First, the assembly drawings (iso, orthos, exploded views, BOM) for the entire design should be shown with proper dims between individual components / assemblies. Next, individual part drawings for parts X and Y should be shown. After all individual parts have been shown, assembly drawings for subassembly A are shown. The same sequence outlined above is repeated for this assembly. All parts not in other assemblies are listed first, followed by their constituent subassemblies (where the same  \nordering procedure is maintained) . Notice how each subassembly is broken down immediately after it is shown before moving on to assemblies on the same level. Once everything under the tree in subassembly A has been shown, move on to subassembly B. If a part is an element of multiple subassemblies (for example if part 5 and part 12 are the same), it only needs to be shown once, in its earliest location. But, be sure to keep its item number / part name consistent in the BOM and exploded views.  \nAssembly Dimensioning Guidelines  \nWhen creating ortho drawings for assemblies, the only dims needed are those that locate individual components with respect to each other. Constituent subassemblies should be treated as if they have already been constructed. So, dimensions pertinent to the smaller assemblies do not need to be included in the larger assembly drawings. Instead, dims between that subassembly and other assemblies/components that it mates to need to be included.  \nLikewise, dims that are solely driven by the geometry of components, rather than their mating locations, are also unnecessary since they do not provide relevant information regarding the fabrication of the assembly. The overall length of the Gripper Assembly in the attached example is a good illustration of this concept. The total length is independent of how the parts fit together. The value could also easily be derived by referencing the exploded view of the assembly to determine the parts, and subsequently the respective part files (and then adding the pertinent dims) . The components can’t be assembled in a way consistent with the exploded view that results in a dimension of anything other than 17.0 inches. So, it isn’t a requisite dimension in the orthographic views. But, the overall length of the assembly could bea useful dimension to have for a variety of reasons; therefore, it is included as a reference dimension (designated by parentheses around the dimension) . Reference dims could be described by the line of thought “I don’t use this value to put the assembly together, but this is just how it turns out to be when the rest ofthe dimensions are followed”. Reference dims are used to clarify dims that provide useful information or benefit to the assembler in some way where an actual dim would over-define the drawing. Things like overall length or height are common examples of reference dims.  \nTo improve ease of assembly, it is beneficial to provide locational dims between component features that actually mate to each other. For example, if dimensioning the mounting location for a Globe motor along the length of a piece of 80/20, it would be best to dimension from one end of the 80/20 to one of the mounting holes on the motor, not to an arbitrary feature on the motor. There are, of course, exceptions to this idea, such as if you were instead mounting an Entstort drive assembly that already has a motor mount attached to the bolt pattern of the motor. If the main concern during assembly is that the edge of the mounting bracket is flush with the edge of the mob","cbCaipkix2NUcEAG","https://ap.wps.com/l/cbCaipkix2NUcEAG","pdf",356105,12,"English","# Report Organization\n## Assembly Dimensioning Guidelines","[{\"question\":\"How should assembly drawings and part drawings be ordered for a design with subassemblies?\",\"answer\":\"Show assembly drawings (iso, orthos, exploded views, BOM) for the entire design first with proper dimensions between individual components/assemblies.
