PCB_Cmd-EditClassesEditClasses_AD

Applied Parameters: None

Summary

This command is used to access the Object Class Explorer dialog, from where you can browse, and manage, the defined object classes for the current PCB document. A class is a logical collection of a particular type of design object. For example, a group of related components could be grouped into their own Component Class which could then be used as the basis for creating a targeted design rule.

Access

This command can be accessed from the PCB Editor by:

• Choosing the Design » Classes command, from the main menus.
• Right-clicking in the design workspace and choosing the Design » Classes command, from the context menu.

Use

After launching the command, the Object Class Explorer dialog will appear. Use this dialog to define new classes, or edit/remove existing classes, with respect to each of the following supported class categories:

• Net Classes
• Component Classes
• Layer Classes
• Pad Classes
• From To Classes
• Differential Pair Classes
• Design Channel Classes
• Polygon Classes
• Structure Classes
• xSignal Classes

Tips

1. A design object of a particular type can belong to (be a member of) any number of classes defined for that object type.
2. Default (system classes) are distinguished by their names being enclosed in <>. These classes cannot be renamed, nor can they be deleted.
3. Whenever an applicable design object is created/placed in the design, it is added to the default <All> class for the respective class type.
