Cannot import files to Digitized Shape to Surface

Hi,

I am going through the training of Digitized Shape Preparation. And in the Exercise: Align and Analyze a Digitized Part, I have problem on importing the .3dxml file into the Digitized Shape to Surface app. When I import the file, it opens a new tap instead of creating the object into the Digitized Shape to Surface app. It would be great if I can get some help on this. Thanks
