Description
This paper presents some considerations regarding the extracting of geometrical data
from CATIA models with the aim of using this data to program computer numerical
control machine tools that do not have postprocessors integrated in the CATIA
environment. This data usually represents holes and plane contours defined by their
characteristic points. The paper defines how the information is organized in files and how
these files can be used by postprocessor applications. A postprocessor that uses such
information is also presented
