How to call for graphic line length using extendscript?

Graphic lines don't have a length property, but they do have a strokeWeight property. Rob's approach -- to use the geometricBounds of a line to set its dimensions -- works perfectly fine, but for completeness' sake here is how you'd add a line and use its weight property:

line = app.activeDocument.graphicLines.add (myLayer, {strokeWeight: 2});
line.paths[0].entirePath = [[10,15],[35,15]];

So you create a line, then say that its path is between two points.

Hi @Ben-ind , there’s no width or length property, so you’ll have to set the bounds. Here’s the API property listing:

https://www.indesignjs.de/extendscriptAPI/indesign-latest/#GraphicLine.html

You could write and call helper functions to make it easier. Something like this where my setLineWidth function defines the x,y start and the width for the line—25pts in this case:

Edited code:

app.scriptPreferences.measurementUnit = MeasurementUnits.POINTS;
myLayer = app.activeDocument.layers.add({name:"Line"})
app.activeDocument.graphicLines.add(myLayer, undefined, undefined, {geometricBounds: setLineWidth(10,15,25), strokeColor:"Black"})





/**
* Returns geometric bounds for a defined width 
* @ param x the line’s x start
* @ param y the line’s y start
* @ param w the line’s width
* @ return geometric bounds array 
* 
*/
function setLineWidth(x,y,w){
    return [y,x,y,x+w]
}
