Syntax for script file to insert blocks with attributes
Posted: Jan 8, 2009 5:12 PM

survey point block.PNG (6.6 KB)

I'm having difficulty in getting the right syntax in a script file for inserting survey point blocks with attributes. The block is simply a node with 3 attributes for point number, elevation and description.

Below sample line from the script doesn't work properly:

-insert spnt 5608116.302,371366.6888 1 1 0 P1 14.6014 TOE

Below sample lines do work properly (read further below):

-insert spnt 5608116.302,371366.6888 1 1 0 P1

14.6014

TOE

spnt is the point block

P1 is the point number attribute

14.6014 is the elevation attribute

TOE is the description attribute

System variable ATTREQ = 1

ATTDIA=0

The block is inserted in the drawing ok except the point number, elevation and description is read as the first attribute value. The remaining attributes take on their default value. See attached sample of point block.

I can get it to work properly if I place the elevation and description attribute on a separte line. The problem is that I have hundreds of points that are taken from an excel spreadsheet and saved into a notepad script file as ascii text. I would have to edit each point in the script to place the elevation and description on a separate line which is too time consuming and somewhat defeats the purpose of using a script.

Is their some way of possibly placing a carriage return control character between the point number, elevation and description to fool autocad in thinking that they are on a separate line in the script file?

Any help or suggestion would be much appreciated.

It would be a good idea to use semicolons instead of spaces for the
"enter" keys 0 then you can sure that you have exactly the correct
number. Your macro looks OK in principle but when you run it you need
to look at the command line and see what/where the error is. You can
cust and paste form the AutoCAD text screen to a message here. If the
attribures hace spaces you need to put them in quotes e.g. "test 1".

Thanks for your reply. Since I posted the first message I found another way to get all of the attributes on the same line. I wrote a one line autolisp expression instead. I seems to work just fine.

Thanks again

Can you please explain to me how a semicolon is used in a script to behave like hitting the return key? This does not work for me. As far as I know semicolons are used for commenting text in a script file.

Semicolons ARE the same as Enter key in a script file - as well as a
space. Use of them is other type files are for commenting.

I won't believe it unless I see it. Can you please show me an example.

Thanks.

Here's one - note last line with spaces are same as pressing the Enter key.
; ARCLEADR.LSP
; DRAWS ARC WITH STANDARD ARROW HEAD
(defun c:arcleadr (/ startpnt anglepnt endpnt1 endpnt2)
(graphscr)
(command "cmdecho" 0)
(initget 15)
(setq startpnt (getpoint
"\nStarting point for arrow: "))
(setq anglepnt
(getpoint startpnt
"\nSelect angle definition point: ")
)
(setq endpnt1
(polar
startpnt
(angle startpnt anglepnt)
(* 0.1875 (getvar "ltscale"))
)
)
(setq endpnt2 (* 0.0625 (getvar "ltscale")))
(command "pline" startpnt "w" "0.0" endpnt2 endpnt1
"w" "0.0" "0.0" "arc"
)
(princ))
(command "-layer" "s" "0" "")

That looks like a lisp file not a script file.

Thanks for your response.

I don't see your point about the spaces you mentioned on the last line. This is an autolisp statement and there are no spaces.

I guess I'm not making myself clear enough. I didn't want an autolisp but rather a true script similar to how you would input on the command line or like a menu macro. I hope this is clear.

Thanks again.

Cheers
