Cut out a piece of map inside of contour

In a mode Cut out a piece of map inside of contour the marked objects of the map located inside of specified area are deleted.

Before a cutting it is necessary to mark processed objects by means of dialogue Search and mark or with use of modes: Manual marking or Mark for image.

If there is no marked map object, then all objects of a map are marked. In the presence of several maps the dialog for selection of objects on maps opens. Dialog allows to select all objects of one or more maps. Automatically all maps available for editing are selected.

Then it is necessary to choose the closed object on which contour the cutting will be carried out. After a choice of a contour all objects and the parts of the objects located inside of specified area, will be removed.

To cancel deleting of objects it is possible in Undo mode.

For better processing before an execution of a cutting it is recommended to do the control of the objects metrics: in the given mode the objects having self-crossings of contours (loop) and crossing of contours of subobjects are not processed.

At detecting errors of processing the error messages are enter into the log. Upon termination of processing the error messages can be viewed in View errors mode.

For better handling the contours of the objects, going along border of cut out area, it is recommended preliminarily to execute the coordination of metrics of frontier objects.

An example: if contour of border of edge (on which the cutting is carried out) and the rivers (going along border) preliminary are not coordinated, one object (river) can be dissected onto hundreds objects (pieces of the river).

For better handling the contours of objects moving along the cutout area, it is recommended to implement the harmonization of border metrics of objects. Example: if the contour of the boundary edge (for which you are cutting) and the river (runs along the border), not previously agreed upon, then one object (the river) can be dissected into hundreds of objects (pieces of the river).

The note: cutting vector, titles and patterns is not carried out, and their hit into area is defined by the first point of object.
