Field the reads total number of layouts

Is there a way to return the total number of layouts in a drawing file?

I would use it to update a field showing the total number of sheets in a set.

(eg 2 of "X", where X is the field variable).

heres one way the variable Len is the number you require

(setq doc (vla-get-activedocument (vlax-get-acad-object)))
(vlax-for lay (vla-get-Layouts doc)
 (setq plotabs (cons (vla-get-name lay) plotabs))
)

(setq len (length plotabs))

Thanks BIGAL.

I do not think that I can use this solution because I am only using LT. Is that correct?

If I break it down, does the code you provided extract a list of all the layout tab names and then count the number of items in that list?

It looks unlikely therefore that I can get a simple variable in the Field dialog box.

Didnt see the LT not sure if you can get around it smae sort of thing how many layers in a drawing theres no variable saved with the total.

Hey BIGAL, this is almost exactly what I need, however is their a way to have it subtract the MODEL tab or just less one?

Took me a while "len-1"
