Using Express Commands In repeat

[MiGo]

I have written a script that performs many actions. I have an if statement that runs to end the script uppon reatching the number of viewports in the layout tab, but what i'm after is just repeating the commands x number of times where x would be the number of viewports in the drawing. This would allow my routine to have no maximum number of viewports.

 

In the script I currently use the express tools extrim and burst. I downloaded a cookiecutter lisp that deletes everything outside my viewport border that is drawn by another lisp i have downloaded called vp-outline. If i don't have to select anything or pick points I can just run the lisps with a line like (c:vp-outline) but when running the express tools they I haven't been able to tell it what it wants inside the repeat. Any ideas?

Hmm, not sure what your question is...

Is this a script (.scr) or a lisp routine?

If you just wnat to know how to repeat a number equal to the number of Layouts, that would be:

 

(repeat (length (layoutlist))

 

If you need to supply responses to an Express Tools command, most likely you can't do that in a lisp but you could in a script. Will need more info.

I am working with a .scr file. I run this script on a batch of drawings through a program called script pro. This program allows you to run a script on a drawing set and will time out and move to the next drawing if there are errors to ensure the entire set is completed.

 

I have the repeat logic already done, but what I need answered is how to use an express tool like extrim or burst inside the repeat

 

(repeat (1- (length (vports)))

(c:vp-outline) ;;works great because needs no input

(c:extrim) ;; wants input after repeat runs??

(more stuff here)

)

 

I need to know how to tell extrim to use the vp-outline line that was drawn and how to tell it a point. The vp-outline generates a polyline of the current viewport, so it satisfies the "last" entry. Also I can put it into a group and extrim allows you to select a group.

I see, you are running a script but the call to Express Tools is from lisp code. I don't believe there is a way to supply arguments to the (c:extrim) function from a lisp. Many have tried.

 

Here's a thought, create a script to run extrim.

So in the lisp, instead of

(c:extrim)

 

use

(command "script" "trimit.scr")

 

and "trimit.scr" would consist of

 

EXTRIM
L
0,0

 

or instead of a hard coordinate, maybe a lisp variable named "VP_Cen" supplied in the script with

!VP_Cen

I have found a solution. I have created if statements inside the script that run certain sections if a counter indicates it han't been run yet, and if that counter hasn't reached the number of viewports in the drawing I run the script again via rscript.
