Horizontal, rotated or complex rectangle

Top

For creation of a horizontal rectangle it is necessary by left mouse button click to indicate on a map positions of its two vertexes which form a diagonal.

For creation of a rotated rectangle it is necessary by left mouse button click to indicate on a map positions of its three vertexes (side and diagonal). The first and the second vertex can be obtained by copying of points of already existing objects (Auxiliary modes T and I).

For creation of a composite rectangle it is necessary by series left mouse button click to indicate a position of its one edges (it is recommended to start creation from the most extended edge), and then by left mouse button click to indicate a position of its remaining vertexes. Thus the right angles form automatically, the points - vertexes of a rectangle are entered through one. The first and the second point can be obtained by copying of points of already existing objects (Auxiliary modes T and I).  Object saving is made at the moment of completion of executed operation.
