Placing components manually

There are several commands available in Layout to assist you in manually placing components on a board. You can place components one at a time or in groups. Use the Queue For Placement command to make a component or group of components available for placement based on a set of criteria (reference designator, footprint name, or first letters with wildcards), then place the components individually using the Select Next command.

To place components individually

1 Choose the component toolbar button.

2 From the pop-up menu, choose Queue For Placement. The Component Selection Criteria dialog box appears.

3 Enter the reference designator (or other criteria) of the component that you want to place in the appropriate text box, then choose the OK button. (Choose the dialog box’s Help button for information on the options in the dialog box.)

4 From the Edit menu, choose Select Next. The component snaps to the cursor. If you selected a group (such as all components beginning with the letter U), then the component with the greatest number of connections that meets the specification snaps to the cursor.

5 Drag the component to the desired location and click the left mouse button to place it.
