I have not used the ROOM in protel 99SE and DXP. But when i update PCB from sch in DXP, there are many ROOMs in the PCB layout. It seems that i do not delete them because errors will be generated when update PCB. Who can explain the usages and meaning of ROOM? How can i deal with them? THX!!!
Re: What is "ROOM" in protelDXP? Can you explain i
A room is an area on the PCB where some specific design rules apply. E.g. if you have a BGA chip where you need finer traces than usual, you can make a room around it where a smaller clearance rule applies.
During forward annotation there is an option to turn schematic pages into rooms. If they bother you, just turn this option off and remove the rooms.
