Hello

I am going to create the scripts which draw closed plines (the project of photomask). Finale scripts should draw several plines composed of up to several hundreds segments each. However my simple test script is not able to draw correctly two sets, each composed of two triangles one vertex touched, which are encompassed by a polygon.

If I copy each line from script independently to the command line of AutoCad, the plines are drawn correctly. When I execute the script the plines are drawn incorrectly but what is strange to me: looking into the history of the AutoCad command line I found that commands from script are read in proper order and are correct (as in case when one does ctrl-c, ctrl-v from script file ).

I am sure that at the end of each line of script file there are no hidden characters - each line ends with CRLF as should in windows text files. I only found in AutoCad help that varbiale BACKGROUNDPLOT should be set to 0. I checked the operation of the script on AutoCad 2007 and 2008 installed on two different computers. I tested script with and without commentary lines. Please find the script code below (unit: micron):

I didn't understand how the script process failed. Was anything drawn? Any clues on the command line?

If vertexes are drawn at wrong location, maybe you need to turn off running object snap (set osmode to 0) before running the script.

Hello

Finally I have found the error in my script. Each command must be started and closed in a single line of the script; a line is ended with CR LF in Windows OS. I thought that "command" means the name of a given command (ex. _pline), however the command means command including variables. Here is the correct from of the script:

;obiekt num.1 sekcja num.1, znaczniki
_pline 53700.0,62350.0 53700.0,62450.0 53800.0,62400.0 close
_pline 53800.0,62400.0 53900.0,62450.0 53900.0,62350.0 close
;obiekt num.1 sekcja num.1, znaczniki ramek
_pline 53680.0,62320.0 53680.0,62480.0 53800.0,62420.0 53920.0,62480.0 53920.0,62320.0 53800.0,62380.0 close
;obiekt num.1 sekcja num.1, znaczniki
_pline 53700.0,62550.0 53700.0,62650.0 53800.0,62600.0 close
_pline 53800.0,62600.0 53900.0,62650.0 53900.0,62550.0 close
;obiekt num.1 sekcja num.1, znaczniki ramek
pline 53680.0,62520.0 53680.0,62680.0 53800.0,62620.0 53920.0,62680.0 53920.0,62520.0 53800.0,62580.0 close

The last line should be ended with a single blank space not with CR LF.

Best Regards

Glad to hear you sorted it...but...
To not leave wrong information for others, there was nothing wrong with your original script format. You can use a space or a line feed (enter) in a script to achieve an "enter" in autocad. it sounded like the problem you had was lines drawin in error, that wouldn't be caused by script format.

In other words, these scripts are equivalent:

_pline 53700.0,62350.0 53700.0,62450.0 53800.0,62400.0 close

and

_pline
53700.0,62350.0
53700.0,62450.0
53800.0,62400.0
close
