Back Annotation of references

guess one could write something that would allow Eagle to also do that.

But I am not that great of a SW writer.

 

The ULP cmd-renumber.ulp renumbers components on the PCB in a logical order,

and if the schematic is open, back annotation happens automatically.

 

Am I misunderstanding the original request?

 

 

yeah, isn't this what I wrote? afaik if the schematic and board are

opened together back annotation is automatic, you don't have to do

anything special, but both need to be open at the same time. so when you

run the ulp it will reassign the component names in order on the board,

and the schematic will sync to that as well.

I was just confused by your use of the term "reference designator" for

what EAGLE calls "part names". I assumed that you knew what ULP's are

for and how to use them. If you don't know, they are extensions to EAGLE

that manipulate the board. Usually the renumber ulp's ( they are several

) will ask you what scheme to use such as start number, horizontal and

vertical stripes, etc. you just run it from the board window and it

should b/a automatically as long as schematic is open.

and why are you lecturing me on the need to order the components on the

board? i never said that was a problem, i just never heard of "reference

designator" before and was wondering if it referred to the board

coordinates that are sometimes printed in the drawing frame to assist in

locating components or to the component names.

sorry to confuse you.
