Both 3-D graphics and CAD (computer-aided design) technology rely heavily on vector graphics. It provides graphic designers with the ability to create precise, scalable and layered images. Vector graphics drawing software is used for creating and editing vector graphics.

You may want to take a look at related articles: In other words, vector graphics are resolution-independent and thus can remain the highest quality at any scale. Raster images are based on pixels and thus scale with loss of clarity, while vector-based images can be scaled indefinitely without degrading. The former is the representation of images as an array of pixlels, and the latter uses paths, points, lines, curves and shapes or polygons (which are all based upon mathematical equations) for the same purpose. Node editing: moving nodes and Bezier handles, node alignment and distribution, etc.In computer graphics images can be represented in two ways - using raster graphics (or bitmap) or vector graphics. Path markers (ending, middle and/or beginning marks, e.g. 
Dashed strokes, with many predefined dash patterns. A gradient editor capable of multi-stop gradients. Color selector (RGB, HSL, CMYK, color wheel, CMS). Layers (lock and/or hide individual layers, rearrange them, etc layers can form a hierarchical tree). Grouping objects ("select in group" without ungrouping, or "enter the group" making it a temporary layer). Z-order operations (raising and lowering). Transformations (moving, scaling, rotating, skewing), both interactively and by specifying exact numeric values. 
Clones ("live" linked copies of objects), including a tool to create patterns and arrangements of clones. 
Embedded bitmaps (with a command to create and embed bitmaps of selected objects). Text tool (multi-line text, full on-canvas editing). Shape tools: rectangles (may have rounded corners), ellipses (includes circles, arcs, segments), stars/polygons (can be rounded and/or randomized), spirals. 
Drawing: pencil tool (freehand drawing with simple paths), pen tool (creating Bézier curves and straight lines), calligraphy tool (freehand drawing using filled paths representing calligraphic strokes).
