Marketing Directors Email Lists


There are numerous advantages of computer-aided design, just certain of these can be easily quantified. Certain benefits are not tangible and can be seen in higher quality of work and more relevant and useful information.

Marketing Directors email lists
Marketing Directors email lists

Certain advantages are tangible and are described below.

1. Improvement in productivity of design: CAD helps in increased design efficiency by reducing the time needed to create conceptual designs, analysis, and drawing. It also allows you to cut down on the number of people required for a specific project. Improvement in productivity in the computer-aided design processes is contingent upon aspects like

Complexity of drawing

The degree of repetition of features on the created parts. Asymmetry of the components

A wide range of library of user-defined shapes and common entities

2. Faster lead times Interactive CAD is more efficient than manual design processes. Marketing Directors email lists. Tools for CAD reduce the number of times iterations. They make it easier to complete the job of creating reports and bill of materials by using the CAD system. A complete set of components and documents can be completed in a short amount of time. The shorter lead times for design will result in a reduction of length of time between the reception of an order from the customer to the completion of the product. The increased productivity of designers working in the CAD environment can reduce the importance of engineering analysis, design and drafting as crucial components of the overall lead time of manufacturing.

3. Design analysis The design analysis tools that are available in CAD systems aid in optimizing the design and create an optimal functional work pattern. Utilizing design analysis software like finite element analysis as well as Kinematics analysis can reduce the duration of the analysis and enhances the accuracy of the design. Instead of having discussions between the design and analysis teams designers are able to perform the analysis while using the CAD computer. This can increase the concentration of designers as the analysis is an interactive process and calculations of properties related to mass can be done nearly instantly. Buy Marketing Directors email lists online.

4. Less design mistakes Interactive CAD systems are equipped with built-in capabilities to prevent mistakes when designing, drawing, and documentation. These errors occur during manual handling. The errors are prevented because interactive CAD systems can perform routine and time-consuming functions like multiple symbol placements,
5. Design flexibility Interactive CAD systems apart from creating designs that have repeated accuracy has the benefit of allowing design modifications to meet customer’s requirements.

6. Standardization of drafting, design and documenting: A one operating system and database that is that is used in CAD provides a common foundation for analysis, design and drafting using interactive CAD software, drawings are “standardized” because they’re drawn. It’s also possible to reuse modules from previous versions to create a variety of products. Buy Marketing Directors email lists online.

7. Drawings are easier to comprehend: Thanks to the increasing utilization of 3-D images and modeling it is now easier to understand the characteristics of the part easily. It is not necessary to mentally reconstruct the exact shape of the objects. A lot of software programs permit 3D views from an existing 2D model. This offers several advantages from a manufacturing standpoint.

Marketing Directors email address lists

8. Improved procedures for engineering modifications Control and implementation of changes to engineering can be greatly improved by using computer-aided design.

Marketing Directors email address lists
Marketing Directors email address lists

Original drawings and reports are saved inside the databases used by the computer-aided design system and are easily accessible. Revisions can be saved as well as new drawings with modifications can be made without damaging the previous features.

9. Manufacturing benefits Benefits of computer designed designs can be used as the base for many downstream manufacturing processes. A few of the benefits for manufacturing are:
(a) Design of fixtures and tools to manufacture
(b) Computer-aided process plan
(c) Computer-aided inspection

(d) Formulation of numerical control programming for the production of components on computer machines for numerical control

(e) (e) Preparation of assembly lists and bills of materials needed for production
(f) Classification and coding of elements
(g) Production Control and planning
(h) Assembly sequence planning


Hardware components used in computer-aided designs are offered in range in sizes, designs, and capabilities. Buy Marketing Directors email address lists online. This means that you can choose the CAD system that best meets the specific requirements for graphics and computation of the company that uses it. Engineering firms that aren’t involved in manufacturing would opt for an exclusive system for drawing and design-related tasks. Manufacturing companies will choose the system as integrated into a larger CAD/CAM system.

