Mesh Stuff is an addon for Blender aimed at making modeling in edit mode easier. It adds four functions to the edit-mode toolset, along with guide lines introduced in a later update. The addon is only visible and only works in edit mode, appearing in the side panel under a Mesh Stuff tab.
Distribute places two selected mesh objects evenly on a straight line, with the amount set afterward. Rotate builds a circular array around a face or edge chosen as the rotation center. Plane to Plane orients mesh objects by their faces, placing the first plane on top of another along with its linked geometry, and the orientation can be adjusted. Mirror reflects a mesh across a chosen plane, vertex, or edge, including geometry that isn't connected.
Installation uses Blender's preferences menu: download the addon zip and select install. Version 0.0.4 was tested with Blender 4.4, and the addon is distributed under the GPL license. A demo video is available.
