[vivekgrs]

hi everybody,

i want 2 capture the attribute values of the point and display it in the drawing by using autolisp.

by using entget we can get the information about the entity, by using which command we can able 2 retrieve the attribute data.

 

in the entmake command,

entmake '(( 0 . "text")(40 . 0.2)(nth count plist)(1 . "missing") ---- by giving like this means its working fine. but in this i want 2 use variable which has capture the data while running.

for ex

(setq trs(cdr(assoc -1 ent) ----- entity name

now i want 2 use the variable in entmake.

i had used as

(entmake '((0 . "text")(40 . 0.2)(nth coutn plist)(1. trs) ------ its showing error. bad dxf code.

can anyone gave me help to solve the problem.

I abswered your question at the 'other' forum also...

 

You are using the variable 'trs' to supply a string value and combine it into a data pair. You *can*use only literal values in a quoted list, as variables will not be evaluated. When including variables in a list, use the "list" function rather than a quote (apostrophe). Also, to create a "dotted pair" list (two values separated by a period), use the "cons" function.

 

So you should use;

 

(entmake 
  (list
     (0 . "text")
     (40 . 0.2)
     (nth count plist);;<<-??Is this a data pair?
     (cons 1 trs))
  )
)

How can I convert 3d to 2d, I mean z=0

you can convert a point like this:

((lambda (x) (list (car x) (cadr x))) (getpoint))

or just

(setq point1 (getpoint)
       point1z (list (car point1) (cadr point1))
)
