Q - question

How to check if a dimension is associative or not? (LISP)

A - answer Using the following LISP function you can verify whether the given dimension entity is associative or disassociated. The function returns nil or the number of the associative point.

; returns nil or assoc point number (1, 2, 3=both)
(defun isDimAssoc? (diment / elst dict)
 (and
  (setq elst (entget diment))
  (setq dict (cdr (assoc 360 elst)))
  (setq elst (entget dict))
  (setq elst (entget (cdr (assoc 360 elst))))
 )
 (cdr (assoc 90 elst))
)

Use this function e.g. this way:

(isdimassoc? (car (entsel "\nPick the dimension to check associativity: ")))
