Edge loop

[Tovarich]

Buenas gente, viendo un poco esta herramienta, he visto las múltiples opciones, y he visto dos que no sé qué pueden ser, ¿Qué son relative distance from Edge o equal distance from edge?
Las demás opciones más o menos puedo suponer / entender en que consisten. Gracias y un saludo.

Has visto estas explicaciones de Autodesk? Los gráficos son bastante ilustrativos.
Relative distance from edge

When the Maintain position is set to Relative distance from Edge (default) the dotted insert Edge preview locator is positioned along the selected Edge based on a percentage distance along the selected edge. For example, if you click and then drag the selected Edge to a location that is approximately halfway along the selected edge, the dotted preview locator appears approximately halfway betwen all of the other edges along the selected Edge ring.

Equal distance from edge

When Maintain position is set to Equal distance from edge, the dotted insert Edge preview locator is positioned along the selected edges at an absolute distance based on where you click on the first edge. When the Length of edges is highly variable, the tol uses the shortest Edge to determine the maximum distance the preview locator can be moved. This option is useful if you want the new edges inserted at a specific distance from existing edges. For example, when you want to control any subsequent Edge creasing you may perform on the mesh.

Note:
The distance the preview locator can move is limited by the Length of the shortest Edge on the associated Edge ring. If the locator quickly snaps to either Edge it may indicate a shorter Edge in the Edge ring that is limiting the placement.

Bueno había visto ya el manual en la ayuda de Autodesk, pero no me quedaba claro, aún viendo las imágenes, pero he visto un vídeo del canal de Maya Tolbet que me ha quedado bastante claro, para aquellos como yo, con dudas:
Un saludo.
