Use Topology subpanel modes to build spatial topology relationships between map objects:

- Copying of object fragment;

- Creating points of objects intersections;

- Snap several vertex;

- Snap two vertex;

- Adjustment of line objects;

- Joining of objects by border of adjacent sheets with the accordance control of semantics of adjustable objects;

- Creating node;

- Joining objects;

- Joining neighboring object points;

- Joining of objects by lists;

- View common vertex of two map objects.
