Computer-aided design (CAD) is a process that allows computer users to design a variety of products and geometric shapes on-screen, rather than building them by hand. Using CAD software, one can create and modify an object to determine how it will appear and function after it is built. CAD drawings often include a computer-generated image of the design, as well as its dimensions, processes, and materials. CAD drawings may be either two dimensional (2D) or three-dimensional (3D). When an object is drawn in 3D using CAD, the process is often referred to as rendering or modeling, while 2D design is often called “drafting.”

CAD drawings are used in a large number number of industrial and manufacturing applications. This technology is widely utilized in art and graphic design, and gives these artists a greater level of design flexibility than that of other mediums. CAD drawings are also used in automotive and aerospace design, as well as in the development of industrial products and equipment. Many special effects used in films and television rely on computer animation generated with CAD software. Finally, CAD drawings are a critical component of the construction and engineering trades.

Before the invention of CAD, products and building plans were drawn by hand. This was a laborious and time-intensive process that required a high number of draftsmen, as well as frequent revisions. With the introduction of CAD software, engineers and designers were able to quickly and easily generate and modify drawings. Design firms could hire fewer staff, and both design and product development cycles were greatly reduced. CAD software also allowed engineers and designers to generate their own drawings, rather than to attempt to explain them to a draftsman, resulting in more accurate design.

Though CAD drawings have been in use since the 1960s, it wasn’t until the late 1980s and early 1990s that CAD software became a cost-effective option for many industries. Early versions of the software relied on 2D vector design, while modern CAD drawings include 3D modeling capabilities. Today’s modeling software allows designers to not only draw an object, but to rotate it on an axis, and to see through the object’s walls from the inside. This modeling capability is particularly useful in construction and engineering, allowing designers to virtually “walk-through” a structure and explore different angles.

Most CAD software is designed only for Windows or Linux operating systems. Complex CAD drawings may require advanced graphics cards and high levels of random access memory (RAM), but simpler drawings can be done on almost any basic computer. CAD software is operated using a traditional mouse, though some professional designers may supplement this operation using a digital pen or drawing tablet.

AUTOCAD 2D & 3D

August 23, 2011

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.

01-autocad-freestyle-software-preview

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.
