Mechanical Drawing Symbols

Working as a mechanic being responsible for making the appropriate drawings, including technical ones, working with ventilating, heating or air conditioning, you may find it exhausting creating all of schemes by hand using the ruler, for example. In this case we can recommend to download ConceptDraw DIAGRAM which is professional software that can make your life simpler and help you to achieve your goals at work in your business.

Mechanical systems drawing is a type of technical drawing that shows information about heating, ventilating, and air conditioning. It is a powerful tool that helps analyze complex systems. These drawings are often a set of detailed drawings used for construction projects; it is a requirement for all HVAC work. They are based on the floor and reflected ceiling plans of the architect. After the mechanical drawings are complete, they become part of the construction drawings, which is then used to apply for a building permit. They are also used to determine the price of the project.

ConceptDraw DIAGRAM diagramming and vector drawing software extended with Mechanical Engineering solution from the Engineering area of ConceptDraw Solution Park provides a set of drawing tools and predesigned mechanical drawing symbols for fast and easy design various mechanical engineering diagrams, drawings and schematics.

Sales Process Flowchart. Flowchart Examples →

Process mapping helps with sharing business results and reorganizing workflow. In almost every case, after creating a sales process flowchart the steps that are redundant become obvious for a manager. It's easy to find a flowchart examples that will help in developing one for your business. This sales process flowchart consists of a sequence of steps that represent a simple sale process. Each step is shown graphically by a rectangle representing processing steps or an activity, or a diamond representing a decision. These rectangles are linked by arrows, that indicate the direction of the sales workflow. ConceptDraw Sales Flowcharts solution delivers a the full set of classical flowchart notation symbols, along with sales-related icons and pictograms.Sales Process Flowchart. <br>Flowchart Examples *

How To Create Restaurant Floor Plan in Minutes →

As restaurant industry is growing rapidly nowadays, researches show that almost half of the adults have worked in a restaurant or a cafe. Moreover, many of them dream to start their own someday. Unfortunately, it takes a lot of time to write a business plan and to find a great location, although some know how to create a restaurant floor plan in minutes or how to plan budget effortlessly. Hiring employees can also cause a lot of headache, but this is crucial for further success, because every guest comes to restaurant for a good service and delicious food. It is also worth noting that restaurant concept is also important, because it defines target audience and influences the menu. This diagram represents the floor plan of an ongoing sports-theme establishment - restaurant, cafe, or other food service. A number of widescreen monitors installed along the perimeter provide visitors the opportunity to follow the course of a match from anywhere in the dining room of restaurant or cafe. The most of sports fans believe that food and alcohol is a big part of any sports show. That is why the dining room takes the most space - almost 60% of the total establishment space. Nearly all sports fans consume beverages while watching sports - beer, soda or water at least. Thus, the restaurant floor plan designers added a large lavatory there. Moreover, project developers considered unnecessary the gender division of such delicate place - perhaps they guess that only men are watching football, or believe that alcohol will eliminate the most of gender differences.Restaurant Floor Plan

Types of Flowchart - Overview →

A flowchart is a powerful tool for examining processes. It helps improving processes a lot, as it becomes much easier to communicate between involved people, to identify potential problems and to optimize workflow. There are flowcharts of different shapes, sizes and types of flowchart vary from quite basic process flowcharts to complex program flowcharts. Nevertheless, all these diagrams use the same set of special symbols like arrows to connect blocks, parallelogram to show data receiving or rectangles for showing process steps. Basic flowcharts are used to represent a simple process algorithm. A basic flowchart notation consists of rectangles (business processes), arrows (the flow of information, documents, etc.). The same notation is used in items such as the "decision", which allow you to do the branching. To indicate the start of the entire business process and its termination can be used the "Terminator" element. The advantages of Basic Flowchart are simplicity and clarity. With it you can quickly describe the business process steps. Creating of Basic Flowchart does not require any special knowledge, as easily understand by employees with different levels of education and IQ.Types of Flowchart - Overview *

Electrical Symbols — VHF UHF SHF →

Ultra high frequency (UHF) is the ITU designation for radio frequencies in the range between 300 MHz and 3 GHz, also known as the decimetre band as the wavelengths range from one meter to one decimetre. Radio waves with frequencies above the UHF band fall into the SHF (super-high frequency) or microwave frequency range. Lower frequency signals fall into the VHF (very high frequency) or lower bands. UHF radio waves propagate mainly by line of sight; they are blocked by hills and large buildings although the transmission through building walls is strong enough for indoor reception. They are used for television broadcasting, cell phones, satellite communication including GPS, personal radio services including Wi-Fi and Bluetooth, walkie-talkies, cordless phones, and numerous other applications. 26 libraries of the Electrical Engineering Solution of ConceptDraw DIAGRAM make your electrical diagramming simple, efficient, and effective. You can simply and quickly drop the ready-to-use objects from libraries into your document to create the electrical diagram.Electrical Symbols — VHF UHF SHF *
