I need to generalize a road network to be an exact angle to each other, we are talking about parallel streets like New York.

The thing is that when you generalize, you do it per feature.

I am trying dissolve and unsplit, but then it goes past the parallel streets and the generalization destroys curved streets.

I do not want to do it manually, it is a line feature. think of one road that is straight, but the data is not. all line comes as splited in intersections. when generalizing, the output is not generalizing the hole straight road, so the road will still be full of vertexes. but when I dissolve the generalization gets better, but then if one street is changing direction at the end of the block, the topology disappears . look at the link :)https://docs.google.com/file/d/0B8sJ0k30rFr2SkNWVllWMDMxY1k/edit?usp=sharing https://docs.google.com/file/d/0B8sJ0k30rFr2TTNuLWpaNlJFY1k/edit?usp=sharing

so on the brown lines you can see that within the red area the block is basically rectangular, but the end curves, so when generalising, the curve gets vertexes removed, and now it is really not straight –
