A viewport is a polygon viewing region in computer graphics. In computer graphics theory, there are two region-like notions of relevance when rendering some objects to an image. In textbook terminology, the world coordinate window is the area of interest (meaning what the user wants to visualize) in some application-specific coordinates, e.g ...

AutoCAD DXF (Drawing Interchange Format, or Drawing Exchange Format) is a computer-aided design (CAD) data file format developed by Autodesk [2] to enable CAD data exchange and interoperability between AutoCAD on different computing platforms.
Image compression is a type of data compression applied to digital images, to reduce their cost for storage or transmission. Algorithms may take advantage of visual perception and the statistical properties of image data to provide superior results compared with generic data compression methods which are used for other digital data.
A 3D projection (or graphical projection) is a design technique used to display a three-dimensional (3D) object on a two-dimensional (2D) surface. These projections rely on visual perspective and aspect analysis to project a complex object for viewing capability on a simpler plane.
Checkers, software that analyze CAD data formats, are often employed before and after data translation. The checkers can check the organization and quality of the data against internal company standards and international or industry standards. These checkers can be built into specific CAD packages or work on a number of CAD file formats.
