How to use Diesel expression for part of file name for title block attribute

[Tyler.eurich]

Hello, 

I currently have the title blocks for the company that I work for set up with diesel expressions to use the file name for attributes for the filename and drawing number.

Our filename template is XXXXXX-ZZZEPP.DWG.

XXXXXX is the drawing

-ZZZ is the sub-assembly 

ans PP Is the sheet number (E stands for electrical)

The diesel expression I am using to get the drawing number is $(substr,$(getvar,"dwgname"),1,$(-,$(strlen,$(getvar,"dwgname")),7))

I need a diesel expression for the sheet number attribute from the file name, which would be characters 12-13 of 17 total.

Any help is appreciated

Fix filename length?

$(substr,$(getvar,dwgname),12,2)

variable length

$(substr,$(getvar,dwgname),$(-,$(strlen,$(getvar,dwgname)),2),2)
