To all,
I will second that rule to do the preview. I was in a situation where IF had
I done it I would have realized what it did to me before I just went on fat
dump an happy making changes to an existing design. The 99SE synchronizer
works very well. I have completed many designs now (being a newcommer) with
no problems other than like above self induced. I do however agree with the
person
talking about how Protel updates board and schematic from library, it is a
little less than I had hoped for in my setup. I really wish the footprints
would REALLY update all symbols from the library.
It does but it will not use those new footprints on a board you need to go
into th eschematic for each
unique part and force it to that new footprint. ie if you get properties of
the symbol you see
a pulldowm menu for footprint which now does contain the new part too BUT
until you select the
new footprint you will still see the old footprint on the board.
