Get length of MLeader/QLeader spline.

[BIGAL]

New answer, when you draw a pline did you know you can pick start point, drag mouse for next point, BUT type in length no need for "L". Tested seems to work ok in original code.

 

Starting point of Mleader Enter to stop : 
: _pline
Select start of polyline or [Follow] <Last point>: 
Set next point or [draw Arcs/Distance/Follow/Halfwidth/Width]: 50
Set next point or [draw Arcs/Distance/Follow/Halfwidth/Width/Undo]: 75
Set next point or [draw Arcs/Close/Distance/Follow/Halfwidth/Width/Undo]: 100
Set next point or [draw Arcs/Close/Distance/Follow/Halfwidth/Width/Undo]: 
Existing length is 225 Enter new length 220
Enter label AAA

 

Ok fixed the defun code, its messages may have been misleading.

(defun plpts ( / pt)
(command "_pline" (getpoint "\nStarting point of Mleader : "))
(while (= (getvar "cmdactive") 1 )
(command (getpoint (getvar 'lastpoint)))
)
)
