Multi Adjust gathers common Blender tweaks into one panel so several objects, mesh elements, or curve points can be adjusted together. With a single click you can match location, rotation, scale, or origin across every selected object, and switch between local and world space when aligning objects or mesh points. It can flatten or align mesh selections and curve handles by typing the X, Y, or Z value you want, tweak curve weight, radius, or tilt while adjusting position, and flip viewport or render visibility for the whole selection in one pass.
To use the panel, select your items, open the Multi Adjust tab in the 3D Viewport sidebar, enable the axes you care about, type the numbers, and press the apply button for your current mode. A command box also accepts short typed lines such as rx=45 or x=0 z=2; Multi Adjust reads the words, updates the panel, and runs the matching action.
