Using leading zero's in part numbering

So, I'm able to change the name of the components. Using ULP's I can

renumber all components, even choose the starting number etc...

 

Is is possible to get leading zero's in components names?

An example: in the situation at this moment, components are numered like

this: R1, R2,.... R10, R11,  R101, R01, etc. I would like to have them

numered like this: R001, R002,... R010, R011,... R101,...

 

Why? Because when exporting the component lists to spreadsheats, it's far

more easy to sort them when they are numbered with leading zero's.

Otherwise you have them sorted in the strange way like this: R1, R10,

R101, R11, R2,...

The NAME command/icon works just fine for this. It will happily rename R1 to

R001 and so on.

That said, I prefer to renumber components by page number (R100 is on page

1, C530 on page 5, etc) Still sorts fine. Or for the freeware editions,

number components so related components in circuit function blocks have

related numbers. Nobody says the numbers have to be contiguous.

Thanks for your reply.

I didn't know that this would work, but it implies manual naming of the components. I had hoped to get this automatically.

When drawing my circuit: first I place all components, nets, without paying attention to the component names. Then, when the circuit is finished, I use one of the few renumbering-components routines in the (downloadable) "user language programs", but all these don't us leading zero's.

Now, It's nice to know I can get my leading zero's by manually changing the names (twice). Yes, twice, because you cannot change a name from C1 to C01: then you get the message that this name already exists, so you first have to rename to another non-existing name and then to the leading-zero-name. Automatically renaming to intermediate names before manually renaming to the right names could be an alternative, but then you have to manually rename all components, not only the ones you want to give leading zero's.

Until now I always used automatic numbering, starting from 10 (if there are less than 90 components of the same type on a page) or 100, but this is not my 'preferred' way: I't s bit silly to have you IC's numbered U10, U11, U12, U13 when there are only four of them on a one-page-circuit. I know, this is only a minor detail and the names are there for reference only, but I would be nice to have the option in the ULP's dialog window to enter the minimum number of digits when automatically (re-)numbering components.

Paul,

Look at renumber_sheet.sch.  It's included with 6.2.  It will do exactly

what you're requesting.

Read the usage comments at the top of the file.

Enjoy,

Thank you for replying, Chuck.

I have tested this ULP: renumber_sheet.ulp (ulp-version 4.4.0).  But I don't succeed in renumbering automatically with component names looking as follows: R01, R02,... C01, C02,...

I do succeed in renaming them in R1, R2, R3,...

Or also in R101, R102, R103,... also works.

How are you doing this?

Well... I'm not.  I just ran across this while researching an answer to

your problem.

However, using a plain text editor, look at line 179.  It contains:

      sprintf(NewNames[i[n]], "%s%d", NewNames[i[n]], ++k);

Change the "%s%d" to "%s%02d" to get 2-digit numbering, or to "%s%03d"

to get 3-digit numbering.

With a little creative programming, you could add a parameter or two to

a dialog box and generate this format string on the fly.

Hope this helps

You're the man, Chuck.

Thanks for what you do here on the forums.

Thank you very much, Chuck.

By adapting this line in the ULP, I get what I want.

In the first run I got some upcoming dialogs (almost for every component): R01 already exixts, R02, already exists,... but I used another ULP (renumber-sch-group_v2) to first rename them to another number-region (f.e. starting at R501) and after that it ran flawless.

By the way, I always use the ULP: "renumber-sch-group_v2.ulp" because it has some more options. Your tip is also working for this ULP (line 167).
