I have a large dataset of line segments, which are both curved and straight. The problem is, some of the lines have hundreds (possibly thousands) of vertices. I would like to remove enough vertices without affecting the shape of the line. What is the best way to do this?

The Generalizer will remove colinear points from lines - you'll probably want one of the generalizing algorithms if the aim is just to reduce the density of points

Thanks, I tried this and it worked really well. The 'Thin No Point' algorithm did not change the shape of line with a low generalizing tolerance!
