Assembly Drawing
An assembly drawing is a technical illustration that shows how various parts and components fit together to create a complete product or structure. It provides a visual guide for assembling the individual parts and often includes labels, part numbers, and other relevant information to aid in the construction process. These drawings are commonly used in manufacturing and engineering to communicate the assembly process.

...Chapter 11 Assembly Drawings DOI: 10.1201/9781003001386-11 Few engineering items are completely functional on their own. There are some, a spanner or a rule for instance, but even a simple object like a wood chisel has three components, and a good pair of compasses may have 12 component parts. Each part should be drawn and dimensioned separately, and then a drawing is made of all the component parts put together. This is called an ‘Assembly Drawing’. 11.1 INTRODUCTION Engineering drawings play a crucial role in product development since they help us communicate, visualise and document a design. However, drawings alone will not fully describe a product. Nowadays, 3D CAD models, reports, calculation sheets, change orders, etc., are part of the product documentation. Nevertheless, a working drawing is one of the most important documents since it fully describes a product’s shape and size and specifies the manufacture and assembly of the components. A set of working drawings usually comprises detail drawings, i.e. multi-view drawings of single parts which specify the part’s geometry, material, surface finish and sometimes even manufacturing steps. In case of assemblies, one or more Assembly Drawings are additionally required to show the relative position and orientation of the parts and how they interact. The number and type of Assembly Drawings depend on the complexity of the product and therefore on its product structure. An assembly can consist of components which are grouped together to a subassembly but also of single parts. In Figure 11.1, a product structure is given. On the uppermost level the product consists of two assemblies and two single parts. The assemblies on their part comprise single parts and subassemblies...

...The emphasis is on the true dimensions of structural materials to be used in the build, and on construction methods including joinery techniques. These drawings are typically produced with Computer Aided Design (CAD) programs. Structural information will include drawings for mechanical and engineered parts. Such drawings also define assembly methods with particular attention to the hardware used when applied to stage fixings. Detail drawings and the engineer A detail drawing is generally at a larger scale than the layout drawing. For construction purposes a cross section drawing will be included, defining the details as component parts. The term ‘engineering drawings’ applies to industrial modification of technical ideas. These specific and highly detailed drawings are accurate and precise for the manufacture of engineered components. The graphic language of engineering drawings is very specific. Complex scenic units that engineers design on behalf of set designers include mechanisms for movement such as: revolve, hydraulics, pneumatics, or where power control is required or where motion control functionality is needed. Venue drawings: the theatre ground plan and theatre section Theatre or venue technical drawings define the architecture of the performance venue. This consists of two drawings: ‘theatre ground plan’ and ‘theatre section’. Each defines the architectural relationship of auditorium seating to on-stage and off-stage areas. Off-stage areas may include wing space, dock area for scenic storage, get-in facilities such as dock doors, lifts, actor entrances from dressing rooms or as cross-over behind or under the stage, and access to sub-stage including orchestra pit. The amount of technical detail included on a theatre ground plan or theatre section can be significant, often making them complex maps to read...

...The type of drawing concerned is of a preliminary nature and subject to much modification so that the designer can collect his thoughts together. The drawing can be true to scale or possibly be enlarged or reduced in scale depending on the size of the finished product or scheme, and is essentially a planning exercise. This is useful in order to discuss proposals with prospective customers or design teams at a time when the final product is by no means certain, and should be regarded as part of the design process. Provisional layout drawings may also be prepared for use with tenders for proposed work where the detailed design will be performed at a later date when a contract has been negotiated, the company being confident that it can ultimately design and manufacture the end product. This confidence will be due to experience gained in completing similar schemes undertaken previously. Combined Detail and Assembly Drawings It is sometimes convenient to illustrate details with their Assembly Drawing on the same sheet. This practice is particularly suited to small ‘one-off’ or limited-production-run assemblies. It not only reduces the actual number of drawings, but also the drawing-office time spent in scheduling and printing. Figure 9.5 shows a simple application of an assembly of this type. FIGURE 9.5 Combined detail and Assembly Drawing of hub-puller. Exploded Assembly Drawings Figure 9.6 shows a typical exploded Assembly Drawing; these drawings are prepared to assist in the correct understanding of the various component positions in an assembly. Generally a pictorial type of projection is used, so that each part will be shown in three dimensions. Exploded views are invaluable when undertaking servicing and maintenance work on all forms of plant and appliances. Car manuals and do-it-yourself assembly kits use such drawings, and these are easily understood...

...Only information relating to the assembly is included on the drawing such as fitting instructions or dimensions that must be adhered to are allowed on this type of drawing. 2.2.5 Combined Drawing In some cases this may be drawn as a combined part and Assembly Drawing together with all the manufacturing details and a tabulated parts list. This type of drawing is restricted to fairly simple type of drawings. 2.2.6 Arrangement Drawing This type of drawing shows the arrangement of assemblies and parts. It should include important information as well as performance requirement features. An installation drawing is a particular variation of an arrangement drawing that provides the necessary details to affect installation of the associated equipment. 2.2.7 Diagram Drawing This is a drawing that depicts the function of a system, typically electrical, electronic, hydraulic or pneumatic schemes. 2.2.8 Items List (Also Referred to as a Parts List) An item list is a list that includes all the component parts that make up the assembly. An item list will either be included on an Assembly Drawing or as a separate drawing that the Assembly Drawing refers to. 2.2.9 Drawing List This type of list is used when a variety of parts make up an assembly and each separate part or component is detailed on a separate drawing. All the drawings and items list will be cross-referenced on a drawing list. 2.3 Drawing Sheet Sizes Engineering drawings are prepared on standard-size drawing sheets. The current sheet sizes are based on the ISO sheet sizes, as detailed in Table 2.1 ranging from A0 down to A5...

Design layout drawings Most original designs are planned in the drawing office where existing or known information is collected and used to prepare a provisional layout drawing before further detailed design work can proceed.
