CAD's Introduction in English: Part One
Introduction:
CAD, which stands for Computer-Aided Design, is a revolutionary technology that has transformed the field of design and engineering. It allows designers and engineers to create precise and detailed 2D and 3D digital models of products, buildings, and other objects. CAD software has become an indispensable tool in various industries, including architecture, automotive, aerospace, and manufacturing.
Benefits of CAD:
1. Enhanced Precision and Accuracy: CAD software enables designers to create highly accurate and precise models. The use of mathematical algorithms ensures that measurements and dimensions are exact, reducing errors and minimizing the need for rework. This enhanced precision translates into better quality products and increased efficiency.
2. Improved Productivity: CAD software significantly improves the productivity of designers and engineers. It automates repetitive tasks, such as creating multiple copies of a design or modifying dimensions. Additionally, CAD software allows for easy collaboration and sharing of design files, enabling multiple team members to work on a project simultaneously.
3. Time and Cost Savings: CAD software expedites the design process and reduces the time required to bring a product to market. With CAD, designers can quickly iterate and modify designs, eliminating the need for manual redrawing. This not only saves time but also reduces material waste and costs associated with physical prototyping.
4. Visualization and Simulation: CAD software offers powerful visualization and simulation capabilities. Designers can create realistic 3D models, allowing them to visualize the final product before it is manufactured. Additionally, CAD software enables engineers to simulate the performance and behavior of a design under various conditions, helping to identify and address potential issues early in the design process.
5. Design Optimization: CAD software provides tools for optimizing designs. Designers can analyze different parameters, such as material selection, weight distribution, and structural integrity, to optimize the performance and efficiency of a design. This iterative process allows for continuous improvement and innovation.
CAD Applications:
CAD software finds applications in various industries. In architecture, CAD is used to create detailed building plans and renderings. In the automotive industry, designers use CAD to develop car models and perform simulations for crash tests and aerodynamics. In aerospace, CAD is used to design aircraft and spacecraft, ensuring safety and efficiency. In manufacturing, CAD is used to create 3D models of products and generate manufacturing instructions.
Conclusion:
CAD has revolutionized the design and engineering landscape, providing designers and engineers with powerful tools to create precise and detailed digital models. The benefits of CAD, including enhanced precision, improved productivity, time and cost savings, visualization and simulation capabilities, and design optimization, make it an indispensable tool in various industries. CAD's ability to streamline the design process and enable innovation has made it an essential technology for the modern world. Stay tuned for the second part of our CAD introduction to explore more about this incredible technology.
CAD的英文介绍 篇三
CAD的英文介绍|什么是CAD|CAD的英文全称Computer-assisted dispatch
Computer-assisted dispatch (also called CAD) is a method of dispatching taxicabs, couriers, field service technicians, or emergency services by computer. It can either be used to send messages to the dispatchee via a mobile data terminal (also called an MDT) and/or used to store and retrieve data (i.e. Radio Logs, Field Interviews, Client Information, Schedules, etc.)
Computer assisted dispatch systems use one or more servers located in a central dispatch office, which communicate with mobile data terminals installed in the remote vehicles. There are a multitude of CAD Programs that suit different department needs, but the layout of each system is the same. The purpose of CAD in the first place is to quicken the information that is received or transmitted from the call-taker or dispatcher to those who will facilitate the original call.
In an ideal setting, a call is received by a call-taker and information about the call is inputted into the CAD template. Generally, Location, Reporting Party and Incident are the main the fields that have to be populated by type-codes. For example, if there was a Burglary in progress, the type-code for that Incident could be BURG; when BURG is typed out, then the Program will spell out BURGLARY (in progress). If the Location was at the 1400 block of Madison, the type-code could be 14MAD. The Reporting Party information would be populated by the call-taker including Last Name, First Name, Call-Back number, etc.
A typical CAD Printout look something like this based on the examples above:
LOCATION - 1400 Madison RP - Doe, John, 555-5555 INCIDENT - BURGLARY (in progress)
Again, granted as it can be seen that the fields are spelled out, the call-taker uses those abbreviations that are already predetermined in order to quickly gather and transmit the information.
The Dispatcher then receives the call from the call-taker and is able dispatch the call to those available. The Dispatcher's screen would show the available personnel that are dispatchable. A typical setting can be exemplified by this:
--------------------------------------------------------------------------------
INCIDENT # - 554123 LOCATION - 1400 Madison RP - Doe, John, 555-5555 INCIDENT - BURGLARY (In Progress)
--------------------------------------------------------------------------------
Units available - (3) Units out of service - (2)
745 - Avail. 746 - Not Avail. Inc # 554121 747 - Avail. 748 - Avail. 749 - Not Avail. Inc # 554122
--------------------------------------------------------------------------------
Everything that is gathered, dispatched and disposed is usually stored in a central server where the type codes reside in, or possibly another server. All of these calls which have incident numbers attached to them can be recalled by an internal search engine. For example, a request for a printout of all calls to Madison in the past hour could be gathered by querying the CAD Program by Location:
Search by: Location LOCATION [ ] —— Result:
(Now filled in)
Search by: Location LOCATION [14MAD ] —— Result: (1) Incidents
CAD can be used in a multitude of ways, whether it is for Radio Logs, Call Logs or Statistical Analysis.
Computerized mapping, GPS, and caller-identification technology are often used to enhance the service by pinpointing the locations of both the client and the most suitable vehicle for serving the client.
