View direction of vectors
Hi,
Is it possible to see in what direction a vector goes?
For instance, if I draw a polyline based shape in a counter clockwise direction, I obviously know the direction. But if I draw a shape which is built up out of different shapes, exploded, trimmed, and joined again, I have no idea of the direction of the vectors. For cnc tool radius correction, it's important to know in what direction it goes.

You can use a linetype with arrows.
*ARROWS,Arrows > > > A,1,[ZIG,ltypeshp.shx,r=90,x=0.25,y=0.25,s=0.25],1

Also when changing Length in Properties  which end will change?

There are a few is anticlockwise lisps for plines then can do Pedit R.
;; get closed polygon's area
(defun sspts2area (l)
(/ (apply (function +)
(mapcar (function (lambda (x y)
( (* (car x) (cadr y)) (* (car y) (cadr x)))))
(cons (last l) l)
l))
2.)
);_force pointset CCW
(setq plent (entsel "\nPick pline"))
(setq coord (mapcar 'cdr (vlremoveifnot '(lambda (x) (= (car x) 10)) (entget (car plent)))))(if (< (sspts2area coord) 0)
(command "pedit" plent "R" "")
)
Howdy, Stranger!
