Unplacing Parts

Complete the following steps to unplace all non-locked parts:

1. Select Place»Unplace Parts. A dialog displays asking if you wish to

remove any left over copper after the unplace command.

2. Select either Yes or No. All unlocked parts are removed from the PCB

and positioned outside of the board outline.

If you chose Yes in the above dialog, the copper that was connected to

the unplaced parts is also removed. If you chose No, the copper

remains in place.

Viewing and Editing Properties

Once a shape or a part has been created, its properties can be viewed and

edited. This section explains how to display the property dialog boxes of

parts, attributes, and shapes, and what each tells you about the element.

Attributes

All properties dialog boxes for all elements have an Attributes tab. Parts

are, in general, the only elements that already have attributes, typically

including a name, a value, and a shape. For other elements, you can add

attributes. All attributes can be changed or added.

In the Attributes tab, you can change an attribute’s:

• tag (the name for the attribute)

• value (the value of the attribute)

• visibility (invisible, value shows, value and tag show).
