Import point + text on different layer lisp

Hy,

im a rookie with lisp, so i need an help (a big one) to complete a lisp.

I have an external txt file with a lot lines. The columns are in this way:

1st COLUMN: PROGRESSIVE NUMBER
2nd COLUMN:	x COORDINATE
3rd COLUMN: 	y COORDINATE	
4th COLUMN: 	z COORDINATE		
5th COLUMN:  DESCRIPTION

and i need to create in autocad a point with the coordinate and three texts at his side: the point and the texts must be on different layers and i need a separate block for every point with its texts (a block for every line of the external file).

my idea was something like this:

IMPORT POINT + TEXT LISP
1-	IF THE LAYER DOESN’T EXIST: CREATE LAYER “LEV BLOCK” (INDEX COLOR YELLOW: 2)
2-	IF THE LAYER DOESN’T EXIST: CREATE LAYER “LEV POINT” (INDEX COLOR YELLOW: 2)
3-	IF THE LAYER DOESN’T EXIST: CREATE LAYER “LEV TEXT NUMBER” (INDEX COLOR YELLOW: 2)
4-	IF THE LAYER DOESN’T EXIST: CREATE LAYER “LEV TEXT Z” (INDEX COLOR GREEN: 3)
5-	IF THE LAYER DOESN’T EXIST: CREATE LAYER “LEV TEXT ANNOTATION” (INDEX COLOR RED: 1)

6-	COMMAND “PDMODE” “32”
7-	SETQ “HEIGHTofTEXT”
8-	HIDE OBJECTS: ALL

9-	CURRENT LAYER: LAYER “LEV POINT” 
10-	CREATE POINT (IMPORT FROM EXTERNAL FILE THE COORDINATE (1st LINE: 2nd COLUMN 3rd COLUMN, 4th COLUMN)
11-	CURRENT LAYER: LAYER  “LEV TEXT NUMBER”
12-	CREATE MTEXT (IMPORT FROM EXTERNAL FILE THE COORDINATE (1st LINE: 2nd COLUMN+“HEIGHTofTEXT”*1.5,  3rd COLUMN+“HEIGHTofTEXT”*1.5, 4th COLUMN)(TEXT HEIGHT “HEIGHTofTEXT”)(TEXT: NUMBER IN THE 1st COLUMN)
13-	CURRENT LAYER: LAYER  “LEV TEXT Z”
14-	CREATE MTEXT (IMPORT FROM EXTERNAL FILE THE COORDINATE (1st LINE: 2nd COLUMN+“HEIGHTofTEXT”*1.5,  3rd COLUMN, 4th COLUMN)(TEXT HEIGHT “HEIGHTofTEXT”)(TEXT: NUMBER IN THE 4th COLUMN)
15-	CURRENT LAYER: LAYER  “LEV TEXT ANNOTATION”
16-	CREATE MTEXT (IMPORT FROM EXTERNAL FILE THE COORDINATE (1st LINE: 2nd COLUMN+“HEIGHTofTEXT”*1.5,  3rd COLUMN-“HEIGHTofTEXT”*1.5, 4th COLUMN)(TEXT HEIGHT “HEIGHTofTEXT”)(TEXT: TEXT IN THE 5th COLUMN)

17-	CURRENT LAYER: LAYER “LEV BLOCK” 
18-	SELECT: ALL
19-	CREATE BLOCK
20-	HIDE OBJECTS: ALL

21-	REPEAT FROM 9 TO 20 FOR ALL THE LINES IN THE EXTERNAL FILE

22-	UNHIDE OBJECTS

I started to write the lisp and i arrive at the point 9 in this way:

(defun C:LEV ()
 
 (command "_.layer" "_MAKE" "LEV BLOCK" "COLOR" "2" ""
  "_MAKE" "LEV POINT" "COLOR" "2" ""
  "_MAKE" "LEV TEXT NUMBER" "COLOR" "2" ""
  "_MAKE" "LEV TEXT Z" "COLOR" "3" ""
  "_MAKE" "LEV TEXT ANNOTATION" "COLOR" "1" "" "")
   
  (COMMAND "PDMODE" "32" "")
  (COMMAND "HIDEOBJECTS" "ALL" "")
  (COMMAND "_.CLAYER" "LEV POINT" "")

(PRINC)  
)

From here i dont know how to import the coordinate to create the points, the coordinate to create the text (my idea is to use the coordinate of the point and move a little bit the text on the right using the height of the text X a number)

Somebody can help me? I will appreciate a lot.

A good ideas is write a little defun that checks for the layer and add that to an autoloading lisp like acaddoc.lsp this way its available for any program you write. Items 1-5

(laynew "lev_block" 2 "Continuous")

lee-mac has a good read line lisp that can make a list using a delimeter normally it would use the "," or a CSV file but you can use a space etc. If your columns are fixed length always then you can use substr start end to read the number of characters.

If you post a sample file it will confirm what your data file looks like, what you are asking for has been done many times only variation is the different layers.

Check out http://www.Lee-mac.com point manager.

Another you can set variables directly like current layer (setvar 'clayer "TEXT") pdmode osmode filletrad to mention a few without using Command.

Here is a simple make layer save it to say a autoloading lisp like acaddoc.lsp

(defun mynewlayer ( layname col lt / )
(if (or (= lt "C")(= lt "c"))(setq lt "Continuos")) ; shorthand typing in calling code
(if (= (tblsearch "layer" layname) nil)
(command "_.layer" "_MAKE" layname "COLOR" col "" "LT" lt "" "")
)
)
; in program
; (mynewlayer "BIGAL" 3 "c")
