For future reference this was a hidden component that could not be selected for some reason. I did a text search on the PCB file and found a large positive fractional X component value. To fix this I edited the schematic to remove the component, updated the PCB to remove it then replaced the part in the schematic and updated the PCB again. You can't text edit the PCB file because it probably has some form of CRC protection.
Thanks to all. Regards, Dave -----Original Message----- From: H. Selfridge [mailto:[EMAIL PROTECTED] Sent: 03 September 2004 02:08 To: Protel EDA Forum Subject: Re: [PEDA] v large pcb document The "bounding rectangle" is supposed to be the board outline. If there are primitives out of bounds, Protel will extend the "bounding rectangle" to include them - even if they are outside the actual board outline. At this point, you best bet appears to be select, copy, and paste into a new document. If the offending part is a component designator or description that extends into negative coordinates, the copy will have the same problem. Take a look at the ASCII file with a text editor, and see if you find any negative or extremely large x or y coordinates. At 03:23 PM 9/2/04, you wrote: >Another interesting idea.
