Classification

Each classification tree represents the structure according to which the data is organized.

Attributes must be defined for the category and subcategory to describe the various properties associated with it. Each subcategory inherits the properties of the parent categories.

A classified object belongs to a specific group of objects with very specific attributes that distinguish this group from other groups.

For example, when engineers look for a bolt and a bearing, the properties they look for are different, because a bolt and a bearing have different usage in the assembly.

Only leaf categories can have objects linked to them. A specific object (also termed an Instance) is classified by associating it with a leaf category and assigning the specific values for its attributes.

Example: Two Categories are created for Item, EDA Components and Capacitors. Capacitors is the child category of EDA Components.

All the attributes created at the parent level are inherited by all the child attributes.

The Manufacturer, Package and Symbol attributes are inherited by Capacitors. These are indicated by ‘P’ in the first column of the Grid.

Capacitors can have own attributes. For example, Normal Voltage and Tolerance.

After the categories and attributes are defined, these can be used while creating Items or updating the existing Items. Refer to User Guide / Online help for complete functionality. Document Category Tree and Attributes can be created similarly.

Categories and category attributes

Category management allows users to search for objects by adding categories and category attributes to the objects.

Category management allows designed parts, standard part, and documents to be grouped by common attributes and retrieved for reuse, using the attributes and their values. Classification can be defined with levels.

The classification mechanism controls a tree of categories and subcategories for the Item, Document Object types. After the categories and attributes are defined, these can be used while creating Items or updating the existing Items.

Note: Ensure that a Mask is defined for Category ID before creating a Category Tree and attributes.
