After the mechanical drawings are complete, they become part of the construction drawings, which is then used to apply for a building permit. They are also used to determine the price of the project. The assembly drawing typically includes three orthographic views of the system: overall dimensions, weight and mass, identification of all the components, quantities of material, supply details, list of reference drawings, and notes. Assembly drawings detail how certain component parts are assembled. An assembly drawing shows which order the product is put together, showing all the parts as if they were stretched out. This will help a welder to understand how the product will go together so he get an idea of where the weld is needed.
In detail drawings, components used to build the mechanical system are described in some detail to show that the designer’s specifications are met: relevant codes, standards, geometry, weight, mass, material, heat treatment requirements, surface texture, size tolerances, and geometric tolerances. A fabrication is made up of many different parts. A fabrication drawing has a list of parts that make up the fabrication. Line diagrams and layouts indicating basic proposals, location of main items of plant, routes of main pipes, air ducts and cable runs in such detail as to illustrate the incorporation of the engineering services within the project as a whole.
The schematic is a line diagram, not necessarily to scale, that describes interconnection of components in a system. All functional components that make up the system, i. A drawing the intended locations of plant items and service routes in such detail as to indicate the design intent. Plan layouts to a scale of at least 1:100. Plant areas to a scale of at least 1:50 and accompanied by cross-sections. The drawing don’t indicate precise positions of services, but should be feasible to install the services within the general routes indicated.
It should be possible to produce co-ordination drawings or installation drawings without major re-routing of the services. Represent pipework by single line layouts. Represent ductwork by either double or single line layouts as required to ensure that the routes indicated are feasible. Indicate on the drawing the space available for major service routing in both horizontal and vertical planes. A spatially coordinated drawing, i.
