Building parameters of point Т3  group is intended for input of distance from an initial point up to created picket, and also of value of an angle. The picket point can be at the left or to the right of basis of building, therefore by means of the dropping-down list it is necessary to set a type of an angle - left or right.  

At filling of "Name of built point"  field the specified information is placed into semantics of created point object.  

Put a tick into an element "Do you want to save line?"  for creation of the linear object connecting an initial point with picket.  

The second group displays coordinates of points, length and a direction angle of base of building. Point Т1  and Point Т2  fields contain coordinates of points of a base line (reference line), and a field Point Т3  - coordinates of picket. Coordinates of picket are calculated automatically at filling fields: Distance to point T3  and Angle  (Building parameters of point Т3  group).  

By means of radio-buttons T1  and Т2  of Point of standing  subgroup it is possible to change a direction of base of building, i.e. to change by places initial and final points of base.  

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, or by means of the button «…» to add an existing user map.  

Object type  group is intended for a choice of a conventional symbol from the classifier of an edited map for created point and linear objects.  

To map  button is intended for creation on an edited map of a picket point and a line connecting an initial point with picket (if the tick is put in element "Do you want to save line?"  in Building parameters of point Т3  group). The button becomes accessible after input of initial data and automatic calculation of coordinates of picket.  

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

For copying into the clipboard the value of an angle it is necessary on any of fields of a component Direction angle  or Angle A to call the contextual menu by the right button of the mouse and to choose a line "Copy angle" . Value of an angle will be copied into the clipboard in a format: degrees minutes seconds, through blanks.  

To insert from the clipboard the value of an angle it is necessary on any of fields of Angle A  component to call the contextual menu by the right button of the mouse and to choose "Paste angle"  line. Value of an angle for an insert from the clipboard is expected in a format: degrees minutes seconds, through blanks if the format is observed, value will be placed into corresponding fields.  

At deleting the value of an angle (the contextual menu by the right button of the mouse, the line "Delete angle" ) the angle with values 0embim120' 0" is placed into fields of angle's values.
