Default report mode:

Summary

This violation occurs when a footprint model linked to a component being defined in the Component Editor has a Pad object with no value of the Designator property specified.

Notification

A notification is displayed in the Messages panel in the following format:

Missing Pad Designator on Pad: Pad <Identifier> on <Layer>

where:

• Identifier is the identifier for the pad with no designator specified, represented by the pad net and coordinates.
• Layer is the layer on which the pad with no designator specified is placed.

Recommendation for Resolution

Specify designator values for the pads of the linked footprint model.

• In the Component Editor in its Single Component Editing mode, click the  control at the top-right of footprint's preview to open the footprint that is currently being used (referenced) by the component in the temporary PCB Footprint editor.
• In the Component Editor in its Batch Component Editing mode, right-click on the footprint entry in the Model Links region and choose the Edit command from the context menu.

The footprint model that is currently being used (referenced) by the component will open in the temporary PCB Footprint editor. Select an offending pad and specify the value of its Designator property in the Pad mode of the Properties panel.

Default report mode:

Summary

This violation occurs when a footprint model linked to a component being defined in the Component Editor has its reference point (origin) outside of the bounding rectangle formed by footprint objects.

Notification

A notification is displayed in the Messages panel in the following format:

Offset Component Origin

Recommendation for Resolution

Change the location of the reference point for it is inside the bounding rectangle formed by footprint objects.

• In the Component Editor in its Single Component Editing mode, click the  control at the top-right of footprint's preview to open the footprint that is currently being used (referenced) by the component in the temporary PCB Footprint editor.
• In the Component Editor in its Batch Component Editing mode, right-click on the footprint entry in the Model Links region and choose the Edit command from the context menu.

The footprint model that is currently being used (referenced) by the component will open in the temporary PCB Footprint editor. Use the commands of the Edit » Set Reference sub-menu of the main menus to change the current location of the footprint's reference.

Default report mode:

Summary

This violation occurs when a footprint model linked to a component being defined in the Component Editor has Pad objects which are connected with each other by objects on a copper layer.

Notification

A notification is displayed in the Messages panel in the following format:

Shorted Copper Connection Between Pad <Identifier1> on <Layer1> And Pad <Identifier2> on <Layer2>

where:

• Identifier1 is the identifier for the first instance of the pad in the shorted pad pair, represented by the net-designator pairing and pad coordinates.

A notification is displayed in the Messages panel in the following format:

Unconnected Copper on primitive : <ObjectType> <Identifier> on <Layer>

where:

• ObjectType is the type of instance of the object that is not connected to any Pad object in the footprint model.
• Identifier is the identifier for the object that is not connected to any Pad object in the footprint model; the identifier representation depends on the object type.
• Layer is the layer on which the instance of the object that is not connected to any Pad object in the footprint model is placed.

Recommendation for Resolution

Change the footprint model so the objects which are not currently connected to any Pad object in the footprint model are connected to pads.

• In the Component Editor in its Single Component Editing mode, click the  control at the top-right of footprint's preview.
• In the Component Editor in its Batch Component Editing mode, right-click on the footprint entry in the Model Links region and choose the Edit command from the context menu.
