What is a .PD file?
A .PD file is a special type of document created with FlexiSIGN 5, which is a professional tool used for designing, printing, and cutting out signs. This file holds the design of a sign in what's called a vector graphic format. This means that no matter how much you enlarge or shrink the image, it will not lose its quality. Besides vector graphics, .PD files can also include images (known as raster graphics) and text.
To open a .PD file, you would typically use the SAi Flexi software, or the SAi Flexi More Information program. These programs are specifically designed to work with .PD files, allowing you to view and edit the sign designs.
Additionally, it's interesting to note that .PD files are not only used in sign making. They are also used in the world of music and gaming. For example, Pure Data is a visual programming language that lets developers create interactive computer music. Electronic Arts, a big name in the gaming industry, has adapted Pure Data into their own version called EAPd for their game Spore. In this context, .PD files are used to manage the in-game music, showing the versatility of this file type beyond just sign making.
