PLine lisp command just dont wark

[ersegev]

Hello, 

I'm asking for your help in a very simple but extremely fustrating issue.

I'm using List pline command to draw rectangulars.

Some of them are drawn correctly, but on some the vextex ends uo united. for example with the following command:

(command "PLINE" (list 9.65 10.35) (list 0.65 1.35) (list 1.35 0.65) (list 10.35 9.65) "close" )

I get a strait line instade of a rectangular.

Please help me.

P.S. I use Autocad 2012 for MAc.

ersegev,
perhaps something like

(command ".pline")
(foreach Pt '((9.65 10.35) (0.65 1.35) (1.35 0.65) (10.35 9.65)) (command Pt))
(command "c")

 EDITED

set "OSMODE" to zero and see if it makes difference

hope that helps

Dear Henrique

Eventually it was indeed the OSMODE.

I have no idea whay even when specifically entering vertex coordinates it insists on snaping them to other coordinates.

Any way once I turned OSMODE to 0 it worked great.

Many thanks for your help.

another approach to consider is using entmakex.

(defun LWPoly (lst cls)
  (entmakex
    (append (list (cons 0 "LWPOLYLINE")
		  (cons 100 "AcDbEntity")
		  (cons 100 "AcDbPolyline")
		  (cons 90 (length lst))
		  (cons 70 cls)
	    )
	    (mapcar (function (lambda (p) (cons 10 p))) lst)
    )
  )
)

lst = point list/vertex coordinates

cls= Close/not close

Will work regardless of osmode settings, plus you can supply other properties such as layer, color, lineweight etc....

by adding the properties as an argument 

(defun LWPoly (lst cls lay lw col)

....

)

Once again,

Many manu thanks for the wonderful help.

Your solutions really inspire me.
