Occurrence properties

Occurrence Properties

This command allows to define the bom index and the properties of an occurrence of a part (or sub-assembly). This can be done manually or with a reference occurrence.

Creation stages / Use:

Choose the Modeling > Occurrence Properties... command from the drop-down menu or selected an occurrence (or a sub-assembly) of a part and then choose the Other sub menu from the contextual menu.

Mode with reference occurrence:

In the Reference occurrence field, select a reference occurrence in order to get its properties and/or its index.
In the Additional occurrences area, select one (or several) occurrence(s).
Chose one or several properties in the Properties area and then define a value of each property and/or type the value of the index.
Confirm with the button in order to apply the modifications to the reference occurrence and the additional occurrences as well.

Manual mode:

In the Additional occurrences area, select one (or several) occurrence(s) or select one occurrence in the Reference occurrence field.
Chose one or several properties in the Properties area and then define a value of each property and/or type the value of the index.
Confirm with the button in order to apply the modifications to the reference occurrence and the additional occurrences as well.

The components linked to a part are grouped together in a BOM: for example, you can apply the index 101 to all the M5x30 screws inserted into the plate with index number 100, apply the index 201 to all the M5x30 screws inserted into the plate with index number 200, etc...

Available options:

Occurence bom index :

This options allows you to grey out the field which allows to type the occurrence bom index.

Modifications / Additional information:

The index of parts indexed in this way is displayed in square brackets in the Parts folder of the Entities tree.
It is shown on a green background in the bill of material. You can change this color in the Bom page of the Tools > Options command.
An index can also be forced directly in a bill of material by selecting a part in the list and checking the Occurrence index option.

A distinction is made between Occurrence properties and parameters :

Occurrence properties are local to occurrence. The properties don't inherit from occurrence to occurrence.
Parameters are inherit from occurrence to occurrence.

Occurrence properties can be used to scrapping properties already present in the definition document. This allows you, for example, to modify the description or part number of a component included in the assembly.

They can also be modified from a Bill of Material displayed in the Parts tree, or from the Tools > Characteristics command when the occurrence properties have been set as modifiable in Tools > Options > Characteristics.
