Field Code to link to AutoCAD Table Cell

[alan_rackham]

Hi

Is there any way of writing a field code that will link to a cell?  I have managed to do this using the formula cell option, however, this will only display numbers, but not text.  Does anyone have another way of doing this?

Thanks,

It's not possible to get table cell text contents. Formula fields works only with numbers.

There are some third party paid apps out there.

As a workaround, how about linking content on the opposite way:

1. Create a Mtext with some dummy text content.

2. Insert a Field nested inside cell table.

3. Double-click the previous Field.

4. In "Field names" select "Object".

5. Click the "Select object" button and select the dummy Mtext.

6. Select the "Content" property and hit OK.

Thanks, fatal.error

My data is coming from Excel.  So working the other way does not work for me

Thanks,

This is still a problem not sure why you are congratulating me 🙂

You are correct. You can only do it for numbers using a formula. Text strings are not supported.

Hi

I am now thinking if I can get the table into a lisp list I can access this with field codes.  I found this:-

;:Ranjit Singh
;;8/3/17
(defun c:somefunc  (/ c ctr dat etdata ind lst prefix r tab tblent tblobj val varname)
 (setq etdata (entget (setq tblent (car (entsel "\nSelect table object: "))))
       ind    (cdr (assoc 91 etdata))
       tab    (cdr (assoc 92 etdata))
       r      0
       c      0
       ctr    1
       prefix "var"
       tblobj (vlax-ename->vla-object tblent))
 (while (< c tab)
  (while (< r ind)
   (set (setq varname (read (strcat prefix (itoa ctr))))
        (progn (setq val (vlax-invoke tblobj 'getcellvalue r c)
                     val (if (= 'str (type val))
                          (substr val (- (1+ (strlen val)) (vl-position (ascii ";") (reverse (vl-string->list val)))))
                          val))))
   (setq lst (cons (setq dat (cons varname val)) lst))
   (setq ctr (if (listp (cdr dat))
              ctr
              (1+ ctr))
         r   (1+ r)))
  (setq r 0
        c (1+ c)))
 (vl-remove-if '(lambda (x) (listp (cdr x))) (reverse lst)))

This helps however I want to modify this lisp to just give me the values and change the "VAL1" to "A1" etc.  Can anyone help?

Vanilla Cad objects are 'dumb' and what you need are 'smart' objects. Think of an old flip phone where a text required you to press the 3-key three times for F, the 4-key twice for H, etc., etc. Those phones were dumb. Now phones have keyboards, gps, cameras and internet access. They're smart.

You might be able to send a text on an old phone just as fast as using a new phone if you practice pressing keys really fast. But no matter how fast you press, it's still a dumb phone. If you're serious and want to use smart objects, i.e. object data and databases, you'll need to level up.

Not sure what you are trying to get at here or how it helps?
