  2. Electrical drawing - Wikipedia

    en.wikipedia.org/wiki/Electrical_drawing

    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".

  3. Structural drawing - Wikipedia

    en.wikipedia.org/wiki/Structural_drawing

    The structural plan drawings show the foundation, floor, and roof plan of the building. These plans provide information like size and location of the structural elements present in the respective plans. Elevations show the exterior walls of a building or structure. In elevation drawings you can find the height of building (floors and roof ...

    CAD: computer-aided design, computer-aided drafting; cadmium [plating] CAGE: Commercial and Government Entity [code] A CAGE code is a unique identifier to label an entity (that is, a specific government agency or corporation at a specific site) that is a CDA, ODA, or MFR of the part defined by the drawing. One corporation can have many CAGE ...

  5. FreeCAD - Wikipedia

    en.wikipedia.org/wiki/FreeCAD

    FreeCAD is a general-purpose parametric 3D computer-aided design (CAD) modeler and a building information modeling (BIM) software application with finite element method (FEM) support. [4] It is intended for mechanical engineering product design but also expands to a wider range of uses around engineering, such as architecture or electrical ...

  6. Light plot - Wikipedia

    en.wikipedia.org/wiki/Light_plot

    The supplementary (and generally optional) section (side) and elevation (front) views contain much of the same information as the plan view. The section is a cutaway view of the house and stage from either the left or the right. The section line is typically the venue's center line. The elevation is a plot oriented as if viewing the stage from ...

  7. Freeform surface modelling - Wikipedia

    en.wikipedia.org/wiki/Freeform_surface_modelling

    Freeform surface modelling is a technique for engineering freeform surfaces with a CAD or CAID system.. The technology has encompassed two main fields. Either creating aesthetic surfaces (class A surfaces) that also perform a function; for example, car bodies and consumer product outer forms, or technical surfaces for components such as gas turbine blades and other fluid dynamic engineering ...

  8. Overhead power line - Wikipedia

    en.wikipedia.org/wiki/Overhead_power_line

    For an "H"-type wood pole structure, two poles are placed in the ground, then a crossbar is placed on top of these, extending to both sides. The insulators are attached at the ends and in the middle. Lattice tower structures have two common forms. One has a pyramidal base, then a vertical section, where three crossarms extend out, typically ...

  9. Single-line diagram - Wikipedia

    en.wikipedia.org/wiki/Single-line_diagram

    A typical one-line diagram with annotated power flows. Red boxes represent circuit breakers, grey lines represent three-phase bus and interconnecting conductors, the orange circle represents an electric generator, the green spiral is an inductor, and the three overlapping blue circles represent a double-wound transformer with a tertiary winding.
