The following pre-packaged resource, derived from this base command, is available:


Applied Parameters: None

Summary

This command is used to access the Object Class Explorer dialog in which 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 is accessed from the PCB Editor by choosing the Design » Classes command from the main menus.

Use

After launching the command, the Object Class Explorer dialog will open. 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 (i.e. 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.
