They differ from a Standard component in that connectivity created by copper within the footprint is not checked it is this copper that allows the nets to be shorted.
Standard - components that possess standard electrical properties, are always synchronized between the schematic and PCB (the footprint, pins/pads, and net assignments must all match), and are included in the BOM.Type - Select one of the following component types for the component footprint here.Description - the component/part description.Use the drop-down to select the number of the associated part then enter the total number of parts. Part of Parts - displays the number of the selected part and the total number of parts.Toggle the eye icon to show/hide the name. Use the lock icon to lock/unlock the name. Use the lock icon to lock/unlock the designator. Toggle the eye icon to show/hide the designator.
Post-placement settings – all Part object properties are available for editing in the Properties panel when a placed Part is selected in the design space. Select the object in the Primitive List to reveal its options on the right. Pre-placement settings – most Part object properties, or those that can logically be pre-defined, are available as editable default settings on the Schematic - Defaults page of the Preferences dialog (access from the button at the top-right of the design space). The property settings for each type of object are defined in two different ways: Schematic Editor object properties are definable options that specify the visual style, content, and behavior of the placed object.
