AutoCAD is one of the main Computer Aided Design (CAD) software tools used for technical drawing in the construction industry. It was first released in 1982 and is used to produce drawings for design, construction, maintenance and operation as well as for future work to the structure.
The UK nbs National BIM Survey 2013 suggested that the most popular CAD software amongst respondents was:
AutoCAD drawings are created at 'full size' and can then be scaled to suit different paper sizesor other media. It is mainly used to produce 2D drawaings, although there is also a 3D feature
AutoCAD works by using a limited number of tools to draw straight lines, circles, arc's, and so on which are saved as a series of points or coordinates. This means that the resulting drawingfiles are relatively small in size.
As the drawing progresses other tools can be used to make the drawing more complex and contain more information. This full size drawing is drawn in model space mode which is virtually unlimited (in reality limited by the computer hardware specification), and then scaled down in the paper [space] mode.
The native file format for AutoCAD is .dwg, but files can also be produced in an interchange file format DXF. Averti have a adopted an annual release strategy now popular for many software productsas it allows a revenue stream for the programmers and ensures development of the software.
In AutoCAD 2010 it adopted the new visual style developed by Microsoft to allow use by all devices such as touchscreens, mouse, pens and digitizers.
