Set of objects

By operation with a digital map it is necessary to select a collection of logically linked objects  for solution of the applied tasks.

The set of objects is a collection of logically linked objects, inherings to one map sheet.

The objects in a set can be equivalent or one object can be main, and remaining - subordinate.

Use a semantic record to save a sign of belonging of object to a set of objects.      

The equivalent objects unite by using of semantic characteristic with code 32803.

The main object in a set has the characteristic with the code 32801, subordinate - 32802.

Value of the characteristics is unique number of a set in a sheet.

At execution of object editings (moving, deleting etc.) its belonging to a set of objects can be taken into account. For this purpose you must include Editing object group function in editor options (Options menu).

At editing a set of objects wholly it is selected according to colour and line thickness installed in Сolors item of  Options menu.

The special functions of a Map editor are applied for creation of objects set.
