# 3.9.9: Remove Duplicate Lines

When you have a list of lines that you suspect of containing duplicate lines then send it through this component and out comes a purified list of ones of a kind. The input-value for **“LDist”** determines the limit distance between nodes to be considered as identical. Lines of length less than **“LDist”** will be discarded. Lines that overlap only partly are not detected.
