Placing and editing components
X and Y The X and Y text boxes contain the coordinates of the component’s
origin, relative to the board’s (0, 0) origin. The coordinates are displayed in the units
of measurement (mils, inches, microns, millimeters, or centimeters) that you selected
in the System Settings dialog box (available when you choose System Settings from
the Options menu).
Rotation The rotation of a component can be specified in degrees (0 to 360) and
minutes (0 to 60) of rotation from the origin of the component’s associated footprint.
If you type an integer without a suffix, Layout assumes it is in degrees. If you type
two integers separated by a space, Layout assumes the second integer to be minutes
of rotation. A single quote is optional, to indicate that the second integer represents
minutes.

Tip If you are going to be rotating many components at odd angles, you can use
the Increment text box in the System Settings dialog box (accessed by choosing
System Settings from the Options menu) to set the rotation increment globally, so
that you can use the Rotate command on the pop-up menu to rotate components.
Group # A group number (0 to 100) is a permanent way of organizing
components and helping Layout recognize which components should be grouped
together, regardless of the phase of the design process. Typically, the component
group number comes directly from the schematic input.
Cluster ID Assigns the reference designator of the key component in a cluster as
the cluster name for easy reference.
Fixed Fixed components are permanently placed in a given location. The fixed
designation can only be overridden by selecting the fixed component on the board,
opening the Edit Component dialog box, and deselecting the Fixed option.
Non-Electric A non-electrical component is a component that does not display
on the schematic. If a component, such as a mounting hole, displays on the board but
not on the schematic, and you do not want the component to be deleted when you
run AutoECO, you must designate it as Non-Electric.
Locked Locked components are temporarily placed in a given location. The
locked designation can be overridden by selecting the locked component, then
choosing the OK button when a dialog box with the message “One or more
components locked. Override?” displays. You can also override the locked
designation by selecting the locked component, opening the Edit Component dialog
box, and deselecting the Locked option.
Route Enabled
If selected, tracks can be routed out of the component.
Key Assigns a key component around which other associated components are
placed.
Do Not Rename Prevents the component from being renamed when you run the
Rename Components command.
