Applied Parameters: Action=CreateUnion

Summary

This command is used to create a union from the currently selected design objects. A union is a collection of objects that have been grouped together. When grouped as a union, you are able to quickly select/deselect all union members, and move them all when a single member of the union is moved.

Access

With the required design objects selected in the main workspace, this command is accessed from the Schematic Editor by choosing the Tools » Convert » Create Union from selected objects command from the main menus.

Use

First, ensure that the design objects that you wish to make part of the union, are selected in the main design workspace.

After launching the command, a union will be created, with the selected objects as its members. An information dialog will confirm how many objects were added to the union.

Tips

  1. To move all objects in a union, simply click and hold on a member object of that union, then drag the cursor to move all in that union. Do not select the member object first, otherwise only that object will be moved.
  2. If the Always Drag option is enabled, on the Schematic - Graphical Editing page of the Preferences dialog, then moving all objects in the union by clicking and dragging a member of that union, will not be possible.

Applied Parameters: Action=BreakUnion

Summary

This command is used to remove one or more member objects from a specific union. A union is a collection of objects that have been grouped together. When grouped as a union, you are able to quickly select/deselect all union members, and move them all when a single member of the union is moved.
