Combined mode of line creation

The mode is intended for creation of linear and polygon objects and it is a combination of modes:

- creation of free contour (1);

- smoothing spline (spline1) (2);

- describing spline(spline2) (3);

- arch of a circle by three points (4);

- double line (an axis by a left edge) (5).

After start of a mode and a choice from the classifier of type of created object the mode of creation «Free contour» "by default" is used. During the object creation the change of creation mode can be executed by pressing keys of the keyboard 1-5 or the corresponding button of an auxiliary panel of tools which is created after start of a mode and disappears after its deactivation.

At change of creation mode the fixation of the earlier created part of object is made. I.e. the created object can consist of sequence of the parts created in the different ways.

Except for the basic modes of creation the additional combination of a creation mode «Free contour » with additional modes is possible:

- creating a horizontal line (H);

- creating a vertical line (V);

- creating a right angle (R).

During work of this mode the auxiliary modes of capture of points (K), lines (J), and also a copy of a point (I and T) and a part (P) of existing map object are accessible.
