The results of your drawing efforts might be used for marketing tools, logos and just about anything you might imagine that will ultimately be used to communicate an idea or concept. As of Version 7 of CorelDRAW you can also produce work that can be published for use on the World Wide Web.
Vectors are the mathmatical relationships that governs how the tools in Draw are used.
The developers of Draw intended that you identify where the curves are in relationship to their connecting points which are made up from nodes. This illustrates the fundamental way that the software is to be used. EPS, WMF and CGM files are some examples of vector art instruction file formats. Bitmap images are only a bunch of pixels working together to emulate a suggested design and they do not know what shape they will equal. CorelDRAW is used to create shapes.
