Copying sheets from one schematic to another in V6?

e14 Contributor

Using Eagle V6.2.0 standard/Hobbyist.

 

I have a schematic that is broken into several sheets. I want to move

several of the sheets to a different schematic. As best I recall, in V5

you could group an entire sheet and CUT it, close the old schematic and

open the new one, and PASTE. Repeat for each sheet.

 

V6 has the new feature allowing merging schematics (or pasting multiple

copies of a design) without having net naming collisions. When I

CUT/PASTE schematic sheets it is renaming all the nets in the new sheet

that already exist in the schematic.

 

My problem is that nets named the same really are the same net, and I

don't want any of them renamed. The help files suggest there should be a

pop-up dialog box asking if I want nets renamed, but I'm not getting that.

 

How do I turn off the net renaming when pasting?

 

If it makes a difference, I don't have labels on all the inter-page

nets. That's in the works for my own reasons, but I'm not there yet.

    I think I've found my own answer. In V5, labels were purely for

    convenience; you could add them if and where you wanted. In V6 they have

    significance.

     

    Here are the rules for naming of components and nets when pasting:

     

    • When copying elements, signals, pads, smds and pins, a new name is

    allocated if the previous name is already used in the new drawing.

     

    • Buses retain the same names.

     

    • Nets retain the same name as long as one of the net segments has a

    label, or is connected to a supply pin. Otherwise a new name is

    generated if the previous name is already in use.

     

    The third rule above addresses my situation. If I'd finished labeling

    the inter-sheet connections before extracting pieces for layout

    experimentation I'd never have noticed the change in label significance.

     

    Hopefully this will help someone in the future.
