A device and method for designing an ophthalmic lens includes a design of shape according to a Zernike polynomial, and calculating a curvature of each point of the target surface shape to obtain a curvature distribution overall. A diopter distribution over the target surface shape corresponding to the obtained curvature distribution is calculated, and the calculated diopter distribution is matched against a preset diopter distribution. If matching, a processing machine is controlled to manufacture the ophthalmic lens according to the Zernike polynomial. If not matching, the Zernike polynomial is modified, until the actual surface shape as measured is sufficiently close to the target surface shape.

Systems and methods for manufacturing light fixtures. A data processing system can identify a plurality of attributes of a lighting system. The plurality of attributes can comprise at least one of a luminescent type, a mounting type, or a luminescent feature. The data processing system can detect, responsive to input via a graphical user interface, a layout for installation of the lighting system. The data processing system can select, using a model configured to satisfy a gap constraint, a plurality of light fixtures based on the layout and the plurality of attributes that, when electrically coupled to conform to the layout, satisfy the gap constraint. The data processing system can provide an instruction to cause manufacturing of the selected plurality of light fixtures in accordance with the layout and the plurality of attributes.

A method and apparatus for producing an object (2) comprising providing a digital model (14) of the object (2) that is to be produced; using the digital model, identifying one or more parts (8) of the object (2) that satisfy certain criteria; for each identified part (8), adjusting, in the digital model (14), the thickness of that part (8) to satisfy further criteria, thereby producing an updated model; performing a first production process to produce the part or parts (4, 6) of the object (2) that do not satisfy the criteria, thereby producing an initial object (17); performing an Additive Manufacturing process to add, to the initial object (17), the one or more identified parts (8), thereby producing the object (2). The initial object (17) and identified parts (8) are made of the same material. The first production process is different to the Additive Manufacturing process.
