A measuring assembly for measuring the contour of a workpiece has a measuring probe that is pivotably supported and deflectable about a first axis (measuring axis) in order to contact a surface of the workpiece, and has a second axis that is associated with the workpiece. The first axis and the second axis are parallel or approximately parallel to one another for radially contacting a surface of the workpiece. A device for rotating the measuring probe and the workpiece relative to one another is provided, such that the measuring probe contacts the surface of the workpiece during the rotation, and a device for plotting the angular deflection of the measuring probe as a function of the particular rotational position of the workpiece relative to the measuring probe is provided.
