The Wbloc command is included in the Block Creation drop-down panel. The display tab includes a new “forward” tool and a rectangular window option has been added to the window pane. Those who have waited for twenty years the icon Wbloc are now filled … You see, nothing used to be impatient. Have you noticed a bit of irony in this last sentence? You are not wrong.

Multifunctional handles
The power of multifunction handles has been extended to several other AutoCAD objects including lines, arcs, elliptic arcs, dimensions, multiple landmarks, and also 3D faces, edges, and segments. You can access the settings options for these handles by moving your cursor over a handle.

Using the dynamic input multifunction handles lets you edit the object with appropriate dimensioning values. For example, when you choose the “Extend” option for a selected row, the dynamic input dimensions for the total length and the incremental length are displayed. You can use the handles to toggle between the two values. Similarly, elliptic arcs have been enhanced to support dynamic input with respect to major and minor axes. When you move your cursor over a quadrant handle with the dynamic input, distances from the center of the quadrants are displayed along the major and minor axes. If you click on the handle, you can edit the values.

Autodesk’s intent is commendable. It remains to be seen whether the addition of features perpetually present in front of the user will not make the interface more confusing. It is true that it is often possible to disable this kind of functionality, but we would rather, instead of having to disable them, have the choice to activate them. One option might be to enable these default features and ask the user, at first use, if they want to continue using them.

3D Associative Network
The feature of associative networks, which is so interesting in 2D is also useful in 3D modeling. Each of the three types of associative networks, rectangular, polar, path, includes the possibility of networking selected objects in a 3D space. Use the level option to specify the number of elements in the Z direction during or after network creation.

AutoCAD 2012 introduces new options like chain or loop to simplify the process of selecting contiguous edges or curves. Other improvements also make it easier to work on 3D solids,

The Autosnap 3D marker
The Autosnap marker in the Options dialog box and renamed Autosnap 2D marker and a new control for the Autosnap 3D marker is added. With different colors, you can more easily distinguish between Autosnap 2D and 3D markers in the editing window.

Imports of 3D models
You can now import several 3D file formats such as CATIA, NX, Parasolid, Pro / Engineer, Rhino, and SolidWorks.

Documentation of the model
Save time by automatically generating intelligent documentation for AutoCAD, Inventor, and other models. Drawing views, edges, and placements are automatically updated when an engineering change is made.
Access the model documentation tool from the drawing view panel and the ribbon annotation tab.
In general, AutoCAD 2012 brings a lot of improvements in the design of 3D objects and especially their presentation in paper space. They’re getting closer to Autodesk Inventor, which has several features.
