Problem: Cannot create intersections between multiple graph networks in CityEngine

Description

After importing separate layers into CityEngine, such as shapefiles and file geodatabase feature classes, it is not possible to create intersections by using the Freehand Street operation to connect one layer to another.

Cause

Intersections are not created if the streets reside in two different layers. This is expected behavior.
