A curve extracting apparatus for extracting curves such as closed loops, open loops and hole groups from drawing data prepared with a CAD system, and an NC programming system for forming NC programs by directly utilizing curves which are extracted by the curve extracting apparatus. With such apparatus and system, it is unnecessary to perform complicated operations such as a drawing data reading operation, a coordinate calculating operation and a numerical data inputting operation and the occurrence of errors can be eliminated, and the drawing data prepared with a CAD system can be directly utilized to form an NC program.
