    The applications of the CAD software have been increasing in the last few years or so, hence their popularity has been increasing. The CAD software helps in increasing the productivity of the designer, and reduce designing time, cost, and project completion time. There are number of other advantages offered by the CAD software.

    Most of the CAD software are very expensive. For instance, one of the most popular CAD software, AutoCAD 2009, costs more than $3000. For a number of engineering designing professionals and firms this can be a major cost to incur. Fortunately, now a number of free CAD software are also available on Internet. To download and install free CAD software you don’t have to pay anything. Though these software may not be as advanced as the costlier ones, they have a number of features that are good enough for a number of designing professionals and firms.
