Blender: Filling Hole in Mesh

 

Filling Hole in Mesh

Blender is useful to fill or mend a hole in a mesh. Holes are typically already present in a mesh or you create them while deleting elements of a mesh.

  • Switch to Edit Mode and then click the Vertex select mode button. You are now ready to select vertices.
  • Select the vertices that border the hole. To do this, keep the Shift key pressed down while you select the vertices by using the mouse button
  • Press the f key to fill the hole. Blender tries to fill the hole with a suitable polygon. If you want to fill with triangles, then repeat these steps for every 3 vertices that form those triangles.