Modem CAD systems are built upon interactivity computer graphics (lCG). However, the CAD scope also includes other computer systems too. For instance computer-aided design has been carried out in batch mode instead of in an interactivity mode. Interactive graphics gives immediate responses to inputs made by the user. Buy Marketing Directors email address lists online. The both the user is in constant interaction with one another. The user can input commands and is able to respond to queries generated from the computer. It is currently restricted to CAD systems that use interactive computer graphics.Typically the standalone CAD system will comprise some of the hardware parts listed below:

Graphics terminal Operator output devices
Devices for operator input Secondary storage
Central Processing Unit (CPU)

Marketing Directors email id lists

DESIGN Workstation

The CAD workstation acts as the interface between the system and the external world. It plays a significant role in determining how easy and effective it can be for designers to utilize an CAD program.

Marketing Directors email id lists
Marketing Directors email id lists

The workstation should fulfill five essential functions:
1. It has to interface directly with the central processing unit.
2. It should create a stable visual image for the user.
3. It should include details of graphic images in digital format.
4. It is responsible for translating computer commands into operation functions.
5. It should allow for interaction between the user and the system. Buy Marketing Directors email id lists online.

Interactive graphics has been proven to be the best method to fulfill these tasks. An average interactive graphic system would comprise these hardware elements:
Graphics terminal
Operator input devices


There are a variety of approaches that have been employed in the creation of graphics terminals. Technology continues to improve the quality of their products, and also lower their prices.

(I) Image Generation in Computer Graphics

The majority of computer graphics terminals that are used today utilize the cathode tube (CRT) as the display device. Buy Marketing Directors email id lists online. 

Television sets make use of a version similar to that of the picture tube. The CRT’s operation is illustrated in the figure 2.4. A cathode that is heated emits a high-speed electron beam onto a glass coated with phosphor screen. The electrons in the beam energize the phosphor coating, causing it to shine at locations where the beam comes into contact with the. By using the electron beam to focus altering its intensity and adjusting the area of contact with the phosphor coating by the use of a deflector that allows the beam to be used to create an image of the screen on the CRT. Buy Marketing Directors email id lists online.

There are two main methods that are used by modern computer graphics terminals to generate images for your CRT’s screen. These are:

1. Stroke writing
2. Scans of the Raster

Other terms used to describe stroke writing include lines drawing, random positioning vector writing, directed beam. Other terms for the raster scan technique are the term digital TV as well as scan graphics.

Marketing Directors email id directory

The stroke writing system employs an electron beam that functions similar to a pencil in order to produce lines that appears on the LCD.

Marketing Directors email id directory

The image is composed of of straight lines. The line segments are drawn onto the screen by controlling the beam’s motion from one location in the display to another. each point is identified by its coordinates x and y.

While the process produces images made up of only straight lines smooth curves can be created by having the line segments as short as possible. When using the raster scan method the screen for viewing is divided i.nto many distinct phosphor image elements, referred to as pixels. This matrix makes up the raster. The number of distinct pixels on the display can vary from 256×256 to 1024 10-24 (a total of more than 65,000 to one million points). Every pixel of the screen can be lit with different brightness. Colour screens permit the pixels to be able to display different shades and also the brightness. Buy Marketing Directors email id directory online.

In operation, an electron beam generates the image by sweeping across an horizontal line on the monitor from the left side to the right, and activating the pixels on the area of the sweep at the time that an entire sweep has completed. The electron beam is then moved across the lines below , and continues in a fixed pattern as illustrated on Figure 2.6. After the screen is swept the process continues at a speed of 30-60 complete screens per second.

(II) Graphics Terminals

The two methods described previously are the most common methods used in the production of modern CAD graphics terminals. There is also a range of other technical aspects that create different kinds and models of graphics devices. This includes the kind of phosphor coating applied to the screen, the required colour is needed as well as the pixel density, in addition to the size of memory to produce the image. The three kinds of graphics terminals are:

(a) Directed beam refresh tube (DBRT)
(b) Direct storage tube with view (DVST)
(c) Terminals for scanning with a scanner (Digital TV)

(a) directed Beam Refresh Tube (DBRT)

Direct beam’s refresh device employs stroke writing to produce the image displayed that is displayed on the screen of CRT.  Buy Marketing Directors email id directory online. 

The term “refresh” in its title refers to the fact that the image needs to be recreated several times in a second to minimize the visible flickering on the screen. The phosphor elements of the screen can maintain their brightness for the duration of. To enable the image to remain this picture tube must be refreshed. This is accomplished by making the directed beam repeat the image when viewed on screens with a high density (very precise lines or a lot of characters in text). It can be difficult to prevent flickering with this method. Buy Marketing Directors email id directory online.

