If your computer is set to display LDraw files from the web, filling out this form should result in an LDraw file being displayed on your screen, in white, green and trans-red. White areas are where the two files match exactly. Trans-Red areas are deleted sections. Green areas are are new sections. And areas that are green overlayed with trans-red are parts that are changed from the old file to the new file -- possibly they were coded a different way, or adjusted slightly.
