If the layer can not be deleted because it contains component primitives that cannot be removed, an error pop-up will appear to alert you that the action cannot be completed. Depending on how the layer is being utilized, you will come across three options: To delete a layer, you can right-click on the desired layer and select Delete Layer.

Make any changes in the Edit Layers Pair / Edit Layer dialog as needed. To edit an existing component layer pair or mechanical layer, double-click directly on its entry on the View Configuration panel (or right-click on the desired entry and choose Edit Layer from the context menu). Right-click anywhere in the Layers region of the panel to display the context menu, providing commands to Add Component Layer Pair (a pairing of two mechanical layers) and Add Mechanical Layer.Įven though older versions of Altium's PCB design software are limited to 32 mechanical layers, newer PCB files that contain more than 32 layers can be safely opened and edited in an older version. Use the button at the bottom-right of the design space then select View Configuration or press the L shortcut key to display the panel. Their display state is also configured in the panel. Mechanical layers are added, edited and removed in the View Configuration panel. These individual/layer pairs can be included in printouts or in fabrication outputs, as required. Since pairs are used for component-related detail, they are called Component Layer Pairs.

As a pair of layers, for detail such as the component courtyard, that applies to a specific side of the board.

An individual mechanical layer, being used for a task that does not apply to a specific side of the board, such as the board outline, or.

There are two ways mechanical layers can be used, either as: In Altium Designer, this type of additional information is detailed on Mechanical Layers. It might be the board dimensions or the fabrication detail, it might be the component courtyards, or it might be the 3D component models.

Transitioning from Numbered Mechanical Layers to Layer TypesĮven the simplest board needs design detail beyond the tracks and pads that implement the circuit.
