A device is provided for measuring and marking shapes to be duplicated. Such shapes can include electrical outlets, window cutouts, stair step cutouts and such features on drywall or similar panels. The device has a base, a linear measure rotatably attached to the base about a point of rotation, the linear measure being capable of measuring a distance to corners of an outline of a feature to be copied and capable of rotating from a designated point through at least an angle defined by the outline of the feature to be copied. A distance indicator operatively associated with the linear measure indicates the distance from the point of rotation to each corner of the feature to be copied, and an angle indicator operatively associated with the linear measure indicates each angle to which the linear measure has been rotated when each distance measurement was taken. The device can also include means for recording the linear and angular measurement for each corner of the feature to be copied so that the feature can be duplicated on another object such as a replacement piece of drywall. Both mechanical and electronic embodiments are provided.
