Block Diagrams

Block diagram is a diagram of such a system where the principal functions are depicted with the help of blocks. These blocks are usually connected by lines and such lines are known to be representing the relationships of the blocks.

Being widely used in engineering in electronic design, hardware design, software design and other kinds of engineering activity, block diagrams are usually used for providing with the less detailed descriptions, being intended to clarify all the overall concepts having no concern for the details of implementation.

Making an analogy to the map making world, any block diagram is known to have a few similarities to a highway map. The major cities may be listed but the minor county roads as well as the city streets are not mentioned in this drawing.

Providing the ConceptDraw DIAGRAM diagramming and drawing software’s users with the pre-made templates, samples and stencil libraries full of vector elements, Block Diagrams solution can be used for drawing any needed block diagram.

Using the created block diagrams for visualizing the high-levelled concepts of engineering, software system design and business, any business owner has a chance to succeed in doing what he is meant to.

Using all five stencil libraries that contain 190 vector stencils taken from the Block Diagrams solution as well as the examples, it may become possible to make the needed drawing within only a few minutes by editing the existing ones.

Many business specialists, business owners and project managers will find the Block Diagrams solution useful for drawing the 3D block diagrams as using the pre-designed objects from the solution’s libraries can simplify the work of drawing making it possible to complete the tasks within only a few minutes.

There are 5 libraries containing 190 vector stencils in the Block Diagrams solution.

There are a few samples that you see on this page which were created in the ConceptDraw DIAGRAM application by using the Block Diagrams solution. Some of the solution's capabilities as well as the professional results which you can achieve are all demonstrated here on this page.

All source documents are vector graphic documents which are always available for modifying, reviewing and/or converting to many different formats, such as MS PowerPoint, PDF file, MS Visio, and many other graphic ones from the ConceptDraw Solution Park or ConceptDraw STORE. The Block Diagrams solution is available to all ConceptDraw DIAGRAM users to get installed and used while working in the ConceptDraw DIAGRAM diagramming and drawing software.

Example 1: Block Diagram — Document Management System Architecture

This diagram was created in ConceptDraw DIAGRAM using the blocks with perspective library in the Block Diagrams Solution. An experienced user spent 15 minutes creating this sample.

This sample shows the parts of a document-management system. These parts are represented as 3D blocks. Drawing the 3D diagrams is a quite complex process. But using the predesigned objects from the ConceptDraw DIAGRAM libraries you can design your 3D block diagrams in a few minutes.

Block Diagrams

When using the term block diagram, we are referring to a whole sub-set of system diagrams, that use a series of blocks to represent components or actions, and connecting lines that show the relationship between those blocks. They are typically low-detail, providing an overview of a process without necessarily going into the specifics of implementation. A common example of a block diagram is a flowchart, used in many fields of business as a simple way of mapping a repeated process. Software and hardware designers use them to record the design process, network managers can show the relationships between electrical systems. The principle aim is to allow a critical view to be taken on the steps in a process or system — information on physical components or construction is left to schematic diagrams or blueprints.

Not all block diagrams are the same...

Although essentially a very simple format, a variety of shapes and connecting lines, and rules and actions pertaining to them, make the block diagram a versatile tool for many forms of industry. Another attraction is the ease with which they can be constructed — ConceptDraw DIAGRAM is an example of purpose built software designed with this form of process modeling in mind. The RapidDraw functionality found within creates new objects and their connectors in a single-click, creating an ever expanding tree as you work through the process.

Here are some examples of the sort of subject matter block diagrams can be useful for, and what style can be utilized in each case.


Quite a broad term, but you will find block diagrams used in all fields of business; at an abstract level, to describe customer intentions and management processes, to depictions of physical transactions such as product design and sales processes.

  • Business process modeling makes use flowcharts, control flow diagrams and data flow diagrams to show key parts of employee workflow.
  • Management diagrams include organizational charts, product lifecycles, and influence diagrams to make decisions and regulate the workforce.
  • Marketing diagrams involve decision trees, Porter's five forces models, and strategy maps to help identify and cater for customer routine.
  • Finance divisions rely on accounting and audit flowcharts to record and approbate account strategy.

The format of block diagrams lend themselves well to system and software modeling — often these sorts of processes involve logical, binary choice relationships with a finite number of permutations or possibilities. They can be used to identify or predict possible faults in a system.

  • To map internal software architecture, UML diagrams, data and function models, IDEF diagrams, or functional flow block diagrams can be used. Entity–relationship diagram (ERD), SDL diagrams, systems development life cycles (SDLC) are used to describe the relationship between components within a system.
  • To maintain safety and reliability standards, fault tree analysis diagrams are used to find any flaws in a product or process.
  • Electronic engineers who need to record complex relationships between electrical components will employ a functional block diagram.


As well as describing linear system processes and patterns of product lifecycles or customer behaviour, block diagrams can describe more free-form, creative diagrams for educational purposes — connecting thematic ideas and structuring concepts into a visual hierarchy for effective understanding and learning. Diagrams of this form, which can include mind maps and concept maps, bring a collaborative element to learning whereby subjects can be 'brainstormed' by people within a group.

  • Mind maps, concept maps and conceptual graphs are all concerned with learning through visualization techniques. Key areas of information regarding a subject are identified, and the diagram shows the relationship and relevance to each other.

  • Cycle visualization, or life cycle charts, are an effective way of showing repeated processes found in nature, weather cycles for example.
  • Tree diagrams express hierarchy within a subject; for instance the family tree of a monarchy, or branches of language and their subsequent dialects.

A multi — purpose solution

Not many software programs can claim to offer solutions for all the tasks mentioned, or are capable of such diverse functionality as to handle complex designs in a variety of formats. CS Odessa have devoted a number of years to ensuring that ConceptDraw DIAGRAM offers value in all these situations; for producing informative educational materials, professional looking system analysis, or constructing complex business processes, and much more besides.

A large portion of ConceptDraw Solution Park is devoted entirely to the principle of block diagrams in all its varied forms — each individual solution contains their own vector stencil libraries, full of task specific icons and templates, sample documents that provide a reference of the capabilities of the solution, as well as a host of associated help and how-to material (text and video).

A couple of key features separate ConceptDraw DIAGRAM from the crowd in terms of ease of use, and assistance when creating your block diagram. RapidDraw functionality allows the user to place objects on the page with a single click, automatically connecting to the previous shape, making the drawing process fluid and intuitive. The technology to connect objects has also been carefully considered — 'smart connectors' automatically choose the most efficient route between shapes, and realign themselves if objects are rearranged at any point.
