Electrical Engineering

The vector stencils library "Qualifying" contains 56 qualifying symbols of radiation, polarity, phase, windings, wire, ground, connection, connector, coaxial, electret.
Use these signs to annotate or specify characteristics of objects in electrical drawings, electronic schematics, circuit diagrams, electromechanical drawings, and wiring diagrams, cabling layout diagrams.
"An electrical drawing, is a type of technical drawing that shows information about power, lighting, and communication for an engineering or architectural project. Any electrical working drawing consists of "lines, symbols, dimensions, and notations to accurately convey an engineering's design to the workers, who install the electrical system on the job".
A complete set of working drawings for the average electrical system in large projects usually consists of:
(1) A plot plan showing the building's location and outside electrical wiring.
(2) Floor plans showing the location of electrical systems on every floor.
(3) Power-riser diagrams showing panel boards.
(4) Control wiring diagrams.
(5) Schedules and other information in combination with construction drawings.
Electrical drafters prepare wiring and layout diagrams used by workers who erect, install, and repair electrical equipment and wiring in communication centers, power plants, electrical distribution systems, and buildings." [Electrical drawing. Wikipedia]
The signs example "Design elements - Qualifying" was drawn using the ConceptDraw PRO diagramming and vector drawing software extended with the Electrical Engineering solution from the Engineering area of ConceptDraw Solution Park.

The design elements library Tables contains 27 symbols of tables.
Use the vector stencils library Tables to develop house floor plans, home designs, kitchen and dining room design and furniture layout of cafe or restaurant.
"A table is a form of furniture with a flat horizontal upper surface used to support objects of interest, for storage, show, and/ or manipulation. The surface must be held stable; for reasons of simplicity, this is usually done by support from below by either a column, a "base", or at least three columnar "stands". In special situations, table surfaces may be supported from a nearby wall, or suspended from above.
Common design elements include:
top surfaces of various shapes, including rectangular, rounded, or semi-circular;
legs arranged in two or more similar pairs;
several geometries of folding table that can be collapsed into a smaller volume;
heights ranging up and down from the most common 18–30 inches (46–76 cm) range, often reflecting the height of chairs or bar stools used as seating for people making use of a table, as for eating or performing various manipulations of objects resting on a table;
presence or absence of drawers;
expansion of the surface by insertion of leaves or locking hinged drop leaf sections into horizontal position.
Desks are tables specifically intended for information-manipulation tasks, including writing and use of interactive electronics.
Tables of various shapes, heights, and sizes are designed for specific uses:
Dining room tables are designed to be used for formal dining.
Bedside tables, nightstands, or night tables are small tables used in a bedroom. They are often used for convenient placement of a small lamp, alarm clock, glasses, or other personal items.
Gateleg tables have one or two hinged leaves supported by hinged legs.
Coffee tables are low tables designed for use in a living room, in front of a sofa, for convenient placement of drinks, books, or other personal items.
Refectory tables are long tables designed to seat many people for meals.
Drafting tables usually have a top that can be tilted for making a large or technical drawing. They may also have a ruler or similar element integrated.
Workbenches are sturdy tables, often elevated for use with a high stool or while standing, which are used for assembly, repairs, or other precision handwork.
Nested tables are a set of small tables of graduated size that can be stacked together, each fitting within the one immediately larger. They are for occasional use (such as a tea party), hence the stackable design." [Table (furniture). Wikipedia]
The shapes library Tables is provided by the Floor Plans solution from the Building Plans area of ConceptDraw Solution Park.
