An Outline is selectable on a Photo, a 3D Viewer or the Outline Table, by clicking on it in Select mode. If the Outline has a ‘part’ to it, e.g., a Fillet or if the Outline was formed by connecting multiple Outlines, then the various parts can be selected by clicking again on the Outline but in the region of the part. The Outline is selected first, then the part is selected on the second click. While in Select mode, there is also a right click menu item to select the Outline Part.
