Inset Faces

Introduction​

The Inset tool creates a new, smaller face inside a selected face, connected by a ring of new geometry. It is the first step in creating windows, panels, or support loops for subdivision surfaces.

Basic Usage​

  1. Select: Select one or more faces.
  2. Activate: Press I.
  3. Adjust: Move the mouse to determine the thickness of the inset border.
  4. Confirm: Left-click to confirm.

Advanced Controls​

While the Inset tool is active (before confirming):

  • Individual (I): Toggles between insetting the entire selection as one group (default) or insetting each face individually.
  • Boundary (B): If you are insetting a face that is on the edge of an open mesh (no neighbor), this toggle determines if the open edge is insets or left alone.
  • Depth (Ctrl): Holding Ctrl while moving the mouse allows you to push the inset face in or out (combining Inset + Extrude).

Common Use Cases​

  • Support Loops: Insetting a face creates a "safety ring" of geometry that prevents textures from stretching and keeps edges sharp when using Subdivision Surface.
  • Windows: Inset a face on a wall, then Extrude (E) it inwards to create a window recess.

Summary​

Inset is essentially "Extrude + Scale" but performed on the same plane.

Key Takeaways:

  • Shortcut: I.
  • Individual: Press I again to inset faces separately.
  • Boundary: Watch out for the B toggle when working near mirror modifiers or open edges.

Documentation for Methodology​

What to document when Insetting

In Your Method Section​

Mention Inset when describing how surface details were created.

In Your Decision Log​

Record the following when using this technique:

  • Purpose (e.g., "Creating support loops for subdivision" or "Defining window frames")
  • Thickness (if precise measurements were used)

Verification​

Check for overlapping vertices if the inset was too large for the face shape. Ensure that "Individual" mode wasn't accidentally left on if you intended a group inset.

Example Methodology Statement​

"To create the control panel details, the top faces were Inset (I) to define the button areas, which were then extruded downwards."