There are many advantages with targeted beam refresh technology. Because the image is continuously refreshed, selective erasure and modification of the image can be easy to accomplish. Additionally, you can offer animated images using refresh rube.

Marketing Directors email id outlook

This directed beam technology is the oldest of modern graphics display technology. Other names used to describe this system include vector refresh , and stroke-writing refresh.

The first refresh tubes were expensive, but the consistently falling cost of solid-state circuitry has brought the cost of these systems to a level that is in line with other kinds.

(b) Direct View Storage Tube (DVST)

The DVST terminals also employ stroke writing to create the image that is displayed of the screen.The term “storage tube” refers to the capacity for the CRT screen’s display to store the image that has been projected onto it, thereby eliminating the necessity of rewriting the image constantly.What can make this happen is using an electron flood gun that is directed towards the screen coated with phosphor that ensures that the phosphor elements are illuminated when they are energized by the writing electron beam. The image that is projected onto the CRT screen will not flicker. 

Lines can be easily included in the picture with no being concerned about their impact on the image’s the density or refresh rate. The drawback to the storage tube’s use is the individual lines are not able to be eliminated from an image. Buy Marketing Directors email id outlook online.

Storage tubes are most affordable terminals, and are able to display massive amounts of data, whether in text or graphic form. Because of these attributes, there is a good chance that there will be greater storage tube devices available in the service industries. The main drawback of the storage CRT is the fact that selective erasure isn’t available if the user wishes to alter the image. The changes won’t be visible upon the monitor until the complete image is rebuilt. Other drawbacks include the absence of a colour-capable device and the inability to use an electronic light pen to act as a device for data entry and the lack of animation capabilities.

(c) Raster Scan Terminals (Digital TV)

The terminals for raster scan work by the use of an electron beam to trace a zigzag line across the screen. Its operation is comparable to that of a television set. The main difference is that a TV set makes use of analog signals produced by a video camera to produce the image displayed on the CRT screen. However, the ICG terminal, which is a raster scan ICG terminal utilizes digital signals created by computers. This is why raster scanner terminals utilized in computer graphics are often called digital TVs. Buy Marketing Directors email id outlook online.

It was the first time that a raster scanner graphics terminal with refresh tubes was restricted by the expense of memory in computers. For instance, the most simple and least expensive terminal that falls into this category has just two levels of beam intensities: ON and off. This means that every image pixel is either lit or dark. A picture tube that has resolution of 256 lines and the ability to address 256 points per line for the picture will require 256 x 256 or more than 65,000 bits of storage. The memory stores the ON/OFF status of the image pixel in the screen of the CRT. This memory is known as”the frame buffer,” also known as a refresh buffer. Buy Marketing Directors email id outlook online.

The quality of images can be improved through increasing the density of the pixels, or by adding the gray scale (or color). The increase in pixel density for the same screen size is the result of the addition of additional lines with a higher resolution as well as greater number of addressable lines per line. A 1024×1024 raster display would have more than 1 million bits memory inside the frame buffer. Gray scales are achieved by increasing the number of levels of intensity, which are displayed at every pixel in order to record levels of intensity. Buy Marketing Directors email id outlook online.

Two bits are needed in order to show four levels. and three bits for eight levels, and the list goes on. Six or five bits will be required to get an approximate representation of a gray scale. A color display requires three times the number of bits are needed to obtain various levels of intensity for the three primary colours, namely red blue, green and. A raster-scan graphics terminal that has a high resolution and gray scale may require a large memory refresh buffer. Before recent advances in memory technology, price of this storage capacity was expensive for a terminal that had high-quality images.

The ability to create color and animation was impossible unless you had extremely low resolutions.

Marketing Directors email id database

Today, it is possible to build digital TV systems to display interactive computer graphics for a price that are competitive with the other two kinds. The advantages of current scanners for raster scanning include the ability to use television monitors that are low-cost with colour capabilities, as well as the possibility of animating the image.


