Auto Populate Revision level based on name of the file

[AARON.RISTAU]

I am looking for some help (if possible) with auto populating the "REV #" line in the "Enhanced Attribute Editor" with the revision of the name of the file. The files always get saved as     " xxxxxx-rev. A"  ect.   Is there a way to take the revision from the name of the file and input it into the revision. It seems trivial to just add it but this ensures there are no mistakes.  see below

That attribute needs to be a FIELD: start that FIELD command name and look for what you want to point to there.

Do you want it to show just the last letter of the drawing name?  If so you can make it a field and choose DieselExpression as the field type and use $(substr,$(getvar,dwgname),$(-,$(-,$(strlen,$(getvar,"dwgname")),4),1),1) as the expression.

Yes correct just the "A" or "B" or what ever it might be

Then like I stated in my last post make it a field and choose DieselExpression as the field type and use $(substr,$(getvar,dwgname),$(-,$(-,$(strlen,$(getvar,"dwgname")),4),1),1) as the expression.

@AARON.RISTAU when in the attribute editor instead of entering text in the value right click and select Insert Field.  Then in the dialog box under Field category select All and then under Field names select DieselExpression and then on the right side paste the expression $(substr,$(getvar,dwgname),$(-,$(-,$(strlen,$(getvar,"dwgname")),4),1),1)

 Thank you for your help. I input the script into the Deisel pushed ok but nothing saves so it just comes up blank

Maybe you did something wrong. Try again and if it still doesn't work maybe you can post the drawing file here.

@ AARON.RISTAU Did you edit the attribute default in your block? Show us your step by step in a video please, this is a good free recorder from Autodesk https://knowledge.autodesk.com/community/screencast

@AARON.RISTAU   Sorry I wasn't thinking right, I messed up the expression,  I should have tested it. Try this:

 $(substr,$(getvar,dwgname),$(-,$(strlen,$(getvar,"dwgname")),4),1)

I am not sure why but I restarted my computer and it updated finally. thank you for all your help

Probably not your computer. I did the expression wrong the first time. Make sure to use the last one I posted.
