You have spent a lot of time and money developing and perfecting your 2D files.  How easy would it be to move to 3D? You obviously do not want to start from scratch. That would be completely ridiculous. The transition process is made of a whole lot more than simply purchasing new software.  With this software, however, users of Solidworks in Illinois can keep using their current files.  The software has a feature called DWGeditor, which is extremely useful. It allows users of Solidworks in Illinois and users of Solidworks in Colorado to create 3D CAD files from your DWG files.  The best part?  You can read and edit them too.   By simplifying your design process, your company or business is able to focus on what really matters: your designs, not the software.
