Computer Aided Design or CAD refers to the 2D/3D modelling of physical, structural, and material properties with specialized software on a computer. Engineers and artists use CAD to create architectural designs, animations, ray-traced images, or physics simulations.
In simple terms, CAD is the usage of software to build & document the design procedure of a specific product.
But how did the concept come into existence? To know this, let us look at the understand the background of CAD.
CAD, as discussed above, is used to design a product via computer software. However, the concept of designing, engineering drawing etc., emerged much before such software was developed. The use of engineering drawings goes back over 2000 years. In the eighteenth century, French mathematician Gaspard Monge introduced the concept of orthographic projections.
With time, engineering drawings evolved and slowly gained popularity. Earlier, the designs prepared by engineers were manual and more complex. To tackle these engineering problems, it is essential to analyze and organize them, represent them graphically and have problem-solving principles in place. In engineering, the objects are represented by technical drawing that signifies the physical object's design and specification and the relationship between the data.
CAD’s role becomes crucial as technical drawings need to be accurate, given that they play an essential role in communicating the object information.
CAD allows engineers to design and develop their work on screen. These engineers can save the file and later make any modifications as per their need. Thus, saving a lot of human effort and time.
The application of CAD can be seen across different industries. Through CAD, it is possible to become more creative and improve productivity levels. Gradually, this technology is gaining ground and has become an essential tool for visualizing any product before manufacturing it. Some of the critical advantages of CAD are:

In the present times, there are various types of CAD available and are classified into two types- 2 Dimensional or 2D CAD and 3 Dimensional or 3D CAD.
2 Dimensional or 2D CAD:
It was developed in the 1970s and is the pioneer of CAD software. AT that time, 2D CAD was used in industries like automobile, aerospace and other engineering companies that developed in-house tools to automate the drafting process. In 2D CAD, engineers and software users use shapes like lines, rectangle, circles, or any basic geometric shape to produce a flat drawing.
3 Dimensional or 3D CAD:
3D CAD has gained popularity driven by the growing demand for CAD, improved processing power of computers, and better graphical capabilities. With the help of 3D CAD, the user can create 3D images of the product that look very realistic. These images are called the 3D image and can be rotated on any X, Y or Z-axis.
With the continuous improvement in software technologies, its role has become critical across various sectors and has multiple applications. The benefits of 3D CAD are countless, and it continues to be a game-changer for most of the industries that are using it for developing their products.
As more and more industries shift towards digitization, CAD might have a significant role to play across multiple sectors in the future.
Automation and AI:
In the present times, automation is at the heart of almost everything, and AI has played a crucial role. Possibilities are there that AI would be available with the 3D Modelling software. Undeniably, CAD programs would be able to foresee our actions and enhance the 3D Modelling experience. Users would be able to correct their designing error.
With CAD software’s help, it would be possible to reduce the gap between 3D CAD and reality. For this, CAD software should have excellent 3D tools. Using a virtual reality helmet, users can view 3D models in the way they exist in physical space.
The visualization quality is going a step ahead, and we might see VR options become standard in CAD software functionalities soon.
What is accounts payable? Accounts Payable (AP) is an obligation that an individual or a company has to fulfill for purchasing goods and services bought from their suppliers and vendors. AP refers to the amount that is not paid upfront and can be paid back in a short period of time. Hence, a good or a service purchased on credit to be paid in a short period will fall under AP. For individuals, AP may include the bill paid after availing services such as television network, electricity, internet connection, or telephone. Most of the time, the bill is generated after the designated billing period, depending upon the amount of consumption. The customers have to pay this obligation within a stipulated time to avoid default. What is accounts payable from a Company’s point of View? AP is the amount of money a company is liable to pay to its suppliers or vendors and clear dues for purchases of goods and services purchased from its suppliers or vendors. AP is required to be repaid in a short period, depending on the relationship with suppliers. It is essentially a kind of short-term debt, which is necessary to honour to prevent default. As the current liabilities of the company, AP is required to be settled over the next twelve months. It is presented in the balance sheet as the account payable balance. For example, Entity A buys goods from Entity B for US$400,000.00 on Credit. Entity A has to pay back this amount within 60 days. Entity A will record US$400,000.00 as AP while Entity B will record the same amount as Account receivable. AP is also a part of the cash flow statement. The change in the total AP over a period is shown in the cash flow statement, hence it is part of the company’s working capital. It is widely used in analysing the cash flow of the business and cash flow trends over a period. AP may also depict the bargaining power of the company with its vendor and suppliers. A vendor or supplier may give the customer a longer credit period to settle the cash compared to other customers. The customer here is the company, which will incur AP after buying goods on credit from the vendor. There could be many reasons why the vendor is providing a more extended credit period to the firm such as long-term relationship, bargaining power of the firm, strategic needs of the vendor, the scale of goods or services. By maintaining a more extended repayment period to supplier and shorter cash realisation period from the customer, the company would be able to improve the working capital cycle and need funds to support the business-as-usual. However, prudent working capital management calls for not overtly stretching the payable days as it might lead to dissatisfaction of supplier. Also, investors tend to closely watch the payable days cycle to determine the financial health of the business. When the financial conditions of a firm deteriorate, the management