Could someone please explain which method is better for chaning the rotation angle.

That is kind of like asking, "which is better, Ford or Chevrolet?"

Let the debate begin....

i use a modified lisp that can do both, depending on what is the best option at the moment (again,
thanks to the original author, whoever you were):


(defun c:dvsnap ( / oldcm twang newang pmpt)
(setq oldcmd (getvar "cmdecho"))
(setvar "cmdecho" 0)
(initget 0 "New 0") ;Set up the user to win
(setq pmpt (getangle "\nType in new Rotation Angle or Pick 2 points: "))
(if (= pmpt nil)
(setq pmpt "0")
)
; (setq TWANG (GETVAR "viewtwist")) ;get the current dview twist in radians
(setq TWANG (/ (* pmpt 180.0) PI)) ;so lets get it to degrees
; (setq TWANG (/ (* pmpt PI) 180)) ;so lets get it to radians
(setq TWANG (* twang -1))

; (if (= pmpt "0")
; (progn
; (if (= 0 twang)
; (setvar "snapang" 0)
(progn
(command "dview" "" "tw" twang "")
(command "snap" "off")
)

;set the snap angle to the negative of the twist angle
(setq SNAPANG (* TWANG -1))

;Rotate the snap
(command "snap" "r" "" SNAPANG)
(command "snap" "off")

(if (= pmpt "New")
(progn
(command "snap" "r" "0,0" "perp" pause)
(command "snap" "off")
)
)
(setvar "cmdecho" oldcmd)
(princ)
);end dvsnap defun
;;---------------
(defun C:UCSV (/)
(command "ucs" "v")
(command "snapang" "0")
(princ)
);end ucsv defun
;;---------------
(princ "\n \"DVsnap\" loaded.\n Type DVSNAP to orient view and x-hairs, type UCSV to orient UCS to
View")
(princ)

Do you have people who will try to use ldd commands when the drawing has a ucs other than world? Then come bug you about why things dont work? Do you have to fix the problems people create when they change the ucs then do a profile?
After you start spending most of your time on trouble shooting other peoples (self created) problems you will probably try to get people to stick with dview.

Use them both as Bill said. They are both very useful and powerful tools.

My take on the UCS "problems"
The worst thing that ever happened here was someone imported points with a
UCS set. He set the dwg to World coords, removed the points & reimported in
less than 3 min. Another common "problem" is someone may draw a 3d pline &
they won't see it. They either move & rotate it to the proper location or
redraw it. We have never lost data or a great deal of time from these minor
UCS blunders.

If you like to use UCS's there is nothing wrong with it just keep the
Ucsicon visible at all times so the confusion is avoidable and keep the
staff up to speed.
