How to remove collinear points or vertices from a Line String or Complex Chain
When a Line String or Complex Chain contains mulitple collinear points or vertices (see Image 1) and it is desired to reduce or remove these, is there a method to do this while keeping only the points where the line changes direction?
Before executing, choose a different colour from Element Attributes and enable 'Use Active Attributes' in the Move/Copy Parallel tool settings. This will display the copied element in a different colour and show the difference between new and original.
