Select Points Along a Y Axis

Hello,

Is there a simple solution via a JavaScript that would allow me to (once I have selected a point) automatically select all of the points that land on that same

Y-Axis?

Possibly even adding points to paths on that same Y-Axis (like in the case of the S in the attached image)?

I am hoping to copy them, move them by .125 below and convert them to rectangles.

I am able to do all of this with an action but the first step.

Any help would be great thank you!

The Script is doing nothing wrong  I'm just ending up with extra line segments.  It's almost like I need it to select all of the points -except- the ones on the Y-axis so I can delete them away.

and end up with this.


So you want something like this ?

#target illustrator 
function test(){ 
    var doc = app.activeDocument; 
    var selectedItem = doc.selection[0]; 
    var selectedPoints = selectedItem.selectedPathPoints; 
    var selectedPoint; 
    var tolerance = 2; 
    for(var i = 0; i < selectedPoints.length; i++){ 
        if(selectedPoints.selected == PathPointSelection.ANCHORPOINT){ 
          selectedPoint =  selectedPoints; 
        } 
    };
    var sampleY = selectedPoint.anchor[1];
    selectedPoint.selected = PathPointSelection.NOSELECTION;
    var thisPath, thisPathPoint; 
    for(var i = 0; i < doc.pathItems.length; i++){ 
        thisPath = doc.pathItems; 
        for(var j = 0; j < thisPath.pathPoints.length; j++){ 
            thisPathPoint = thisPath.pathPoints; 
            if( 
                !(thisPathPoint.anchor[1] - tolerance <= sampleY && thisPathPoint.anchor[1] + tolerance >= sampleY) 
            ){ 
                thisPathPoint.selected = PathPointSelection.ANCHORPOINT; 
            } 
        }; 
    }; 
}; 
test();

Yea you can try this!

Change the tolerance to include more points along a wider buffer area.

#target illustrator
function test(){
    var doc = app.activeDocument;
    var selectedItem = doc.selection[0];
    var selectedPoints = selectedItem.selectedPathPoints;
    var selectedPoint;
    var tolerance = 2;
    for(var i = 0; i < selectedPoints.length; i++){
        if(selectedPoints.selected == PathPointSelection.ANCHORPOINT){
          selectedPoint =  selectedPoints;
        }
    };
    var thisPath, thisPathPoint;
    for(var i = 0; i < doc.pathItems.length; i++){
        thisPath = doc.pathItems;
        for(var j = 0; j < thisPath.pathPoints.length; j++){
            thisPathPoint = thisPath.pathPoints;
            if(
                (thisPathPoint.anchor[1] - tolerance <= selectedPoint.anchor[1] && thisPathPoint.anchor[1] + tolerance >= selectedPoint.anchor[1])
            ){
                thisPathPoint.selected = PathPointSelection.ANCHORPOINT;
            }
        };
    };
};
test();
