Transform Panel

Mode:Edit Mode
Panel:Sidebar ‣ Transform

When nothing is selected, the panel is empty. When more than one control point is selected, the median values are edited and "Median" is added in front of the labels.

Control Point, Median
The first controls (X, Y, Z) show the coordinates of the selected point or handle (vertex). The last control (W), defines the weight of the selected control point or the median weight.
Space

The Space radio buttons let you choose if those coordinates are relative to the object origin (local) or the global origin (global).

Global, Local

Weight
Controls the "goal weight" of selected control points, which is used when a surface has Soft Body physics, forcing the surface to "stick" to their original positions, based on the weight.
Radius
Surface objects do not have a Radius property, this value has no effect.
Tilt
Surface objects do not have a Radius property, this value has no effect.
