I have been watching a tutorial using the pen tool to create an illustration. What I have for the most part done is create paths that overlap and then using the shape builder tool get rid of the overlapping path. Sometimes I find using the shapebuilder tool creates a lot of extra points.
The method in the tutorial is to create overlapping paths and then select all, then go to the pathfinder and select "outline" then in the tutorial they use the lasso tool to select overlapping paths and delete them.
With the pathfinder outline however it breaks up the paths that intersect. So I am just wondering why this method would be used in the tutorial?
