Note: The Altium Designer SDK is currently in the Beta phase and therefore evolving along with its documentation. This reference document, derived from the Altium Designer RTL documentation, is a work in progress and includes some aspects that are different to the new SDK.

PCB Messages

Overview
The PCB Messages are messages that are broadcasted by the PCB Editor server. There are different types of messages that describe a specific action within the PCB server.
Normally the PCB message constants are used for the IPCB_ServerInterface.SendMessageToRobots method.
