Field expression from part of tabname

WesFra — Thu, 25 Nov 2021 07:56:20 GMT

Hi all, and thanks in advance for reading

I'ld like to have a field expression that references a part of a tabname, but it has a variable set of characters.

It is however divided with a "_" sign.

For instance: 001_A_variableset1_variableset2

$(substr,$(getvar,ctab),1, 3) gets "001"

$(substr,$(getvar,ctab),5, 1) gets "A"

for the variable sets i"m stuck however

any thoughts/ideas?

You can't do that with DIESEL coding. If interested we can help create a custom solution using AutoLISP or .NET as long as you have full AutoCAD.

Hi, thanks for you reply.

for such a small feature I wouldn't want to bother anyone really.

It's just small bits of text I'll just have to type twice.

But thanks though!

Not sure if this helps... it just copies the first part into the clipboard.

(vl-load-com)

(defun c:CT1 ( / en tx html) ; Copy Text To Clipboard
  
  (and (setq tx (getvar 'ctab))
       (setq tx (substr str 7 (- (vl-string-search "_" str 8) 6)))
       (princ (strcat "\n>> " tx " ... in clipboard. "))
       (vlax-invoke (vlax-get (vlax-get (setq html (vlax-create-object "htmlfile")) 'ParentWindow) 'ClipBoardData) 'setData "Text" tx)
       (vlax-release-object html)
       )
  (princ)
  )

Are you an LT user? If not, consider more capable customizations languages in AutoCAD then seek help in one or more the correct forum over here https://forums.autodesk.com/t5/autocad-customization/ct-p/AutoCADTopic1

If you are an LT user, your forum is over here https://forums.autodesk.com/t5/autocad-lt/ct-p/2000
and what you want to do may be very limited by DIESEL's limitations
