Hi George,
Thanks for the tips! I did note that the copy/paste was NOT "windows
standard". I didn't know what to expect with CUT. After reading your post
(and the manual AGAIN), I've since made it through one variation of a part.
I wasn't clicking on the origin with the CUT.
The copy/paste (cut/paste?) was not very intuitive, that's for sure. I
think after a few more times I'll have their way down.
True, I really don't need to change much of a part, but these VCC vs. VDD
conflicts were killing me.
I already had a lovely schematic drawn in Orcad Capture. I've sense read
that I may be able to import a net list (undoubtedly modified for Eagle)
into the layout. That should be interesting.
I gather that I SHOULDN'T try to route or auto-route until the schematic is
finished and the "Electrical Rule Check" finds no errors. I can rip-up
segments of traces, but not the entire design, apparently.
Sounds like some very interesting things can be done with scripts and ULP's.
Now if I could get Orcad to import something (EDIF and PDIF, whatever THEY
are)!
I just bought the lowest level of Eagle, with the same functionality as the
free Light version. My project just fits. I'm considering going to the
next level, but I'd like to do it gradually, one "package" at a time. Does
that work? Does it make sense?
