Arrangement of pickets along object (data from database) dialog

This mode is intended for arrangement of pickets along object according to information from the table of a data base.  

By means of this mode it is possible to create picket points both on object, and on a straight line which is perpendicular to a current piece of the metrics of object. As data are taken from the table, the user does not operate their quantity.  

The number of created pickets is defined by values which are taken from a database. That is, pickets are placed not proportionally to one length, and according to those values which are stored in a data base (DB). It is necessary for user to specify a table name of a DB in an element «Data Base». Then to specify a field of a database from which numerical values of lengths of pieces between created pickets will be got. After that, values of lengths of pieces can be seen in an element «L1i». If in a DB the length of pieces is specified between adjacent pickets, it is necessary to put a tick in an element «To summarize lengths of pieces at drawing». In the event that lengths of pieces for each created picket are specified from a start point it is necessary to take off a tick.  

At arrangement of pickets along object according to information from the table of a database the concept of a start point is used.  

The starting point is specified by the user. That is, arrangement of pickets is made not on all object, and by its part. At change of a direction (T1-> T2) the direction of drawing of pickets varies, but not a start point.  

If it is necessary to specify accommodation of pickets concerning initial object (to the right, at the left) use the corresponding elements from group "side".  

If it is necessary to create pickets directly on initial object specify number of pieces on a perpendicular equal to zero. Otherwise points will be created on the object, and a conditional line which is perpendicular to a current piece of the metrics of initial object. The distance through which the pickets will be created is set in an element «L2». The number of points created on a perpendicular is specified in an element «Number of pieces».  

Current map  group is intended for a choice of an electronic map on which the objects will be created. The edited map can be chosen from the list of the open maps.  

Object type  group is intended for a choice of a sample of created point object from the classifier of an edited map.  

Back  button is intended for a cancelling of operation on creation of objects on an edited map.
