There is provided an apparatus configured to be used with a processing unit for determining a dimension of a selected surface of an object, the apparatus comprising i) a piece of stretchable fabric having a shape adapted to fit the selected surface of the object such that the piece of fabric stretches proportionally to the dimension of the surface when draped thereover; ii) a plurality of uniquely identified beacon devices disposed on the piece of fabric when unstretched in accordance with a first spatial configuration known a priori, where, when the piece of fabric is draped over and stretched by the surface, the beacon devices automatically shift position and form a second spatial configuration as a function of the dimension of the surface; and ii) electronic means for detecting the second spatial configuration and for generating data representing the second spatial configuration; where the processing unit is configured to receive data associated with the first and second spatial configurations and to determine the dimension of the surface as a function thereof. |
