Description of dialogue Calculation of coordinates (method of stvors)

Building parameters of point Т3  group is intended for input of distance from a point of basis up to a created picket point. What distance to use, from point Т1  or points Т2  of basis, specify by means of the drop-down list.  

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 point of basis with picket point.  

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 Point Т3  field - coordinates of picket. Coordinates of picket are calculated automatically at filling fields: Distance from point  (Building parameters of point Т3  group).  

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 the lines connecting points of basis with a picket point (if the tick in an element is put "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 of value of an angle it is necessary on any of fields of corresponding components: Direction angle  to cause 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 minute second, through blanks.
