Modifying Block Linear Parameter Properties (not values)

[seawind]

Is there a way to modify a dxf code of a BlockLinearParameter

modified Lee's function LM:getvisibilityparametername to :

(defun LM:getDnmcprmtrlst ( blk par / lst) ;"BLOCKLINEARPARAMETER" "BLOCKVISIBILITYPARAMETER""ACAD_EVALUATION_GRAPH"
        (if     (and    (vlax-property-available-p (setq blk (if (= 'ENAME (type blk)) (vlax-ename->vla-object blk) blk)) 'effectivename)
                        (setq blk (vla-item(vla-get-blocks (vla-get-document blk))(vla-get-effectivename blk)))
                        (= :vlax-true (vla-get-isdynamicblock blk))
                        (= :vlax-true (vla-get-hasextensiondictionary blk))
                )
                (setq lst       (vl-remove-if ''((x)(eq x nil)) (mapcar ''((pair)(if    (and    (= 360 (car pair))
                                                                                                (= par (cdr(assoc 0 (entget(cdr pair)))))
                                                                                        )
                                                                                        (cdr pair)
                                                                                 )
                                                                          )
                                                                          (dictsearch(vlax-vla-object->ename(vla-getextensiondictionary blk))"ACAD_ENHANCEDBLOCK")
                                                                )
                                )
                )
                (princ (strcat "\nThis Block doesnt contain " par))
        )
        (if lst lst)
        (princ)
)

(LM:getDnmcprmtrlst (car(entsel)) "BLOCKLINEARPARAMETER")

(setq lst (entget(car lst))

!lst

((-1 . <Entity name: 30f5358c0b0>) (0 . "BLOCKLINEARPARAMETER") (5 . "661D63") (102 . "{ACAD_XDICTIONARY") (360 . <Entity name: 30f5358c750>) (102 . "}") (330 . <Entity name: 30f5358c0a0>) (100 . "AcDbEvalExpr") (90 . 48) (98 . 33) (99 . 329) (100 . "AcDbBlockElement") (300 . "Linear") (98 . 33) (99 . 329) (1071 . 32) (100 . "AcDbBlockParameter") (280 . 1) (281 . 0) (100 . "AcDbBlock2PtParameter") (1010 0.0 0.0 0.0) (1011 0.240209 0.549818 0.0) (170 . 4) (91 . 52) (91 . 49) (91 . 0) (91 . 0) (171 . 1) (92 . 52) (301 . "DisplacementX") (172 . 1) (93 . 52) (302 . "DisplacementY") (173 . 1) (94 . 49) (303 . "DisplacementX") (174 . 1) (95 . 49) (304 . "DisplacementY") (177 . 0) (100 . "AcDbBlockLinearParameter") (305 . "Distance1") (306 . "") (140 . 0.076861) (307 . "") (96 .  (141 . 0.6) (142 . 1.0) (143 . 0.1) (175 . 0)))

i have reached to this list

and i want to (entmod (subst (cons 96 7) (assoc 96 lst) lst)) but i get the error message : 

; error: bad DXF group: (1071 . 32)

playing with linear parameters noticed that dxf 1071 is changing value from 0 to 33 (if that can help)

 

My knowledge roofed and i need some assistance

 

dxf 96 controls the dist type and 7 is used for increment 3 for none and 8 for list

furthermore dxf 141 stores the dist increment, 142 the dist minimum and 143 dist maximum.

So when i insert a block i want to assign linear parameters with different values on all the above without the need of doing it after manually one by one

 

The general questions are :

Is there any command or a way to change those values other than the properties window ?

The above list is a DICTIONARY so we cant entmod the entrries ?

If so, how we can modify those values, via coding ?

Have a look at dynamic block functions from Lee:

https://lee-mac.com/dynamicblockfunctions.html

 

Namely LM:setdynpropvalue for changing a value of a dynamic property.