tends to delay the payment to their suppliers. Why accounts payable is an important part of Balance sheet and Cash Flow Statement? As inferred from the previous paragraphs, AP is part of the current liabilities of the balance sheet. This is an obligatory debt that has to be paid back within a time frame so that the company does not default. AP primarily consists of payments to be made to suppliers. If AP keeps on increasing over a period of time, it can be said that the company is purchasing goods or services on credit more, instead of paying up front. If AP decreases, it means the company is reducing its previous debts more than it is buying goods on credit. Managing AP is essential to have a stable cash flow. In a cash flow statement prepared through an indirect method, the net difference in AP is shown under cash flow from operating activities. The business entity can use AP to create the desired variation in the cash flow to some extent. For example, to increase cash reserves, management can increase the duration of paying back the credit taken for a certain period, thus affecting the net difference in AP. What Is the Role of Accounts Payable Department? Every company has an accounts payable department and the size and structure depend upon how big or small the enterprise is. The AP department is formed based on the estimated number of suppliers, vendors, and service providers the company is expected to interact with; the amount of payment volume that would be processed in a given period of time; and the nature of reports that a management will require. For example, a tiny firm with a low volume of purchase transactions may require a simple or a basic accounts payable process. However, a medium or a large enterprise may have a accounts payable department that may require a set of practices to be followed before paying back the credit. What is the Accounts Payable Process? Guidelines or a process is important as it provides transparency and smoothness in facilitating the volume of transactions in any time period. The process involves: Bill receipt: when goods were bought, a bill records the quantity of goods received and the amount that needs to be paid to the vendors. Assessing the bill details: to ensure that the bill or invoice copy includes the name of the vendor, authorization, date of the purchase made and to verify the requirements regarding the purchase order. Updating book of records after the bill is collected: Ledger accounts need to be revised on the basis of bills received. The department makes an expense entry after taking approval from management. Timely payment processing: the department takes care of all payments that need to be processed on or before their due date as mentioned on a bill. The department prepares and verifies all the required documents. All details entered on the cheque along with bank account details of the vendor, payment vouchers, the purchase order, and the original bill and purchase order are scrutinized. The department also takes care of the safety of the company’s cash and assets and prevents: reimbursing a fake invoice reimbursing an incorrect invoice making double payment of the same vendor invoice Apart from making supplier payments, AP departments also takes care of travel expenses, making internal payments, maintaining records of vendor payments, and reducing costs Business Travel Expenses: Bigger entities or firms whose business nature requires all personnel to travel, have their AP department manage their travel costs. The AP department manages the personnel’s travel by making advance payments to travel companies including airlines and car rentals and making hotel reservations. An account payable department may also deals with requests and fund distribution to cover travel costs. After business travel, AP may also be responsible for settling funds supplied versus actual funds spent. Internal Payments: The Accounts Payable department takes care of internal reimbursement payments distribution, controlling and petty cash controlling and administering, and controlling sales tax exemption certificates distribution. Internal reimbursement payments include receipts or both substantiate reimbursement requests. Petty cash controlling and administering includes petty expenses such as out-of-pocket office supplies or miscellaneous postage, company meeting lunch. Sales tax exemption certificates comprise AP department handling sales tax exemption certificates supply to managers to make sure qualifying business purchases excludes sales tax expense. Maintaining Records of Vendor Payments: Accounts Payable maintains information of vendor contact, terms of payment and information of Internal Revenue Service W-9 either manually or on a computer database. The AP department lets management know through reports on how much the business owes at present. Other Functions: The accounts payable department is also responsible to lessen costs by identifying cost structures and creating strategies to reduce the spending of business money. For example, minimising cost by making payment of the invoice within a discount period. The AP department also acts as a direct point of contact between an entity and the vendor. How to Calculate Accounts Payable in Financial Modelling Financial modelling enables calculating the average number of days a company takes to make bill payments. AP days can be calculated using the following formula: AP value can be calculated using the following formula: What is accounts payable turnover ratio? AP turnover ratio shows the capability of a firm to pay cash to its customer after credit purchases. It is counted as an essential ratio to analyse the cash management attribute of the firm and its relationship with vendors or suppliers. It is calculated by dividing purchases by average AP. Purchases by the company are calculated as the sum of the cost of sales and net inventory in a given period: Now let’s understand this with the help of an example. Let us suppose, Cost of sales of Company XYZ for the period was $60,000, and XYZ began with inventories worth $21000 and ended at $15000. AP at the beginning was $20000, and $15000 at the end. Now the purchases will be $66000 (60000+21000-15000). The average AP will be $17500. Therefore, the AP turnover ratio will be 3.77x. Dividing the number of weeks in a year by the AP turnover ratio will give the number of weeks the company takes on average to settle its payables. In this case, it will be around 13.8 weeks (52/3.77). What is the difference between Accounts Payable vs. Trade Payables? Though the phrases "accounts payable" and "trade payables" are used interchangeably, the phrases have slight differences. Trade payables is the cash that a company is obligated to pay to its vendors for goods and supplies which are part of the inventory. Accounts payable include all of the short-term debts or obligations of a company.
