Zapp is a utility add-on that maps a set of common modeling operations to a single hotkey for faster workflows. It includes a tool to instantly generate a single vertex at the 3D cursor location, which is useful for starting point-by-point blockouts.

The toolset also features a specialized smoothing macro that simultaneously applies a level-two subdivision surface modifier, enables smooth shading, centers the object's origin to its mass, and assigns a default metallic gray material. An additional quick-access function is provided for enabling standard auto-smooth shading on selected objects.
