override angle in lisp?

[mojo8997]

got another question, i want to draw pline from 0,0,0 but override the angles as i go, any tips? this is what i was trying an it dosent work, trying to make a box to start off

 

 
(defun c:cline ()
 (command "PLINE" "0,0,0" "<0" "1" "<90" "1" "<180" "1" "c")
 )

 

I just tried

 

 
(vl-load-com)
(defun c:cline ()
 (vl-cmdf "PLINE" "0,0,0" "1<0" "1<90" "1<180" "c")
 )

 

still no luck

I at first would calculate vertex in the Lisp

(setq t1 '(0 0)
     t2 (polar t1 0 1)
     t3 (polar t2 (/ pi 2) 1)
     t4 (polar t3 pi 1)
)

Then

(vl-cmdf "_pline" "_non" t1 "_non" t2 "_non" t3	"_non" t4 "_c");_non - there is no snap

And with a tracing angle, likely it not to turn out, after all tracing on an angle works in two parties and how it without the user will choose one?