Input devices for graphics are installed on the graphics workstation in order to allow for a more efficient interaction between users and systems. Workstations typically have a variety of input devices, allowing users to choose from different input functions that are pre-programmed. These functions allow the user to design or alter images on the CRT screen , or enter data in alphanumeric format in the software. This creates a full portion of the screen and the complete description of the piece within the CAD database. Buy Marketing Directors email id database online.

Different CAD systems vendors provide various kinds of (graphics) input devices for operators.
These devices are categorized into three categories:
(a) Cursor control devices
(b) Digitizers
(c) Alphanumeric and other keyboard terminals

Digitalizers and Cursor control devices can be used both for graphic interface with the systems. Keyboard terminals can be used as input devices to input commands as well as numerical data. There are two primary types of graphical interactions that can be performed through digitally controlling the cursor and placing new items onto the LCD screen. By pointing or otherwise indicating areas on the screen, generally associated with images, a graphical input device is able to lend itself to both functions. It is however difficult to achieve with just one device and this is the reason why many workstations are equipped with various input options. Buy Marketing Directors email id database online.

(a) Cursor Control Devices

The cursor is manually taken in the form of a bright area on the CRT screen which signifies where the drawing or writing will take place. The computer can detect the current location on the screen of the cursor. This means that the ability of the user to control the cursor’s position permits locational information to be added to the database of the CAD system. An example of this would be the user’s ability to locate the cursor in order to determine the point at which a line begins. line. A more sophisticated scenario could be to place the cursor in a specific position to choose an item from a list of functions that are which are displayed by the monitor. Buy Marketing Directors email id database online.

Four of the items on the list let you control the cursor, but without physical contact with an LCD screen from the users. The two last devices on the list require users to manage the cursor by pressing the screen using the pen-like device.

Marketing Directors email leads

The thumb wheel uses two thumb wheels, one to control the horizontal location of the cursor, and the one that controls the vertical direction of the cursor.

Marketing Directors email leads

This kind of device is typically installed as an integral component that of the terminal for CRT. The cursor on this configuration is usually shown as an intersecting of the vertical line with an horizontal line that is which is shown on the screen of the CRT. These two lines are similar to cross hairs of gun sights that extend across the length and width that the display.

The keys for direction that are on the keyboards represent a different fundamental method of controlling cursors not just for graphic terminals, but also for CRT terminals that do not have graphics capabilities. Four keys are utilized to control the four directions that the cursor is able to move (right or left and also up and downwards).

The joystick is shown on Figure 2.7. It is comprised of a rectangular box that is equipped with a vertical stick that is pushed in any direction, causing the cursor to move in the direction it is pointing. The name “joystick” comes by reference to the controls stick utilized in older aircrafts. Buy Marketing Directors email leads online.

The tracker ball can be seen in figure 2.7. Its mechanism is identical to the joystick, except that the operator controlled ball is turned by the operator to shift the cursor into the direction desired in the display.

A light pen can be described as a pointing instrument in which the computer tries to determine the location where the pen comes into contact with the monitor. Contrary to what the name implies, the light pen doesn’t emit light. Instead , it acts as the detector of light that is placed on the CRT’s screen. It utilizes a photodiode or phototransistor or other type or type of sensor for light. The light pen is used with a refresh type CRT, but not with storage tubes. This is due to the fact that the image inside the tube that refreshes is produced in a time-sequence. Its time sequence is brief that the picture appears to be continuous to the human eye. Buy Marketing Directors email leads online.

But, the computer can discern the timing sequence and aligns this time with the pen’s position in relation to the monitor. The computer is acting the role of an optical loop that can find the cursor, or to carry out a different input function.

The pen and tablet in computer graphics are the use of an electronic tablet together with the electronic pen. Tablets are flat, smooth surface distinct from the CRT screen , on which the user can draw using stylus-like pen to input commands or control the cursor. It is worth noting that the direction keys on thumb wheels tracker balls, joysticks and joysticks tend to be restricted in their use to control cursor movement. Buy Marketing Directors email leads online.

The pen/tablet light and the tablet are commonly used for different input functions, including cursor control. A few of these functions include:

* Selecting from a menu menu.

Draw on screen or drawing strokes on the tablet or the screen that show the image that is being drawn.

Marketing Directors mailing lists

* Selecting a specific portion of the screen to be enlarged of an image that is already present,

A light pen is similar to a fountain pen in its method of holding it, however, it is based on the principle of light instead of ink, hence its name.

