Move control points to change boundaries and paths.
Control points appear as magenta cubes associated with objects you create using the sketching tools. Control points allow you to change the shape of a building footprint, alter the course of a roadway, or modify the boundary of a pond.
Control points appear at each corner along the perimeter of the building footprint.
Roads / Railways / City Furniture
Objects that use paths display their control points at the ends and corners.
Water Areas / Coverages / Tree Groups
Objects that are defined by boundaries have control points at each corner.
Individual Trees / City Furniture
Individually sketched objects like a single tree or piece of city furniture have a control point at their base.
Result: For buildings, the footprint is changed while the height is maintained. For roads, railways, or paths of city furniture, the path is changed and a new course is displayed. For water areas, tree groups, or coverages, the boundary is adjusted to cover more or less space. For individual trees and pieces of city furniture, the object is moved on the XY plane as if using the Move gizmo.
