There are five sets of variable calculations below.

The first group minus the second group

The second group minus the third group

The fourth group minus the fifth group

Five sets of answers are written in mtext

 

 

 

 

 

(defun c:areax ()

How’s about tackling this one set at a time first to make sure you at least get what you’re looking for after selecting the first set. What do you expect this to give you for mtvalue1:

(setq i 0)
  (repeat (sslength ss1)
    (setq mtvalue1 (strcat mtvalue1
                           (itoa (vla-get-objectID (vlax-ename->vla-object (ssname ss1 i))))
                           ">%).Area \\f \"%lu2\">%+%<\\AcObjProp Object(%<\\_ObjId ")
          i        (1+ i)))

the code below to properly get the field value for mtvalue1 is the format you should follow for the other selection sets:

(setq i 0 mtvalue1 "%<\\AcExpr (")
(repeat (setq len(sslength ss1))
 (setq mtvalue1 (strcat mtvalue1 "%<\\AcObjProp Object(%<\\_ObjId " (itoa(vla-get-objectID (vlax-ename->vla-object (ssname ss1 i)))) ">%).Area \\f \"%lu2\">%") i (1+ i))
 (if(/= i len) (setq mtvalue1 (strcat mtvalue1 " + "))(setq mtvalue1 (strcat mtvalue1 ") \\f \"%lu2\">%")))
)

A little simplification you can make --

This construction, to find closed Polylines both with and without linetype generation enabled:

 

(setq ssx (ssget '((0 . "LWPOLYLINE") (-4 . "<OR") (70 . 1) (70 . 129) (-4 . "OR>"))))

 

can be replaced with this:

 

(setq ssx (ssget '((0 . "LWPOLYLINE") (-4 . "&") (70 . 1))))

 

The (-4 . "&") operates like (logand), recognizing any value in the (70) entry that contains the 1 bit indicating the Polyline is closed, whether or not the 128 bit about linetype generation is present.

check this. mtext row (1-2) (2-3)(4-5).
