Re: [PEDA] v large pcb document

This is a problem that crops up regularly in all versions of Protel. It is likely that, at some point in laying out your PCB, some primitive or component accidentally has been moved or placed outside your work area. It may even be on a layer that you have turned off, such as a mechanical

Re: [PEDA] v large pcb document

Thanks for the interesting thought but I don't think that is the problem. I did check for off sheet primitives with all layers on but nothing showed up. When I select 'View | Fit Document' the board becomes a small patch at the bottom left hand corner and the coordinates of the top right are

Re: [PEDA] v large pcb document

If my memory serves me right, there is another trick here. I beleive Protel takes into account hidden comment and designator strings on the PCB when it attempts to find the boundary of your design. At least this has been my experience using Protel 99SE. The solution? If you can afford to turn on

Re: [PEDA] v large pcb document

Your symptom is exactly what is seen when a primitive, designator, note, etc. has gone off into never-never land. Often the problem is something at a negative absolute coordinate (off the bottom left corner) - Protel doesn't know what to do with negative absolutes. Yes, you can select and

Re: [PEDA] Thickest Copper

Jeff, 2 oz. However, I have a friend out in Mentor OH who's company is a contract mfg, and if my memory serves me correctly, they routinely overplate and fab to 4oz or better, as they serve the heavy industrial market (folks like CAT...) Definitely not proto quantities, however... aj

Re: [PEDA] v large pcb document

Another interesting idea. Unfortunately this does not sort the problem but it does provide a pointer to a possible solution. If I save the PCB file in PCB ASCII file format then open it again the board outline (black box with white grid) extends to the extreme right of the workspace. The DXP

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
