During toolpath replay, which visual cue indicates a potential gouge? A) Green line B) Yellow line C) Red line D) Blue line Answer: C Explanation: In DELMIA, a red-colored toolpath segment signals that the tool is cutting into material that should have already been removed (over-cut). Question 27. In material removal simulation, the “Remaining Material” is shown in which color by default? A) Blue B) Magenta C) Cyan D) Gray Answer: D Explanation: The default visualization uses gray to represent stock that has not yet been removed.
