The draft angle inspection tool is a great way to visually confirm that a part is ready to be cut for use as a mold or tool. However, when a part contains negative draft, and is not suitable for use as a mold or tool, it can be difficult to remove these negative draft areas, especially if the model is imported. It would be quite convenient if there was an option to add material in these areas of negative draft by basically filling in the area created by the nearest zero-draft edges.
For example, it would be convenient to quickly fill all yellow and red areas in the image above. I understand the inspect draft angle tool likely uses visual shaders to accomplish something like the image above, and so this functionality would likely be difficult to implement, but I hope it is at least worth consideration.
