“…Furthermore, the details of the stages involved in the production of the 3D CAD Fire Size for the four components of the product are presented in Figures 12 -15. It is, therefore, possible to use the results from these stages as a reference for CAD engineers in the ceramic industry in implementing RE in teapot type ceramic products as also successfully applied by previous researchers in the insole, body implant, part machine, and other products in different industries (Andrei et al, 2015;Anggoro et al, 2017Anggoro et al, , 2018Anggoro, Yuniarto et al, 2019;Babu & Thumbanga, 2011;Feng et al, 2014;Fergiawan et al, 2019;Huson & Hoskins, 2014;Hussain et al, 2008;López et al, 2014;Wang, 2008). The scanning output in .stl format was, however, generally converted by line processing to the surface and solid modeling in the CAD software used by the CAD researchers or engineers in the manufacturing industry (Anggoro et al, 2017;Babu & Thumbanga, 2011;Huson & Hoskins, 2014;Hussain et al, 2008;López et al, 2014;Sokovic & Kopac, 2005;Wang, 2008).…”
