Tools on the Polygon tab let you modify polygons in the scene view.

Shelf items

Removes geometry on one side of a plane.
Deletes points, primitives, and edges from the input geometry and repairs any holes left behind.
Collapses edges and faces to their centerpoints.
Sharpens edges by making their points unique and recomputing the point normals.
Inserts more points the edges of polygons.
Flips the direction of polygon edges.
Controls the smoothness of faceting of a surface.
Merges points together.
Bevels points and edges of polygonal geometry to create a smoother look.
Fills in polygons between boundary edges.
Allows you to extrude and scale, rotate, translate, and/or inset polygonal faces and edges.
Creates new polygons to join existing polygons.
Reduces the number of polygons in a model while attempting to preserve its shape as much as possible.
Divides existing polygons into new multiple polygons.
Smooths out polygons, meshes, and curves without increasing the number of points.
Subdivides polygons into smoother, higher-resolution polygons.