What is Day Trading? Day trading is popular among a section of market participants. It is a type of speculation wherein trades are squared-off before the market close in the same day. An individual or a group is engaged in buying and selling of securities for a short period for profits, the trades could be active for seconds, minutes or hours. One can engage in day trading of many securities in the market. Anyone who has sufficient capital to fund the purchase can engage in day trading. For a class of people, day trading is a full-time job. Day traders are agnostic to the long-term implications of the security and motive is to benefit from the price changes on either side and make profit out of the asset price fluctuations within a day. They bet on price movements of the security and are not averse to take short positions to benefit from the fall in price. Day trading is not only popular among individuals or retail traders but institutional traders as well, therefore the price movements are large sometimes depending on the magnitude of information flow and accessibility. Everyone wants to make money faster, and many are inclined to speculate in markets, but it comes with considerable risk and potential loss of capital. People engaged in day trading also incur losses, and oftentimes outcomes are disheartening. Day trading is a risky activity, similar to sports betting and gambling, and it could become addictive just like gambling and sports betting. Since the motive is to earn profits, the profits realised from day trading also tempt people to continue speculating. People spend considerable time and efforts to make the most out of day trading. They have to continuously absorb and incorporate information flow, which has become increasingly accessible driven by new-age communications systems like Twitter, Facebook, forums etc. But not only information flows have been favourable, day traders are now equipped with best in class infrastructure to execute trades even on compact devices like mobile phones. The accessibility to markets is at a paramount level and gone are days of phone call trading and lack of information flows. What are the essentials for Day Trading? Basic knowledge of markets With lack of basic knowledge of markets, day trading may yield unacceptable outcomes. It becomes imperative for people to know what’s on the stake. Prospective day traders should know about capital markets, and the securities traded in capital markets like bonds, equity and derivatives. Buying shares and expecting a return from the price movements are on the to-do list for many. However, it is important to know about and risks and potential returns from speculating in capital markets. After getting some basic knowledge about markets and securities, aspiring day traders should know how to analyse market prices of securities through fundamental analysis and technical analysis. Although day traders don’t practice fundamental analysis extensively, they spend considerable time to apply technical analysis, to formulate a entry and exit strategy. Device and internet connection Trading is now possible on mobile applications as well as computer applications or websites. An aspiring day trader will likely begin with mobile phone given the accessibility, and laptops/computers are useful as scale grows larger and complex. Internet connection is prerequisite to practising day trading, and it is favourable to have a fast internet connection to avoid glitches and potential problems. These perquisites are now available with large sections of societies. Broker and trading platform A broker will facilitate a market for potential trades. The security brokerage industry has also seen a profound shift as technology has driven cost lower while competition is ramping up across jurisdictions. Large retail brokerages have moved towards zero commission trading in the U.S., and the same is seen being the trend across other geographies as well. The entry of discount and online brokerages has perhaps given wings to the retail market participants as well as the retail market for security brokers. Robinhood has grown immensely popular in the United States, but there are many firms like Robinhood in other jurisdictions. Each country has some firms with business model on same lines as Robinhood. Brokers now offer high-quality mobile applications and web services to clients, and trading security has never been so accessible. They also provide access to the global market along with a range of securities, including commodity derivatives, currency derivatives, CFDs, options, futures, bond futures etc. Real-time market information flow On public sources, market price information is at times not live due technical shortcomings, which will not work appropriately, especially for day traders. Brokers not only provide platform and market but several other services, including margin lending, real-time data, research. Day traders closely track prices of securities and overall information flow to incorporate developments in bidding, and real-time data provides accurate prices throughout market hours. Information flow largely relates to the news around the company, industry or economy. Day traders now have far better sources of information than the conventional sources, and sometimes these sources could be exclusive to a group. What are the risks of day trading? Most of the aspiring day traders end up losing money, given the lack of experience and knowledge. They should rather only bet on capital that they are comfortable to loose, in short, they should avoid risk of ruin. Day trading is sort of pure-play speculation and application of knowledge, information flow, laced with good trading system is paramount. The only concern of day traders is movement in price, which contradicts from investments. Day traders try to time and ride the momentum in the price and exit the trade before momentum turns otherwise, which can happen frequently. It consumes considerable time and induces stress on the individuals given the nature of security prices, which can move north and south abruptly throughout the day, hours, minutes and seconds. Day traders should have enough capital to trade in cash instead of margin. Day trading on margin or borrowed money is extremely risky and has the potential to make a person insolvent, especially in cases of extreme risk-taking. The leverage associated with borrowed money magnifies profits as well as losses. Aspiring day traders should equip themselves with adequate knowledge, competency and sound risk management process. Although fast money is dear to most, it is better to know what is at stake before jumping into markets with excitement.

