adding chamfering leader

[nalsur8]

this coding only can select line not polyline

how to change the code, so user can select line and polyline to add dimension/leader

 

TQ

 

 

(defun C:DCH(/ CL CHAM DL PT1 PT2 ANG ANG1 DIST PT3 PT4 DIST1 T1 H1 V1)
 (defun *error* (msg) (setq *error* nil) (princ))
 (setq old10 (getvar "ucsorg"))
 (command "_ucs" "w")
 (command "_ucsicon" "or")
  (setvar "CMDECHO" 0)
  (setq CL(getvar "CLAYER")
        CHAM(entget(car(entsel "\nSelect Chamfer to Dimension: ")))
        PT1(cdr(assoc 10 CHAM))
        PT2(cdr(assoc 11 CHAM))
        ANG(angle PT1 PT2)
        ANG1(angtos ANG 0 0)
        DIST(distance PT1 PT2))
  (cond 
    ((or(= ANG1 "45")(= ANG1 "135")(= ANG1 "225")(= ANG1 "315"))
        (setq PT3(polar PT1 ANG (/ DIST 2.0))
              PT4(getpoint "\nNote Location: ")
              DIST1(rtos(* DIST(abs(cos ANG))) 2 2)
              T1(strcat "C"DIST1))
     (command "leader" pt3 pt4 "" "" "" T1 "")
    )
    ((or(and(> ANG1 "0")(< ANG1 "45"))
        (and(> ANG1 "45")(< ANG1 "135"))
        (and(> ANG1 "135")(< ANG1 "225"))
        (and(> ANG1 "225")(< ANG1 "315"))
        (and(> ANG1 "315")(< ANG1 "360")))    
        (setq H1(getpoint "\nHorizontal Dimension Line Location: ")
              V1(getpoint "\nVertical Dimension Line Location: "))
        (command "layer" "s" DL "" "dim" "horizontal" PT1 PT2 H1 "" "vertical" PT1 PT2 V1 "" nil)
    )         
  )
  (command "layer" "s" CL "")
)

Hi i new to lisp so i don't understand completly what you are trying to do but can't you use the chamfer command that is build into utocad that allows you to chamfer Polylines

Heres a small lisp for using that feature

 

 
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
(defun PLC()

 (setq ply (entsel "\nSelect Polyline you wish to Chamfer: "))
 (setq disa (getreal "\nEnter distance from corner to chamfer: "))
 (setq anga 45)
 (command "chamfer" "angle" disa 315)
 (command "chamfer" "polyline" ply)

);end defun PLC
