thicken/inflate edges verts and faces

basically when you try to thicken/inflate certain edges or faces using solidify modifier using vertex groups well the result is terrible normals are corrupted with topology too i advise this tool basically it will make a plane 3d but according geometry so no messed up topology and geometry that isnt connected to the main mesh basically this will be helpful when you by mistake make a tail flat and using mirror clipping you can just thicken the flat tail using this tool instead of the messing process of reconstructing it because solidify modifier will only add fuel to the fire and make the mess worse