What is depreciation? Depreciation is an accounting method used to allocate the cost of a tangible asset to the books of accounts over the useful life of the asset. It is essentially the accounting for wear and tear on the asset over its useful life. Depreciation also refers to the value of the asset that has been used over time. Assets of a firm that are used for over a one-year period largely include physical assets. Although firms incur expense while purchasing these assets, the expenses are not charged in the income statement. Such assets are recorded in the balance sheet of the firm and are expensed on the income statement as depreciation expense over time during the life of the asset. The tax authorities also decide the useful life of assets because overstating depreciation expense can lower tax liability. Now assets come in two variety: tangible assets and intangible assets. As the name suggests tangible, the tangible assets can be touched, such as equipment, machinery, computers, vehicles etc. Depreciation is used to expense the tangible assets of a firm. Intangible assets cannot be touched and include assets like licenses, copyrights, patents, brand names, logos etc. Amortisation of assets is an accounting method similar to depreciation used to expense intangible assets. Long-term assets are the source of generating revenue for firms over a long period of time, therefore the cost of acquiring tangible long-term assets is not expensed fully at the time of purchases and is expensed over the life of the asset. As the asset is used over periods, the carrying value of an asset in the balance sheet is reduced over time. Carrying value of an asset is the original cost minus accumulated depreciation on the asset over time. Since the cost of acquiring the long-term tangible asset is not expensed fully at the time of purchase and is expensed over its useful life, the depreciation expense is a non-cash charge because actual cash outgo was incurred at the time of purchase. But depreciation expense reduces the reported earnings of the company as it is charged on the income statement of the firm. Since the expenses are deducted from the revenue of the firm, the tax liability of the firm is also reduced. What are the methods of depreciation? Straight-line method The straight-line method is the most common method of depreciating an asset over its life. Under this method, the recurring depreciating amount of the asset remains constant and is not changed over the life of the asset. For example, a firm buys a machine for $10000 with a salvage value of $2000, and the useful life of the asset is ten years. The depreciable value of the asset will be $8000, which is the cost of machine minus salvage value. Now the firm will depreciate the $8000 each year at a rate of $800 per year. The per-year depreciation charge of $800 is the depreciable value of the asset divided by the useful life of the asset (8000/10). Double declining balance depreciation method It is an accelerated type of depreciation method. Under this method, the depreciation expense in higher in the beginning years and gradually reduces over the life of an asset. It also reflects that assets are more valuable in the early years of production compared to later years. In this method, the subsequent depreciation charges after the initial charge are calculated using the ending balance of the asset in the last period. Ending balance of the asset is the original cost of the asset less accumulated depreciation. Also, the depreciation factor in this method is twice of the straight-line method. Depreciation expense = (100%/Useful life of asset) x 2 Why is depreciation due diligence important? Depreciation can be used to manipulate the financials of the company. Overstating and understating depreciation charges directly impacts the profit of the company. When a firm is charging less depreciation than required, it would directly increase the profits of the firm. When depreciation expense is lesser than the actual expense, the income statement will record lower amount of expenses, therefore the deductions from revenue will lesser and profits will increase. Investors also assess whether the useful life of asset used in calculating the depreciation of firm is appropriate or not. The companies should use an appropriate useful life of the asset. When the useful life of the asset is increased, the depreciation charges will spread across an increased number of years. As a result, the depreciation expenses during the life of an asset would be understated since the actual life of an asset is less than recorded. Investors prefer checking the number of years used as the useful life of an asset. Sometimes firms may choose to change the method of depreciation. Although it could be appropriate when actual business conditions don’t match the method adopted, there remains a possibility that the decision to change the method could be driven by the motive to manipulate depreciation expenses. Companies may seek to keep the assets in the balance sheet even though the asset is of no use. This will help the company to keep incurring depreciation expense on the income statement and reduce the tax liability of the business. When the value of assets of the company has appreciated in light of the market environment, the balance sheet value of the asset will also increase. When the balance sheet value of an asset is increased, the depreciation charges should also increase. Therefore, appreciation in the value of an asset should also increase depreciation expense for the company.
