CAD framework techniques have been used extensively as the software ``glue'' that can turn a collection of individual tools into an effective and user-friendly integrated engineering environment.
Processing CAD Data to Features
DWG and DXF files have a very limited structure for handling semantic infomration -- for example the relationship between room numbers and room polygons, for example.
CAD
CAD systems evolved to create designs and plans of buildings and infrastructure. This activity required that components of fixed characteristics be assembled to create the whole structure.
CAD or CADD refers to computer-aided design and drafting. CAD systems are used to create maps and plans and are closely related to GIS systems.
CAD: Computer Aided Design. An automated system for the design, drafting and display of graphically oriented information
cadastre: Public record of the extent, value and ownership of land within a district for purposes of taxation.
CAD
Computer Aided Design. The design activities, including drafting and illustrating, in which information processing systems are used to carry out functions such as designing or improving a part or a product. (Walker 1993).

CAD/CADD - (computers) Computer-Aided Design/ Computer-Aided Design and Drafting. Any system for Computer-Aided rather than manual drafting and design. Displays data spatially.
CAD See computer-aided design or drafting.
Cadastre A record of interests in land, encompassing both the nature and extent of interests.
CAD: Computer Aided Design. An automated process for interactively creating, modifying and manipulating spatial information. Mathematical integrity of the spatial model is adequate to support legal survey and engineering design requirements.

CAD software is commonly available and can produce results from basic survey plots to finished map sheets. Such drafting tools offer surveyors more accuracy, efficiency, flexibility, and quality in the production of hard-copy plots.
CAD - Computer Aided Design: Software packages designed for high quality graphical output regarding the design of products. Automated functions allow for easy and fast output that can be utilized by a novice user as well as the specialist.
These systems usually are enhancements to computer-aided drafting (CAD) software and provide powerful tools for making and updating maps.
A raster image is actually not layered at all like a vector image in a CAD drawing. On the contrary, all the information is agglomerated together into an unhelpful (for our purpose) mess.
The most common method of data creation is digitization, where a hard copy map or survey plan is transferred into a digital medium through the use of a computer-aided design (CAD) program, and geo-referencing capabilities.
By integrating GIS, Computer Aided Design (CAD) and Global Positioning Systems (GPS), using high-end GIS Mapping and GIS data conversions softwares, our GIS Services assist our customers in producing maps including contour maps, spatial maps, ...
The major difference between GIS software and CAD mapping software is the provision of capabilities for transforming the original spatial data in order to be able to answer particular queries.
The corporation has a long history of developing 'GIS/CAD' products for technical, engineering, and industry based applications.
For example, the GIS (or CAD) operator will trace the boundary of each state with a digitizing tablet or mouse. Boundaries common to pairs of states will therefore be traced twice.
GIS data used in the model can be raster, vector, textual and hybrid types from many diverse sources using state-of-the-art techniques: geometry from CAD systems; video and slide images; commercially available digital data (vector and/or raster); ...
Computer Aided Design (CAD)
Software with the capability of assisting the operator to perform standard engineering and architecture design functions. Examples of CAD software include AutoCad, and Intergraph Microstation.
The unrectified (scanned/CAD etc.) map is imported into a XY location. Then start GRASS with the location/mapset where you want the georectified map to END UP (i.e., the projected TARGET location).
Drawing Exchange Format (DXF)
An exchange format for CAD files. A format for storing vector data in ASCII or binary files; used by AutoCAD and other CAD software and convertible to ARC/INFO coverages.
