The order of items in the BOM is determined by the standard. The standard also provides for grouping items into sections and defines the order of sections.
Sections are one of the BOM style components (see section BOM style). The number, titles and order of sections are set in the style setting. By choosing the style of the current BOM, you thereby choose the list of possible sections of the BOM among other settings and parameters.
Before adding an item, you can select or create a section for its placement.
You cannot move an item from one section to another.
|
Moving between sections is impossible for items in a BOM that is not related to the document. If a document is connected to the BOM, then the objects in it are automatically generated based on the properties of the constituent parts of the product obtained from the document. In this case, the belonging of an object to a particular section of the BOM is determined by the value of the BOM section Constituent part. |
BOM sections cannot exist without items. Therefore, when a new section is created, the first item immediately appears in it, and when the last item is deleted from the section, the section is also deleted.
You can delete a section only by successively deleting all the items in it.
A section whose item is currently selected or edited is considered the current section.
A distinguishing feature of KOMPAS–3D BOM is the ability to create and fill sections in an arbitrary order. The system will automatically arrange the resulting sections in the standard sequence (in general, in the sequence defined when setting the BOM style). Each new section will be placed in a place strictly defined in relation to the existing sections, if necessary, the pre–filled lines will be "pushed apart".
For example, you can first enter the standard items, then create and fill in the Documentation section, go to the input of parts, and then to the assembly units. Assembly units will be automatically placed between the Documentation and Parts.
Examples of specification sections are shown in the figure. Section headers, empty and reserved lines.
The BOM may contain nested and additional sections.
Nested sections are located inside the section, after all the items in this section.
Additional sections are located at the end of the BOM, after all its sections. Usually, additional sections are located starting with a new sheet.
Groups of nested and additional sections are called, respectively, blocks of nested sections and blocks of additional sections.
For example, in the Kits section of a simple BOM according to GOST R 2.106–2019, the following blocks of nested sections may be included:
•Assembly kit,
•Replacement parts kit,
•Spare parts kit,
•Tool and accessories kit
•Stacking kit.
An example of a BOM with additional sections is the BOM made in accordance with GOST 2.413–72 "Rules for making the design documentation of products manufactured with the use of electric mounting". Such BOM may contain one of the following blocks of additional sections:
•Set to XXXX.XXXXXX.XXXME,
•Set to XXXX.XXXXXX.XXXTB,
•Set during electrical wiring.
Using blocks in the specification Establish by... implies Indication of document (usually an electrical drawing or connection diagram), the designation of which is automatically inserted into the block of sections header.
Additional and nested sections in KOMPAS–3D BOMs can only be sections similar to the main, non–nested and non–additional, sections. The settings of the additional and nested sections should coincide with the settings of the corresponding main sections. Usually, the following are used as additional and nested sections:
•Assembly Units,
•Parts,
•Standard items,
•Other items,
•Materials.
Blocks of additional and nested sections and lists of sections included in them are the components of the BOM style.
Numbering of items in the BOM with nested or additional blocks shall be the continuous numbering.
Headers of sections and section blocks
As a rule, the name of each section or block of sections of a BOM is placed on a separate line (or several lines) at the start of a section or block. These lines are called section headers and block headers accordingly. Empty rows are automatically added above and below the header. For example, headers of sections with empty rows are shown in the figure. Section headers, empty and reserved lines.
The BOM can be Settings so that section headers (including additional and nested) and/or empty rows around them are not displayed on its form.
