## How to Create Flowchart Using Standard Flowchart Symbols

Flowcharts are used to display an algorithm for consistent execution of certain steps. Flowchart is probably the easiest way to make a graphical representation of any process. Flowcharts use the set of standard geometric symbols and arrows to define relationships. ConceptDraw PRO allows you to create professional flowchart quickly and easily. The ability to create flowcharts is contained in the Flowcharts solution. The solution provides a set of special tools for creating flowcharts.The vector stencils library "Dimensioning and tolerancing" contains 45 symbols of geometric dimensions and mechanical tolerances, geometric symbols, callouts, and text boxes and inserts.

Use these geometric dimensioning and tolerancing (GD&T) shapes to create annotated mechanical drawings.

"Geometric dimensioning and tolerancing (GD&T) is a system for defining and communicating engineering tolerances. It uses a symbolic language on engineering drawings and computer-generated three-dimensional solid models that explicitly describes nominal geometry and its allowable variation. It tells the manufacturing staff and machines what degree of accuracy and precision is needed on each controlled feature of the part. GD&T is used to define the nominal (theoretically perfect) geometry of parts and assemblies, to define the allowable variation in form and possible size of individual features, and to define the allowable variation between features."

Mathematics solution provides 3 libraries: Plane Geometry Library, Solid Geometry Library, Trigonometric Functions Library.## Definition Flowchart

A flowchart is a type of diagram that represents an algorithm, workflow or process, showing the steps as boxes of various kinds, and their order by connecting them with arrows. This definition flowchart gives a clear answer for the question "What is a flowchart?". It is convenient to use a powerful ConceptDraw PRO software extended with Flowcharts Solution from the "Diagrams" Area of ConceptDraw Solution Park to design flowcharts of various types which will additionally illustrate a definition flowchart.HelpDesk

## How to Draw Geometric Shapes in ConceptDraw PRO

Knowledge of geometry grants people good logic, abstract and spatial thinking skills. The object of study of geometry are the size, shape and position, the 2-dimensional and 3-dimensional shapes. Geometry is related to many other areas in math, and is used daily by engineers, architects, designers and many other professionals. Today, the objects of geometry are not only shapes and solids. It deals with properties and relationships and looks much more about analysis and reasoning. Geometry drawings can be helpful when you study the geometry, or need to illustrate the some investigation related to geometry. ConceptDraw PRO allows you to draw plane and solid geometry shapes quickly and easily.## Mathematics

Mathematics solution extends ConceptDraw PRO software with templates, samples and libraries of vector stencils for drawing the mathematical illustrations, diagrams and charts.

The vector stencils library "Optics" contains 17 symbol icons: reflecting surface; convex and concave lens with and without optic axis, body or ray; ray; parallel beam of light; point light source; prism with and without ray path; refraction.

Use these shapes for drawing schemes of physical experiments in geometrical optics and ray tracing diagrams.

"Geometrical optics, or ray optics, describes light propagation in terms of "rays". The "ray" in geometric optics is an abstraction, or "instrument", which can be used to approximately model how light will propagate. Light rays are defined to propagate in a rectilinear path as they travel in a homogeneous medium. Rays bend (and may split in two) at the interface between two dissimilar media, may curve in a medium where the refractive index changes, and may be absorbed and reflected. Geometrical optics provides rules, which may depend on the color (wavelength) of the ray, for propagating these rays through an optical system. This is a significant simplification of optics that fails to account for optical effects such as diffraction and interference. It is an excellent approximation, however, when the wavelength is very small compared with the size of structures with which the light interacts. Geometric optics can be used to describe the geometrical aspects of imaging, including optical aberrations." [Geometrical optics. Wikipedia]

## ERD Symbols and Meanings

Entity Relationship Diagram (ERD) is a popular software engineering tool for database modeling and illustration the logical structure of databases, which uses one of two notations - Chen's or Crow’s Foot. Crow's foot notation is effective when used in software engineering, information engineering, structured systems analysis and design. Each of these notations applies its own set of ERD symbols. Crow's foot diagrams use boxes to represent entities and lines between these boxes to show relationships. Varied shapes at the ends of lines depict the cardinality of a given relationship. Chen's ERD notation is more detailed way to represent entities and relationships. ConceptDraw PRO application enhanced with all-inclusive Entity-Relationship Diagram (ERD) solution allows design professional ER diagrams with Chen's or Crow’s Foot notation on your choice. It contains the full set of ready-to-use standardized ERD symbols and meanings helpful for quickly drawing, collection of predesigned ERD samples, examples and templates.
