AutoCAD was one of the first Computer Aided Design programs to be made available on personal computers. It is built to help people design buildings, products, or public spaces, without having to draw up plans by hand. It was released in 1982 by Autodesk, Inc., and offered a personal solution to software that was before then released only for larger workstations. While CAD programs prior to AutoCAD required massive amounts of computing power in the form of gigantic computers, AutoCAD streamlined its operating and optimized it for the IBM PC, allowing people to work from home or on their own work computers.

Through the 1980s, AutoCAD functioned mostly by using simple lines and circles, and text overlays, to set up custom objects. Beginning in the 1990s, AutoCAD began utilizing more robust custom object features, built with an Advanced Programming Interface using C++. And starting in 2007 AutoCAD has had much more advanced 3D tools that allow for greater 3D modeling and exploration of models, with high-quality, fast-moving rendering.

The modern version of AutoCAD allows for much more than simply C++ programming. It has set the standard for operability in terms of Advanced Programming Interfaces in CAD, and can use VBA, .NET, AutoLISP, and Visual LISP, as well as the C++ based ObjectARX. This robust programming set has allowed for great extensibility for AutoCAD, and there are a number of more specific AutoCAD programs, including AutoCAD Electrical, AutoCAD Civil 3D, and AutoCAD Architecture.

The file format that AutoCAD uses, the DWG format, has become a standard for all CAD work. Autodesk shifts its estimates of how many DWG files are in operation in the world, but generally places the number at quite a bit more than one billion. Although a number of other CAD programs exist at this point, including programs for Mac OSX and NIX systems, AutoCAD remains the industry leader and sets a number of standards in the CAD community.

In addition to AutoCAD, Autodesk produces many other design programs, all built to help designers or architects work on specific projects. Their software is focused on all aspects of rendering, both in 2D and 3D, and they consistently seek to push the envelope on what their technologies can achieve. Autodesk software includes industry standards for animation and product design, in addition to AutoCAD itself. For example, files created with their design software may be exported and sent to prototyping facilities, which can input them into 3D printers to generate immediate 3D prototypes for an affordable fee. This seamless interaction between home software and affordable high-speed prototyping is in many ways changing the way design is being undertaken, and has largely removed barriers to entry.

AutoCAD Freestyle is built on the AutoCAD platform and is compatible with AutoCAD’s DWG file format. This means that in AutoCAD Freestyle you can open a file created in AutoCAD or AutoCAD LT add sketches, notes, and drawing enhancements and save completing workflow and round-trip with other DWG-based applications.


But while AutoCAD requires quite a lot of training most anyone can get started using AutoCAD Freestyle right away thanks to its Integrated learning tools.

When a DWG file from another application is opened in AutoCAD Freestyle, the original objects cannot be edited. That is, all geometry and text are on a locked layer.

AutoCAD Freestyle only opens one paper space layout at a time. If a DWG file created in another application contains multiple paper space layouts, the user can select a single layout to use.

DWG files created in other applications that contain 3D views may be somewhat limited in their functionality when opened and viewed in AutoCAD Freestyle.

All text, geometry, and fill elements added to a file using AutoCAD Freestyle are automatically placed on new, AutoCAD Freestyle-specific layers.

If you are an AutoCAD (or other DWG-based software application) user, and you plan to send a DWG file to a user who is unfamiliar with DWG drawings, the best approach is to create a DWG file with a single viewport in a paper space layout.

There is no way to add new symbols (blocks) to the library within the application. But the ToolPalette file AcTpCatalogacadfs.atc can be manually edited to achieve this. Dynamic blocks are supported.

AutoCAD Freestyle saves to AutoCAD 2007 DWG file format but can open AutoCAD 2010 DWG file format files. It looks like this first release is based on AutoCAD 2010 as 18.0 is the interval version number and not 18.1 as in AutoCAD 2011.

You can use this way. If you’re creating 2D drawings and 3D drawings. If you follow this way, you’re saving a lot of time.

The new way of creating CAD drawings is all about creating a 3D drawing first and then using that drawing to create your 2D drawing. In this course is explained how it is done. More. There is even explained how you can add dimensions to your 2D drawing.

Let’s make a good start. We start with creating a 3D drawing. It’s going to be a simple drawing. But that doesn’t matter.
