A qualifying symbol is graphics or text added to the basic outline of a device’s logic symbol to describe the physical or logical characteristics of the device.

How to Create an Electrical Diagram Using Qualifying Library

  • Open ConceptDraw DIAGRAM new document page.
  • Select libraries from Electrical Engineering section.

    Libraries from Electrical Engineering section

  • There are a few different ways to place an object into your drawing:

    • Click on an object and then click on the document, at the place you want the object to be inserted.
    • Perform a drag-and-drop from the library to your document.
    • Double click on an object’s icon in the library to place an object in the center of your document.
  • Select the Smart Connector tool Smart Connector. To connect elements using this tool, drag the connector from one connect dot to another.You can use Layers to place connections on different layers.
  • Result: Electrical Diagram.

Circuits and Logic Diagram Software →

A circuit diagram is sometimes also called an elementary diagram, electronic schematic or electrical diagram circuits. It is essential in construction of any electronic equipment. Among many digital drawing tools available, ConceptDraw DIAGRAM is a leading circuits and logic diagram software, affording for easy and quick creation of even the most advanced and complex diagram designs. This makes it a perfect choice for computer science and any kind of electronic engineering. This drawing includes the graphic symbols that may be in use while creating a logic circuit diagram. The diagrams of such kind are used in the electronics industry. The logic symbol depicts a device that realizes a Boolean type functions. Practically a logic symbol means transistor, diodes, relays, and other mechanical or optical details which provide function of closing or opening "gates". Totally the logic circuits can involve millions of gates. ConceptDraw Electrical Engineering solution gives the opportunity to create a circuit diagrams both simple and difficult.Circuits and Logic Diagram Software *

Network Glossary Definition →

When talking about engineering, one should define all the terms used, so anybody could understand the topic. Typical network glossary contains definitions of numerous network appliances, types of networks and cable systems. The understanding of basic is crucial for server management, network administration and investigating problems. The network glossary defines terms related to networking and communications. The most of glossary items has their visual representation in ConceptDraw DIAGRAM libraries of the Computer Network Diagrams solution. This illustration presents a local area network (LAN) diagram. It designed to show the way the interaction of network devices in a local network. The diagram uses a library containing symbols of network equipment, connections and the end-point devices such as network printer, hubs, server, modem and finally computers (PC, mac, laptop). This diagram depicts a physical LAN topology.Network Glossary Definition *

Electrical Symbols — MOSFET →

The metal–oxide–semiconductor field-effect transistor (MOSFET, MOS-FET, or MOS FET) is a type of transistor used for amplifying or switching electronic signals. Although the MOSFET is a four-terminal device with source (S), gate (G), drain (D), and body (B) terminals, the body (or substrate) of the MOSFET is often connected to the source terminal, making it a three-terminal device like other field-effect transistors. Because these two terminals are normally connected to each other (short-circuited) internally, only three terminals appear in electrical diagrams. The MOSFET is by far the most common transistor in both digital and analog circuits, though the bipolar junction transistor was at one time much more common. 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 — MOSFET *

Technical Drawing Software →

Engineering students usually have huge amount of homework. Learning how to develop a technical drawing is one of the necessary skills. Luckily, at the present time, there’s no need to draw it on paper, because there a lot of software tools for it. This drawing represents the Bearing symbols library, that is the part of the ConceptDraw Mechanical Engineering solution. Bearings are the important components of any movable mechanism. The function of bearing is to align, guide, and support the moving parts in any mechanical construction. Usually they are located between moving and stationary parts, it works as a connection point between them. Using Mechanical Engineering solution and ConceptDraw DIAGRAM one can effortlessly draw engineering diagrams of any complexity.Technical Drawing Software *
