The edges of the raft foundations are surrounded by strips or shearwalls. However, in some cases, some edges of the raft foundations are not covered with these elements, they are empty. However, in order to define raft foundation, the boundaries of raft foundation must be defined in some way.
The program has developed raft edges for this job. Raft edges are objects that are used to determine the raft foundation boundary. All boundaries of raft foundations or borders not defined by strips and shearwalls are defined by the raft edge.
