Signatures on revised drawings made with AutoCAD

[bsanderson]

We have recently had a discussion on signatures on drawings created electronically. In the old days, the original drawing was signed and approved in the title block. When a revision was made, the changes were made on the same drawing so the signatures remained. Today, we make the changes in AutoCAD and print the new revised drawing on a new sheet of paper. The problem with this is that the original signatures are lost from the revised copy. I'd like to know other companies handle this.

Any suggestions would be greatly appreciated.

As I recall, the names got added into the CAD on subsequent revisions - though some kind of copy of the original rev was maintained even if only scanned/microfiche.

We also type the names after the drawing is released. The signed dwg is scanned and saved as PDF.

We have the engineer put the names in the title block for the electronic version (pdf in Windchill) of the file and then initial the blocks on the paper copies that get transmitted to the file vault. When a revision is made, the original names are left alone and all signoffs are done in the revsion block.

Thanks, everyone for the suggestions.

why not export the new or updated drawings out of autocad as pdfs and then have the approvers sign them using digital signatures in adobe reader.
This does away with keeping hard copy signed drawings all together.

I tried setting up digital signatures for engineering drawings. It seems to be more trouble than it's worth.
Every time a drawing is revised, the PDF needs to be setup for signatures. Who has time to do this every time?

No it doesn't the latest version of adobe acrobat lets you digitally sign any pdf anywhere on it.....
You simplyh click and drag a rectangle, no need for a signature field per se
