Abstract
Multiple users simultaneously edit at least a portion of a printed circuit board (PCB) design. The PCB design portion is transmitted to first and second clients for graphical display at each of the clients. A first protection boundary is associated with an area of the PCB design being edited at the first client. A second protection boundary is associated with an area of the PCB design being edited at the second client. The first and second protection boundaries are displayed at each of the first and second clients. A request from one of the clients to edit an object within a region bounded by a protection boundary associated with the other client is rejected. The protection boundary may surround a user's cursor. The size of the boundary may increase based on editing activity by a user in an area of a PCB design.
