What is a composite or bridge entity in database terms and when is it used?
it is an entity whose primary key is composed of the combination of the primary keys of the entities that must be linked. It is used in linking tables of the M:N relationship that needs to be converted into two 1:M relationship for your database
What is a role of a DWG?
DWG (from drawing) is a binary file format used for storing two- and three- dimensional design data and metadata. It is the native format for several CAD packages including DraftSight, AutoCAD, IntelliCAD (and its variants) and Caddie.Some third party vendor provide free file viewer, such as AIGraph CAD Viewer.
Where can you get cad training?
There are several options available for your mother. Many cad training programs can be completed online at a great conviencence. I would highly suggest the following: www.caddtrain.com/ .

What are CAD drawings?
CAD drawings are digital technical drawings created using Computer-Aided Design (CAD) software. These drawings represent architectural, engineering, and mechanical designs with precise dimensions, annotations, and details. CAD drawings are widely used in construction, manufacturing, and design industries to create 2D and 3D models of structures, components, and systems. Key Benefits of CAD Drawings: High Precision – Ensures accurate measurements and design consistency. Easy Modifications – Allows quick edits and revisions without redrawing everything manually. Enhanced Collaboration – Enables multiple professionals to work on the same project digitally. Improved Visualization – Supports 3D modeling for better design interpretation. Time and Cost Efficiency – Reduces errors and speeds up the drafting process. Popular CAD software includes AutoCAD, Revit, SolidWorks, SketchUp, and MicroStation, helping professionals design and execute projects efficiently.
What is a CAD database?
A CAD database is a structured repository that stores computer-aided design (CAD) data, including 2D and 3D models, drawings, and metadata related to design projects. It enables efficient organization, retrieval, and management of design information, facilitating collaboration among multiple users and teams. CAD databases often integrate with CAD software to streamline workflows and maintain version control, ensuring that all stakeholders access the most current design files.

What is cad-welding?
CAD welding is named after Dr Cadwell. It is a form of thermite welding used to bond wire to metal, typically used in the rail industry.
What drawing program is used for cad?

Cad graphic files are stored which file?
It depends on the software used to write the CAD file.
Is a CAD drafter used in design?
Yes. CAD stands for Computer aided designs. Its a program used to help make designs for all types of draft work. Most CAD workers are required to have a degree
What are the advantages of autocad over manual drafting?
Three Dimensional Modeling: Creating 3D models manually is a very difficult and tiresome job. 3D CAD packages have many more powerful features for creating the 3D models easily.Easy to Modify: Modifying the CAD geometry is easy; you will always have "copy", "cut", "paste", "delete", "move" or some similar editing options available with each of the packages.Easy to Reproduce: Draftsmen used to take days to complete a drawing by manual drafting, and reproducing the drawing meant recreating the drawing from the beginning. But, in case of the CAD, you can reproduce the drawing in no time and make as many copies as you want.Computer Aided Manufacturing (CAM): The 3D CAD geometry is used as input for the CAM packages for generating NC codes. The manual drawings cannot be used for CAM packages.Computer Aided Engineering (CAE): The 3D CAD geometry is used as input for the CAE packages. The CAE packages can simulate the loading conditions and tell whether the CAD geometry can withstand the real loading or not. The drawings created manually cannot be used for CAE.Simulation of the Mechanisms: The 3D CAD geometry can be used for simulating the mechanism, thus you can check the functionality of a machine without investing in prototype building. Manual drawings cannot be used for mechanism simulation.Database Creation: The CAD files can be used to create a PDM/PLM database. Once created, the CAD database can be accessed through a wide area network. The drawings created by manual drafting can only be stored locally.Logical: CAD models or geometry entities are logically connected, or in other words you cannot create a CAD model which is not possible practically. The drawings created by the manual drafting method do not have such checks, and you can create anything.Environment Friendly: Manual drawings are necessarily created on paper, but the CAD drawings can be stored and used electronically without using paper.Access Control: Some of the drawings and design documents are very crucial for a company's business, and such drawings should not be accessible to all. Providing access controls of such drawings are easy for the CAD drawings, and the access level can be defined for each CAD drawings. Strict access control and maintaining confidentiality is difficult for the manual drawings.
