Tube2curve is an add-on that automates the process of converting tubular geometry back into editable curves. It generates a perfectly centered curve or edge down the middle of selected tube meshes, which is particularly useful when working with baked assets or imports from other applications. The tool handles multiple topologies, including open tubes and those with Ngon or triangle caps.

The add-on requires tubes to have distinct start and end points; continuous cyclic geometry must be manually split before conversion. Additionally, the package includes a utility operation to separate curve objects by loose parts.
