Markups Core enterEditMode() returning false

function newMarkupGUI(viewer, options) {

  Autodesk.Viewing.Extension.call(this, viewer, options);
  thisViewerId = options.id;
  this.viewer.loadExtension("Autodesk.Viewing.MarkupsCore").then(() => {
    let extension = this.viewer.getExtension("Autodesk.Viewing.MarkupsCore");
    extension.enterEditMode();
    console.log(extension.enterEditMode());
  });
  
}

When I am inside my main js file where I initialize the viewer, I am able to access functions such as enterEditMode() like so:

var extension = viewer.getExtension("Autodesk.Viewing.MarkupsCore");

extension.enterEditMode();

This works. But inside my extension called newMarkupsGUI, it seems getExtension() does not work. I am confused about how this all works, as the documentation is pretty sparse. I would rather keep my extension separate and not hard code the functionality of markups where I am initializing the viewer. Any help would be appreciated, thank you.

Solution

  • I think your problem is related to the viewer reference. You don't need to use this.viewer if you have your viewer as function parameter.

    When using viewer.loadExtension().then() the loaded extension is returned in the promise. You can do something like that :

      viewer.loadExtension("Autodesk.Viewing.MarkupsCore").then((markupExtension) => 
  {
    markupExtension.enterEditMode();
  });
