The above one is Inset by Safe Inset
The below one is Inset by Blender’s built-in Inset tool.

Unlike Blender’s built-in inset, Safe Inset can detect and avoid overlapping.

It works for very complex n-gon face.

This tool is useful for general modeling and many use case. It works great for Sci-Fi shape and hard surface modeling.

Usage

Switch to Edit mode, Face mode

Select a face, then right click in the 3D viewport,

Select Safe Inset at the bottom of the blender’s context-menu.

Options :

Inset Size : the amount to inset

Threshold : this is the minimum size to determine “overlapping”.

Merge Result : when this option is enabled, it will merge the result vertices that are very close.

Merge Distance : the distance for merging

Update

Version 2.0.1, 2.0.2, 2.0.3, 2.0.4

Fixed a bug for calculation

Version 2.0.0

Using a new algorithm and largely improved the robustness !

Now it works for very complicated face and no overlapping.

Version 1.2.2

Now the Inset face in the result will be selected

Version 1.2.1

Fixed a small bug for speed and smoothness

Version 1.2.0

Largely improved the algorithm. Now produce better result (correct edge offset) and more stable.

Version 1.0.1

Fixed a bug when all vertices become one point.
