Download class-hierarchy.dia Files (Malware-Tested 100% Clean)

CAUTION : We strongly advise against downloading and copying class-hierarchy.dia to your appropriate Windows system directory. Inkscape typically does not release Inkscape DIA files for download because they are bundled together inside of a software installer. The installer's task is to ensure that all correct verifications have been made before installing and placing class-hierarchy.dia and all other DIA files for Inkscape. An incorrectly installed DIA file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
