Eagle question

[mikep]

is it possible to copy and paste, or array, a layout fragment in the board editor? It seems strange that I have to arrange and route the same subcircuit 6 times, what am I missing?

thanks,
mike

thanks roger

but how do you deal with the backannotation? what Im trying to do is copy a portion of a schematic AND the layout of that portion? right now when I copy a portion of the schematic I have to go to the board editor and manually arrange those components, but I already did it once...

thankyou roger

this is what I figured out:

open the project.
close the schematic
copy sections in the layout as per roger's suggestion
open schematic (will give an "inconsistant.." error)
manually copy the same sections
run ERC to see if there are still inconsistancies, fix if needed
save schematic
close schematic
reopen schematic (now back annotation should be active)

Im not getting good results with parts that have long alphanumeric names, it increments numbers fine but for more complex stuff you also have to go and change the part names manually. is this the only way?! can't be...

The issue is how eagle deals with named elements in the schematic vs the board.
The schematic keeps the names the same, ie vss stays vss in the copy.
The board will add a number to the copy, ie vss becomes vss1

So the thing is to layout your blocks first without any naming, then add the names once you are copied and consistent again.

Another quick Question for you Eagle experts (im getting there)

what is a good way to export if I need to get the data into autocad or Solidworks? I need the dimension layer and holes to make a mechanical manufacturing drawing. when I make a .EPS file from the CAM processor and import it into Acad R14 the scale is off and I can't figure out why. the holes aren't round either and autocad can't dimension to their centers cos they arent really circles. sure would be nice if you could add dimensions within eagle.
