MagicaCSG Feature: Groove Blend (Patreon)

The new Groove blend mode allows you to apply Boolean operations within a certain thickness around the surface (i.e., you can use primitives to extrude the surface).

In the first image, left is without groove blend, right is with groove blend.

You can also add blend factor or fillet/chamfer blend to this mode.

If you only want to apply this on the intersected edges, you can add hole/shell to the primitive.
