No, the Pipe2CAD application won't work with AutoCAD 2014 and Windows 7. If you try to visit the official website at the following address http://www.pipe2cad.com/ , you will see that a generic page will load meaning the software has been discontinued. In this case, there is nothing you can do except using an alternative, but since there isn't one available, I recommend checking the database of Software Informer to look for the available CAD applications.
