One huge advantage that SolidWorks has over most CAD software is the ability to open nearly every CAD file type on the market today. Its automatic translation tools allow you to convert 2D drawings or 3D solids into SolidWorks, quickly define them, and then use them for your own purposes. This ability can save a lot of time and give you an advantage over your competition in that you don't have to ask your customer to provide data in a specific format to be able to use it.
SolidWorks 2011 features built-in translators that let you exchange CAD data created in a wide variety of software applications and file formats. Below is a list of the file types that SolidWorks can open:
