In V62013 and V62013x, users can save time during material removal simulation by removing intermediate material chunks with a single click rather than having to select each and every bit of the floating material around the machined workpiece to remove. This helps is eliminating redundant collisions reports between cutting tools and the floating material chunks. The 'remove chunks' capability can be activated during simulation, especially following  a new tool change, so that the user can eliminate the possibility  of redundant collisions. ( In V5 user had to manually pick each and every floating bit of material). See video illustration below.
