Problem accessing unitsManager

[billoverman]

I have a very short script program (js) that won't run or debug.

I've narrowed it down to a call to design.unitsManager. If I comment out the line below where I'm trying to get the unitsManager, everything works fine. I can even evaluate in the console and see that design.unitsManager is indeed a fusionUnitsManager.

However, if the line is as shown (i.e., not commented out) Chrome doesn't launch at all. In Fusion I see the spinning dots in the list of Scripts next to my script name (and the Stop button is enabled).

This seems to follow the example program for UnitsManager.

Any ideas?

    }
 
    var ui;
    try {
        var app = adsk.core.Application.get();
        ui = app.userInterface;
 
        var doc = app.activeDocument;
        var product = app.activeProduct;
        var design = adsk.fusion.Design(product);
        var rootComp = design.rootComponent;
        var eval = design.unitsManager;  // ============ this is the line that doesn't work

    } 
    catch (e) {
        if (ui) {
            ui.messageBox('Failed : ' + (e.description ? e.description : e));
        }
    }

    adsk.terminate(); 
}

The problem is caused by the variable name "eval" which is the built-in function of JavaScript. Changing the name will solve the problem.

Hi,

You need to change the variable name "eval" to another one. Because eval is a function of JavaScript. The code below should work.

var eva = design.unitsManager;

I thought of that and tried a bogus variable name. I also tried inlining the
expression everywhere I used it. No change in behavior.

You mean by changing the variable name, the issue still exists? I tried to run it locally, but it works fine. Can you try the following code again? If the problem still exists, please zip your script(include html, js, manifest) and post it as attachment, so we can investigate if there is any other issue.

function run(context) {

    "use strict";
    if (adsk.debug === true) {
        /*jslint debug: true*/
        debugger;
        /*jslint debug: false*/
    }
 
    var ui;
    try {
        var app = adsk.core.Application.get();
        ui = app.userInterface;
 
        var doc = app.activeDocument;
        var product = app.activeProduct;
        var design = adsk.fusion.Design(product);
        var rootComp = design.rootComponent;
        var eval_ = design.unitsManager;  // ============ this is the line that doesn't work

    } 
    catch (e) {
        if (ui) {
            ui.messageBox('Failed : ' + (e.description ? e.description : e));
        }
    }

    adsk.terminate(); 
}

 Another thing is if the script is still running , please stop it, before debuging or running.

Thanks. That worked.

I thought I had done exactly what you suggested, but apparently not.
