New Object From Selected Geometry is a Blender add-on for creating a new object from geometry selected in Edit mode. You select the geometry you want, and the add-on produces a separate object from it. Because the selection can draw on more than one object, the developer notes it can serve tasks like filling gaps between objects or tracing lines.
The add-on is categorized as a mesh extension and is compact at around 13 KB. It requires no special permissions in Blender and is distributed under the GNU General Public License v3.0 or later. Compatibility is listed for Blender 4.2 LTS and newer, so it targets the current long-term support release and later versions.
Version 1.0.2 improved error handling, refined the options layout, and added new options for creating an object using faces. You can add the extension by dragging and dropping it into Blender or by installing it from disk. The developer's page hosts the download, version history, and issue tracker.
