BOM item settings |
Scroll |
The item settings affect its position and display in the BOM and set the rules for processing the item when certain commands are executed. Elements presented in the table are used to manage settings BOM item settings controls (see also Figure).
Section/element |
Description |
|
Info |
A section containing general information about the selected BOM item. |
|
Type |
This reference field displays the type of row highlighted in the BOM table: •Base BOM Object (see section Base item, •Auxiliary BOM Object (see section Auxiliary object), •Name of BOM Section (see section Headers of sections and section blocks, •Empty Row (see section Empty rows), •Reserved Text Line (see Section Reserved Lines, •Block Beginning (see sections Version blocks, Section blocks, •Workpiece object (see section Object-blank, •Common name (see section General name). |
|
Section |
This reference field displays the name of the current BOM section. |
|
Section for selecting the subsection that includes the BOM object. Is present on the Parameter Panel if configuring specifications for the current section. Division into subsections enabled. |
||
Subsection name Subsection number |
These fields are used to move an item to another subsection within the section where it is located. The values in the fields are interrelated: when you select the name of a subsection from the list, the number of this subsection appears in the adjacent field and vice versa, after specifying the number, you can see the name of the corresponding subsection. As a result of selecting another subsection, the position of the item in the section may change. If the current section has no subsections, then the lists of names and numbers of subsections are empty. In this case, you can create a subsection in the section by specifying its number. |
|
Object Settings |
A section containing controls for managing the 'behavior' and display of a specification object. |
|
Ref.No increases |
Using this option you can specify whether the reference number of this item should be the reference number of the previous item plus 1. |
|
Show Position |
This option enables or disables the display of the reference number of the BOM item in the table. |
|
Version Object |
This option is automatically enabled for objects formed by the Add Object Instances command (see section Creating versions of BOM items). The effect of this option is significant only when you create a group BOM with more than ten versions (see section Type B group BOM). The active option means that when presenting information items in the BOM, the relevant item should not be separated from its source item. The source item shall be the first previous item with the same designation that has no Version Object attribute. Besides, for items with this attribute enabled, the Add Versions command is unavailable (that is, it is impossible to create a version of a version item). |
|
|
The combination of options Ref.No increases, Show Position and Version Object controls the "behavior" of the item during automatic positioning and sorting of items. |
|
By Default |
This link appears in the Parameter Toolbar if the user changes the state of one or several options from the list above that were automatically configured when creating the BOM item. It is used for resetting to automatically configured settings. |
|
Group |
This option defines ability to group an object with its "twins". •The enabled option means that object grouping is allowed. Such an object, upon the appearance of “duplicates”, is grouped with them. Each group takes one row in specification view. •Disabling the option means that grouping of the item is prohibited. Object with disabled option always occupies a separate row in specification view, even if it has one or more clones. |
|
From New Sheet |
This option allows placing the selected item or section header on a new BOM sheet. The option is not available if the BOM is placed on the drawing sheet. |
The state of options Ref.No increases, Show position and Version Object is set for each object at the moment of its creation. The settings depend on the item creation methods and item properties.
Due to this, all items behave in a way that corresponds to their characteristics when sorting, setting positions, and splitting a BOM with a large number of versions into blocks.
Let’s look at a few examples of an automatically generated combination of the base item settings. In these examples, it is assumed that the positioning in BOM sections is allowed (enabled).
•The item was created using the Insert — Add base item command (see section Adding BOM section and item). Its text part in the column used for sorting differs from the texts in this column for other section items.
For example, in the Parts section, an item was created with the designation that differs from the designations of other parts (already existing in the BOM).
At the time when the item creation is confirmed, the system automatically sorts in the current section: compares all texts in the column Designations, which is used for sorting. After checking that the designation of a new item is unique (that is, there is no such part in the BOM yet), the system activates the Ref.No increases option for the item. This means that the item will have its own unique reference number. The option Show position is also enabled (the system has no reason to automatically hide the reference number of a unique BOM item).
Thus, each time you create positions, a new object will receive a reference number which differs from the reference number of previously numbered item.
•The item was created using the Insert — Execution command (see section Creating versions of BOM items).
Regardless of whether the display of only the version number or full designation is enabled, the full designation is stored inside the item. Immediately after the item creation the sorting will occur, and in accordance with this designation the item will be placed immediately after the source item, which has the same designation but without a suffix. The option Version Object — is enabled for the object — due to this the object 'remembers' its full designation.
The need to assign a new reference number to the version item and to display this position in the table are case-specific. For example, if different versions of the same part are used in the same assembly unit, then in the column Position of the corresponding BOM items, different numbers should be displayed.
If different versions of the parts are used in different versions of the assembly unit, then in the group BOM they should have the same reference number, which is displayed only for the main version.
The BOM can use both ways of version items numbering.
•If the BOM settings If the option Positions Ascend is disabled, then when creating execution objects, options Ref.No increases and Show position are also disabled. As a result, version items are not numbered, and the next item has the reference number equal to the position number of the source item for which the versions were formed plus 1.
•If the to the BOM settings If the option Positions are ascending is enabled, then when creating versioned objects, the options Ref.No increases and Show position are included. As a result, version items will be numbered in the ascending order.
|
If the version item is the first item of the section, i.e. there is no base item or another version with the same designation above it, then the position of such item is shown in the table regardless of the state of the Show Position option. |
|
The Set Ref.Nos. button on the Section panel controls the display of reference numbers for all items in the section. When you press this button, a request to clear positions for already created objects is shown. You can confirm or cancel clearing, in the latter case all the objects in the section will retain currently assigned positions. However, all items created after disabling the Set Ref.Nos. button will not be numbered. |
|
It should be understood that the disabling of position display for objects differs from disabling reordering of positions. If positioning is enabled for the section, but the display of positions for any items is disabled, then reference numbers will be assigned to such items of the section during automatic positioning; and although these numbers will not be visible in the table (since the display of positions is disabled), the subsequent items will be numbered with regard to the assigned reference numbers. If positioning is disabled for the section, then regardless of whether the display of positions is enabled or not, and regardless of whether the Position column is populated for any items of the section or not, the reference numbers in the next section will not take into account the items and reserved rows of this section. |
