  2. Heliodon - Wikipedia

    en.wikipedia.org/wiki/Heliodon

    Heliodons are used primarily by architects and students of architecture. By placing a model building on the heliodon’s flat surface and making adjustments to the light/surface angle, the investigator can see how the building would look in the three-dimensional solar beam at various dates and times of day.

  3. Architectural drawing - Wikipedia

    en.wikipedia.org/wiki/Architectural_drawing

    An architectural drawing or architect's drawing is a technical drawing of a building (or building project) that falls within the definition of architecture.Architectural drawings are used by architects and others for a number of purposes: to develop a design idea into a coherent proposal, to communicate ideas and concepts, to convince clients of the merits of a design, to assist a building ...

  4. Piping and instrumentation diagram - Wikipedia

    en.wikipedia.org/wiki/Piping_and_instrumentation...

    A diagram which shows the interconnection of process equipment and the instrumentation used to control the process. In the process industry, a standard set of symbols is used to prepare drawings of processes. The instrument symbols used in these drawings are generally based on International Society of Automation (ISA) Standard S5.1

  5. Engineering drawing - Wikipedia

    en.wikipedia.org/wiki/Engineering_drawing

    When part definition is defined mathematically via a solid model, the assertion that one cannot interrogate the model—the direct analog of "scaling the drawing"—becomes ridiculous; because when part definition is defined this way, it is not possible for a drawing or model to be "not to scale". A 2D pencil drawing can be inaccurately ...

  6. Block diagram - Wikipedia

    en.wikipedia.org/wiki/Block_diagram

    A block diagram is a diagram of a system in which the principal parts or functions are represented by blocks connected by lines that show the relationships of the blocks. [1] They are heavily used in engineering in hardware design , electronic design , software design , and process flow diagrams .

  7. Technical drawing tool - Wikipedia

    en.wikipedia.org/wiki/Technical_drawing_tool

    For example, the architect templates can be used to draw different sized doors with their "opening arcs", building and equipment symbols and furniture. The templates also provide the symbols for thermal insulation. A geometry template is a piece of clear plastic with cut-out shapes and/or curves for use mainly by primary and secondary school ...

  8. Embedded instrumentation - Wikipedia

    en.wikipedia.org/wiki/Embedded_Instrumentation

    The actual embedded instruments could be developed by any of several different types of groups, including chip suppliers, third-party providers, chip design tool vendors or in-house design groups. The availability of chips that conform to the IEEE 1687 standard would encourage the development of standards-based tools for interacting with and ...

  9. Axonometric projection - Wikipedia

    en.wikipedia.org/wiki/Axonometric_projection

    Classification of Axonometric projection and some 3D projections "Axonometry" means "to measure along the axes". In German literature, axonometry is based on Pohlke's theorem, such that the scope of axonometric projection could encompass every type of parallel projection, including not only orthographic projection (and multiview projection), but also oblique projection.
