Removing small objects in drawing

Feb 19, 2013 5:02 PM

Hello,

 

I have a quastion regarding the removal of small objects in a drawing. I made with ArcGIS a map of the Netherlands. Because it is a detailed map, it also becomes heavy and my computer slows down. I merged some smll elements together with the pathfinder-unite command, but it is still to heavy. So I have to delete some other elements. The problem is that I want to get rid of all the small objects, but I dont know how to select them. Has Anybody an idea, to select objects by seize? It is a topograpic map with for example houses, lamp post et cetera, but I actuallly need only the build areas.

best, Roger

    There is no built-in feature to select objects according to size.

     

    It would be fairly trivial to write a Javascript for it. I once did one to remove path segments having a length below a user-defined threshold. You would need to define "small." Area? Bounds? Length?

    Here's one. Copy and paste into a text editor. Save as plain text with a jsx extension in the Adobe Illustrator CSX/Presets/en_US/Scripts folder and restart AI. Have a document open. It may take some time to run.

    #target illustrator
 
// deletes pathItems smaller than the supplied length
 
var idoc = app.activeDocument;
var howLong = prompt ("Enter the size in points of small paths to be deleted", 2, "Delete Small Paths");
 
for (i=0 ; i< idoc.pathItems.length; i++)
     {
          var ipath = idoc.pathItems[i]
               if ( ipath.width < howLong && ipath.height < howLong)
                    {
                         ipath.selected = true;
                    }
     }
 
app.redraw(); 
 
if(confirm ("Proceed to delete selected items?", "yes", "Confirm Delete"))
     {
          app.cut();
     }
