Item Numbers page (QY CAD Options dialog box)

The Item Numbers page controls whether item numbers are created in the assembly document. Once created, an Item Number column is added automatically to, and may be edited in, the assembly Occurrence Properties dialog box. The item numbers are available for display in assembly reports.

If you change an option on this page after item numbers have been created, existing item numbers are replaced when you select OK or Apply.

Maintain item numbers

Creates item numbers in the assembly. Use the options to specify the structures for which the item numbers are to be generated. Selecting OK or Apply creates the item numbers.

Item numbers are assigned in assembly order, as shown in Assembly PathFinder. New item numbers are assigned automatically as new assembly components are added.

Clearing the check box removes item numbers from the model.

See the Item numbers in assemblies help topic for a comparison of item numbering schema options listed below.

Top level only

Creates item numbers only for top-level parts and subassemblies.

Atomic - Top down

Creates item numbers for parts at all levels in the assembly structure. Subassemblies are not numbered at any level.

Exploded - Top down

Creates item numbers for all parts, subassemblies, and subassembly parts.

Items are numbered sequentially from top to bottom as viewed in the Occurrence Properties dialog box. If you create an atomic assembly report from the exploded item number structure, the numbers are not sequential.

Use level-based numbers

Displays level-based item numbers (for example, 1, 1.1, 1.2, 1.3) in exploded reports and parts lists. These are generated per owner, where:

• The top-level assembly owns parts and subassemblies.

• Each unique subassembly is an owner, and the parts and subassemblies under it receive item numbers based on its level.

Note:

To generate an exploded parts list on a drawing that uses the assembly-generated item numbers and level-based numbers, these check boxes must be selected:

• Exploded Top-down

• Use level-based numbers

Expand weldment subassemblies

Specifies whether a weldment is counted as a single item or a subassembly.

• When checked, all items within a weldment subassembly are numbered.

• When unchecked, only the weldment subassembly receives an item number. Items within the subassembly are not numbered.

Start with item number

Specifies the first number to use when item numbers are assigned in the assembly. You can enter any integer greater than or equal to zero.

Increment by

Specifies a positive integer as the item number increment value.

Item Numbers controlled by

In the Teamcenter-managed environment, displays the application responsible for Item Number generation. The value is determined by the Teamcenter preference SEEC_Synchronize_ItemNumbers. When the value is Both, item numbers are generated in the application that created the new occurrence. When the value is Tc or Teamcenter, only Teamcenter assigns Item Numbers.

Find Number generation mode

Displays the value of the Teamcenter preference PS_new_seqno_mode, and sets the mode for Find Number generation for a newly added occurrence. When the preference value is not defined, the value is set to the default value New.

Frame and Piping Uniqueness

When generating an assembly bill of material report and a parts list on an assembly drawing, these check boxes specify the criteria to use to compare individual structural frame members, pipes, and tubes to determine whether they are the same or different.

Note:

To produce the roughest calculation, similar to a total lengths parts list, do not check any boxes.

Cut length

Calculated for the final length of the frame member, pipe, or tube. If an element is nonlinear, such as a bent frame, then the path length is used to determine cut length.

Mass

Determines whether two elements are unique based on their item mass.

Miter

Uniqueness for miter cuts is based on the acute angle value (between 0 and 90 degrees).

End Angles

Determines the uniqueness of end angles for pipes and frames. Before version SE2020, this option was named Miter.

This option applies to the following properties used in the Parts List column:

• Miter Cut 1

• Miter Cut 2

• End Angle 1 (Side Face)

• End Angle 2 (Side Face)

• End Angle 1 (End Face)

• End Angle 2 (End Face)

Use Angle direction as uniqueness criteria

When checked, the uniqueness is based on the angle direction.

Tube Uniqueness

When generating an assembly bill of material report and a parts list on an assembly drawing, these check boxes specify the criteria to use to compare individual tubes to determine whether they are the same or different.

Flat length

Calculated for the flat length of the tube.

Mass

Determines whether two elements are unique based on their item mass.

Gusset Plate Uniqueness

When generating an assembly bill of material report and a parts list on an assembly drawing, these check boxes specify the criteria to use to compare individual gussets to determine whether they are the same or different.

Mass

Determines whether two elements are unique based on their item mass.

Cutting stock (bounding box) parameters

Specifies that you want to create the gusset name to include Cutting Stock parameters.

Gusset Parameters

Specifies that you want to create the gusset name to include Gusset parameters.

Naming

Displays the conventions used to create the gusset name displayed in the report.
