Polygon modeling requires a lot of work to increase vertices (points) and sides (edges) using loop cuts and knife tools on objects such as cubes that are the base. It may be necessary to perform detailed work such as filling in the surface.
In this article, I will introduce the details and how to use the three tools that can be used in Blender.
Most Powerful Tool in Blender :
Blender has several tools that can facilitate such work. Commonly used tools include Bridge Edge Loops, Auto Merge, and Fill. It will be one of your best tools.
Bridge Edge Loops
In edit mode, select the edge you want to fill as a face using the Shift key, etc., and select " Edge loop bridge " from " Edge " at the top of the viewport to create a new face via the selected edge.
In addition, applying an edge loop bridge with adjacent faces selected will remove the overlapping faces and merge the objects.
Auto Merge tool in blender
This fill can also be applied from the " Face " and " Fill " items in the top menu, but depending on the mesh, the result may be different from when using the shortcut key.
I think it's good to use the shortcut key to fill the hole in the polygon and then use the knife tool to adjust the geometry.
