Hi,
Could there be an easier way of renaming components, please?
(I don't like the current auto-rename widget, as I can never seem to make it do what I want it to! )
One way to make the auto rename a bit more user-friendly might be to be able to specify different strip widths for the horizontal & vertical.
For my current board I want to be able to rename everything on the left hand side, then the middle, then the right; as that's how the circuit's laid out, so in effect I want three, narrow-but-tall strips.
Currently, if I want to change a component reference, I have to do several stages. For instance, if I want to swap C1 & C2 I have to call C1 C2a, rename C2 as C1 and then go back & rename C2a as C2.
I know this is to avoid the problem of duplicate names, which EPC doesn't allow to happen at all, but I can't help but think there has to be another way to do it!
Best wishes,
Olga.

Yup, that's precisely what I meant.  |

Wonderful!  Especially since this feature is in other M$ apps (Excel to name but one!)... as you say, Microsoft not doing what it should.

Anyway, until we move to a 3rd party utility for this (which is intended, but is a MAJOR project because of the global scope of the function), there's little point in asking for stuff like this. Any 3rd party utility would have to have features like this even to be considered, and if it's there, then it will be implemented!
I'm not sure how practical back annotating an actual component change would be. What about if the original only used one schematic gate, and the replacement three (or vice versa)? It wouldn't take many of thiose for the schematic to become unrecognisable with connections flying all over the place! |

Ouchie!

Yup, I see what you mean. So what we'd really want is to be able to change the component itself from that sheet (not just its value) and then back-anotate to the schematic.

Is it the 'Component Values' sheet which you're using to do this?
I've never needed a schematic which covers more than one sheet, so I've never encountered this problem. However, being able to change the reference in this sheet would be a good idea.

To Peter,
Something else which might help is the ability to sort by columns, so that you could collect all the 0.1uF together, if for example they all needed changing.

This could be coupled with a rather annoying other aspect of easy PC. At the moment, if you wish to edit the "values" of components (lets say a batch of caps need changing from 0.1uF to 0.2uF but they are spread across a number of schematic pages, you need to do them page by page. However in the PCB file ALL components are listed in order and I have said in the past that it would be great if you could edit the value there (as they are all in the one big list) and then back-annotate .... but this has never been implemented. Olgas suggestion of export/modify/import could be a good mechanism to support this problem as well

That would certainly help.
Another thing that might help is if there were a way to list all of the components in an Excel- or even text file- type manner, edit them there & then 'import' the changes to the PCB. Possibly it could be a list of current names & names you want to call them. I know that a method like this is used on another layout package, but I don't know if it would be feasible to do with EPC.

Using the component name as the index as well does have that problem.
A bigger one as far as renaming is concerned is the way we've identified symbol origins in the libraries. Surface mount is fine, as they're generally in the geometric centre, but most of the discrete items are on pin 1. Now, with a neat row of resistors, you can guarantee that at least one will have been reversed, which means that it's no longer a neat row logically, and the numbering can go haywire, especially using stripes.