Marketing Directors mailing lists
Marketing Directors mailing lists

Light pens do not function to write on screens which is a misconception among many however, they’re actually designed for detecting the existence of light on the screen , as illustrated in Figure 2.8 using the help of a resistor that detects light. 

Their primary use in graphic programs is to detect objects or areas on the screen to allow for the possible handling of graphics. They can be used only on refresh-type display devices. Light pen resolution is not great since the view field of the photosensitive device is conical. Since the light pen is pointing directly at the display it’s an ideal tool for graphic interaction. But, since the user is required to keep the pen in place against gravity and its cable to connect the adapter card to the graphics display for making any choice ergonomically, it’s not ideal to use for extended time periods. Buy Marketing Directors mailing lists online.

The mouse in figure 2.7 is the pointing device, and has gained importance since the introduction of microprocessors as well as the pull-down menus that come with software applications. The mouse operates on three basic principles-Mechanical, Optical and Opto- mechanical. The mechanical mouse is an unrestricted floating ball coated with rubber on the underside that, when placed on a flat surface, can follow the movements that the user’s hand makes. The ball’s movement is reconstructed into x and y movements through two rollers that are pressed into the ball. They then direct the cursor’s position on the screen. It is then used to perform any of the applications you desire by way of clicking button on your mouse.

It is only able to indicate the screen, but it is not capable of giving information about the position. For optical mouse transparent plain surface that has fine grids etched on it is needed. The LEDs inside of the device (in instead of the ball) will reflect the number of grid lines that cross the tile in x and y directions, thus displaying the distance traveled.  Buy Marketing Directors mailing lists online. 

The lifespan of an optical mouse is very long since there are no moving parts, however it hasn’t gained the same level of acceptance as the mechanical mouse due to of the particular surface that is required to operate. The working of the opto-mechanical mouse is the same as what a mechanical mouse does however the position resolvers are built on the optical principle.

(b) Cursor Control Devices

The digitizer illustrated in figure 2.9 is an input device made up of a huge, smooth surface (the appearance is like an actual drawing board) as well as an electronic tracking device that can be moved around the surface in order to follow existing lines. It is a standard technique for CAD systems to extract the coordinates x, y from drawings on paper. Buy Marketing Directors mailing lists online.

The electronic device for tracking has an input switch that allows users to keep track of the desired position of x and y. The coordinates can be recorded into the computer’s memory, or saved in an off-line storage medium like magnetic tape. High resolution digitizers , typically having large boards (e.g. 42 x 60 inches) can offer accuracy and resolution at the level to 0.001 in. It is important to note that the electronic pen and tablet can be regarded as small, low-resolution digitizers.

It is not suitable for three-dimensional mechanical design since the digitizer’s capabilities are limited to two dimensions. Drawings in two dimensions, drafters can easily adjust to the digitizer as it’s similar to draft boards. The digitizer can tilt, elevated or lower to create an ideal place to drafters. Buy Marketing Directors mailing lists online.

The digitizer is able to digitally digitize lines drawn by hand. Users can input data from a sketch or large layout sketch and modify the drawing to achieve the desired degree of precision and clarity. The digitizer is also able to draw a fresh layout, and then edit it to complete the design.

(c) Keyboards

There are a variety of keyboard terminals that are accessible as CAD input devices. The most popular type is the alphanumeric one available in virtually the entire range of interactive systems.

Marketing Directors mailing id lists
Marketing Directors mailing id lists

The alphanumeric terminal is either a CRT, or a hard-copy terminal that prints onto paper. In terms of graphics, the CRT is preferred due to its speed, its ability to edit easily and edit images, as well as the absence massive paper volumes. However it is often desirable and can be easily made using an electronic hard-copy terminal. A lot of CAD software systems employ the graphic screen to display alphanumeric information, however there’s a benefit to having separate CRT terminals to ensure that the alphanumeric message can be made without affecting or overwriting the image displayed on the screen.
The alphanumeric terminal can be utilized to input commands, functions, and additional information into an CAD program. The information will be displayed to verify on the CRT, or written on paper. The system also communicates with the person using the same manner. The computer, as a part of the interactive process will display list of menus and program information, as well as errors, and so on. Buy Marketing Directors mailing id lists online.
