CURVE LABEL

Hello everyone, I need some help with this lisp. What this lisp does is it prompts you to select an arc... then using an existing block with the arc number, delta, length, tangent, and radius labels as an attribute...it fills in the label of the attribute. The problem that I am having is that it's not placing the info in its proper label slot. It puts the tangent info in the length label and the radius in the arc number label...etc.

I have been trying to solve this issue, but no luck. Can anyone help?

forgot to mention........i use acad2004

 

Hi,

When you populate the attribute fields in a block, they are populated in the
order the attributes were selected when making the block definition.

Hence you need to redefine the block to match you lisp code, or re-order the
lisp code to match the block definition.

Simply experiment with the parameter order in the line:

LNGTH TANGNT)

prompts you to select an arc... then using an existing block with the arc
number, delta, length, tangent, and radius labels as an attribute...it fills
in the label of the attribute. The problem that I am having is that it's not
placing the info in its proper label slot. It puts the tangent info in the
length label and the radius in the arc number label...etc.

 

Okay..got it to work thanks a lot. One more question. i am trying to run another lisp .... I wrote in as such:

(setq lst2 (sort lst2))

It should run "lst2" thru a little lisp to obtain a new "lst2" value.
For some reason it is not working correctly. Is the codeing bad?

Example: if lst2 = 1 2 3 4
lst2 goes to the lisp labeled "sort" and should returm 4 3 2 1

here is the sort lisp...

( defun SORT (Lst / NewList temp big TempList y x limit)
( setq x (length Lst) )
( while ( /= x 1)
( setq pos 0 )
( setq big (nth pos Lst) )
( setq i 1 )
( setq limit (- x 1 ) )
( repeat limit
( setq temp (nth i Lst) )
( if (> (atoi (car temp)) (atoi (car big)) )
( setq big temp pos i )
)
( setq i (+ i 1) )
)

( setq NewList ( cons big NewList ) )
( if ( = pos 0 )
( setq Lst (cdr Lst) )
( progn
( setq TempList (list (car Lst)) )
( setq y (length Lst))
( setq y (- y 1) i 0 )
( while (< i y )
( setq i (+ 1 i) )
( if ( /= pos i )
( setq TempList (cons (nth i Lst) TempList))
)
)
( setq Lst TempList )
)
)
( setq x (- x 1) )
)
(setq NewList ( cons (car Lst) NewList ) )
(setq Lst NewList )
)

 

I think you can call it a lisp with-in a lisp..... yeah , that's what it is...
