Hi guys,
I want to combine the imported osm streets and shapefile in CityEngine, but I have encountered two problems. Could you please help me solve this?
First I imported the osm street into CityEngine, after that I tried to delete the streets which can not be aligned to the terrain, but I can not delete them after selecting. The streets are just like the picture below,

The second problem is the shapes which I imported into CityEngine coincide with the imported streets. The picture below shows this problem. What should I do to deal with this problem, is there any function or CGA rule to handle this?

This is the shapefile which I imported into CityEngine.

This picture shows that the shapes coincide with the imported streets.
Thank you for your help!
