The Comparison of the Manual and CAD Systems for Pattern Making, Grading and Marker Making Processes

Abstract

The objective of this research is to conduct a comparison in pattern and marker making between the CAD and manual methods as regards individual course steps and total time values, and to determine the effective of model complexity on these times. For this purpose, four models starting from the simplest to the most complex were designed, and the course steps of the traditional manual method and CAD were first established. Each course step was carried out repeatedly by an expert according to statistical norms. In order to determine in which steps and for which model CAD can be more productive, the data obtained for both methods was compared with respect to the individual time value of each course step and the total time values. Furthermore, the possible causes of the results obtained were discussed and suggestions were put forward.
