Corner sharpener 2D & 3D (blender add-on)

This add-on sharpens the corners of 2D and 3D objects under subdivision modifier with just a few clicks.

It appears in the tool section of the 3D view when at least one vertex of an object is selected in edit mode.

Note:

• This add-on saves time by automatically creating supporting edges and removing face edges—tasks that are typically performed manually with the knife tool.
• It works best on convex surfaces.
• The sharpened corners will result in a quad shape.

Usage:

2D Sharpener:

• Switch to Edit Mode and select Vertex Mode.
• Ensure each corner vertex is connected to two boundary edges and one face edge in the mesh.
• Inset the face to create and connect the face edge in the mesh. If it’s already inset, you can skip this step.
• Select the corner vertices you want to sharpen.
• In the Tool section, select "Sharpen It" under the "SharpCorner" Tool.
• Adjust the sharpness by sliding the Factor value.

3D Sharpener:

• Switch to Edit Mode and select Edge Mode.
• Ensure each corner vertex of the edges is connected to two boundary edges and one face edge in the mesh.
• Inset the side face to create the face edge in the mesh. If it’s already inset, you can skip this step.
• Select the corner edges you want to sharpen.
• In the Tool section, select "Sharpen It" under the "SharpCorner" Tool.
• Adjust the sharpness by sliding the Factor value.
