Line 20: === Neutral file exchange === Neutral file exchange uses an intermediary neutral format to translate data between CAD systems. This method starts from a pre-processor embedded in the original CAD system, which generates the neutral file from the originating CAD format. The target CAD system post-processes the neutral file and converts it into the target native format.<ref>{{cite journal \|last=Choi \|first=G.-H. \|last2=Mun \|first2=D.-H. \|last3=Han \|first3=S.-H. \|date=1 January 2002 \|title=Exchange of CAD Part Models Based on the Macro-Parametric Approach \|journal=International Journal of CAD/CAM \|volume=2 \|issue=1 \|pages=13-21 \|url=https://pdfs.semanticscholar.org/13ca/477671832ff1d157cf17849876624da346d5.pdf}}</ref> Some neutral formats are defined by standards organisations such as [[IGES]] and [[ISO 10303\|STEP]] while others are proprietary but still widely used and are regarded as quasi industry standards.<ref name=":15" /> ==== Neutral formats ====
