Aligning Layers (Move Alignment)

Another means of alignment is by physically moving a layer or group of layers, 
again using “Object Snap” as the means of alignment.


From the Edit pull down menu, select Move.

Follow the directions that will appear in the Command Status area of the Status Bar.

Press the “W” key to select Group Mode (Note the shape of the cursor).

In this mode the cursor is used to form a window around the group to be moved. 
Place the cursor in one corner of the window and click with the LMB. 
Drag the cursor to the opposite corner and click again with the LMB. 
All selected elements will become highlighted.


Remember: 
Layers may be freely turned on or off to facilitate selection.


Commit to the selection by clicking the RMB (note the cursor shape) 

or  make a new selection as previously described.



The Command Status changes to:

Make sure the “Snap to Object” button is pressed.

Click on the Source alignment object using the LMB.


Remember the alignment object must be present in both the reference layer
and the layer to be aligned.


The Command Status changes to:

Note that a “virtual selection” box appears with the cursor at the location of the Source alignment point.


Move the cursor to the Destination alignment point and click once with the LMB. 
The “virtual selection” will snap to align with that point.
Complete the move by clicking the RMB.


Remember: 
To perform a netlist comparison, the CAM origin must be located in the same location as it is in the PCB design. Use a combination of Object Snap and Grid Snap, if necessary, to align all layers with the origin.
