PCB Object Types

AI Tools

The PCB layout editor workspace is organized as a tree and each object in that tree is of a specific type that defines its function.

These object types can be used as part of the selector in Selector-Based Layout Rules.

Object Types

Syntax	Meaning	What it selects
`root`	The topmost level of the tree	The root object
`layout`	Defines a PCB board	Any layout object
`element`	Defines a component and is linked to its equivalent in the Schematic	Any sub-layouts that have a corresponding schematic element. Please note that there is one special case: `pad` could also be an `element` because it could be associated with a Terminal

Essentially folders which contain other object types. Either created and managed by the system or by the user.

Syntax	Meaning	What it selects
`container`	A system-specific object type that helps organize the tree in the app. It cannot be altered by the user	Any system object, such as the "Components" or "Nets" containers
`group`	Similar to the `container` type but is instead user defined	Any group object
`footprint`	Defines the actual footprint of a component	Any footprint object
`model`	Used to represent 2D or 3D models	Any 2D/3D models
`net`	A system-specific object type similar to `container` which organizes related `trace` objects into one place.	Any Net object. Since a `net` object is also a system object, it also will be selected by the `container` selector.
