CATIA V5 Tutorial: How to Enable Light Mode in CATIA V5?

Light mode is the term given to load just the 3D data and not the V4 Drawing data. By default when you import CATIA V4 model into CATIA V5, V4 drawing file is also opened along with 3D model file. This can be disabled so that only 3D model file will open to reduce the loading time. This is useful especially when you just want 3D data for reference and not the V4 Drawing Data while designing surrounding parts.
