Aligning Layers (Layer-to-Layer Alignment) - LAB

The layers and drills have been deliberately offset.


First we’ll align layer 1 with layer 2 using Edit/Layers > Align.


Turn off all but layers 1 and 2. 
(These layers should be CAM_DemoL1.PHO and CAM_DemoL2.PHO respectively).

• CAM_DemoNC3-4.DNote the instructions in the Command Status area of the Status Bar that will assist you in stepping through this procedure.

•  Make sure the “Snap to Object” (“Z”) button is pressed on the Status Bar.

Select the lower left mounting hole on layer 2. 

Click on the object using the LMB (Left mouse button) then “Commit” to this selection by clicking the RMB (right mouse button.).

• Note how the “Page Up” and “Page Down” keys can be used to increase or decrease the “pick” area of the cursor.

• Note that layers may be freely turned on or off to facilitate selection.

Select the complimentary object on the layer to be aligned with the LMB then commit to the object with the RMB.

• Note the fact that this procedure cannot be undone. 

A warning message allows an opportunity to abort if necessary.


Clicking the RMB a second time completes the operation aligning the two layers.

Here's a demonstration of the Layer-to-Layer Alignment procedure:

Aligning Layers (Layer-to-Layer Alignment)

Once loaded, the layers and drills may not be aligned.
(For this demonstration they have been deliberately offset).

Before any meaningful analysis can be done all the elements must be aligned to each other and also to the origin.


Note: 
It is essential that the origin of the CAM350 elements match the origin of PCB design file.




Alignment can be performed in two ways. 
The first, Edit/Layers > Align…

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

Select the point on the “reference layer” to which the “offset layer” layer will be aligned. This object must be present on both layers. 

Choose a mounting hole or other prominent feature.

Note that layers may be freely turned on or off to facilitate selection.

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

Click on the object using the LMB (Left mouse button) then “Commit” to this selection by clicking the RMB (right mouse button.).

The Command Status changes to:

Select the complimentary object on the layer to be aligned with the LMB then commit to the object with the RMB.

Clicking the RMB a second time completes the operation aligning the two

layers.

Note that this procedure cannot be undone. 

A warning message allows an opportunity to abort if necessary.
