The main function of the application is that of converting between various file formats. The PDF Export (or convert) tool is the first one you come across because it's placed in the File menu and has a very intuitive interface. 

The batch conversion can be done from and to multiple file formats and it allows you to select the desired target file, page layout and background color. 

These are the default pen sets offered by ACME CADConverter with multiple choices for the user that are not limited only to the color of the pen. 

With this application you can also perform an operation such as the font replacing in the folders you select.
