This paper describes a concept of a novel webbased CAD software for gear shaper cutters, including its core implementation aspects. Web-based system is proposed as a better alternative to traditional desktop CAD systems based on case study of Dathan Tool & Gauge Co. Ltd. One of the main issues in the development of a web-based CAD system is the need to process and, subsequently, visualise a lot of technical product drawings and sketches. Conventional web-oriented design systems are either integrated with specialised CAD software for processing technical drawings or use dedicated graphics visualisation tools. The proposed web-based CAD software tool for gear shaper cutters relies on technologies supported by regular web browser programs with no need for additional client software and is based on the freely available components and standards.

The transition to a secure low-carbon system is raising a set of uncertainties when planning the path to a reliable decarbonised supply. The electricity sector is committing large investments in the transmission and distribution sector upon 2050 in order to ensure grid resilience. The cost and limited flexibility of traditional approaches to 11 kV network reinforcement threaten to constrain the uptake of low-carbon technologies. This paper investigates the suitability and cost-effectiveness of smart grid techniques along with traditional reinforcements for the 11 kV electricity distribution network, in order to analyse expected investments up to 2050 under different DECC demand scenarios. The evaluation of asset planning is based on an area of study in Milton Keynes (East Midlands, United Kingdom), being composed of six 11 kV primaries. To undertake this, the analysis used a revolutionary new model tool for electricity distribution network planning, called scenario investment model (SIM). Comprehensive comparisons of short- and long-term evolutionary investment planning strategies are presented. The work helps electricity network operators to visualise and design operational planning investments providing bottom-up decision support.
