This app is great for exporting labels to another drawing and reimporting for referencing a different surface.
The app provides the ability to export surface labels (contour labels, slope labels, and spot elevation labels) to a text file.
The app saves the label's type and associated settings, current style names, and positional coordinates including drag positions.
The app also allows for importing from the text file and recreating the labels in the positions/styles and referencing a different surface.
