Snapping lines to points

Question

i have to snap the point the Layer containing point 'A' the layer of point 'B' , but i have a third layer of vector which is a line layer containing 'line 1', so each vector has a point of layer 'A' as origin of vector, so i like to make snapping in the layers of vectors to point 'B' layer but without changing the angle of the line , like a shift of the whole line not just one point, so the result of the snapping of 'line 1' will be 'line 2'.

i'm working Arcgis engine 10 .NET, i'm open for solutions working just arcgis 10 so i can make the same geoprocessing in arcgis engine.

any suggestion is welcome.

Answer 1

i have made an ArcPy code to virtualy snap the lines , so the script calculats the bearing of the lines , snap the origin of the vector, then build new lines from new snapped points using the bearing.

but i have noticed a weird error using the function BearingDistanceToLine_management in arcpy it add an angle of to the bearings , without understanding the cause of the error i have eliminated the difference by 180 - 57.935

import arcpy

#arcpy.AddField_management("directions" , "bearing" , "FLOAT" )

arcpy.CalculateField_management("directions" , "bearing" , "180 - 57.935 + math.atan2(( !Shape.firstpoint.X! - !Shape.lastpoint.X! ),( !Shape.firstpoint.Y! - !Shape.lastpoint.Y! ) ) * (180 / math.pi)" , "PYTHON_9.3")

arcpy.Snap_edit("borne" ,  [["D_GPS", "VERTEX", "5"]] )

arcpy.MakeFeatureLayer_management("borne" , "borne_join")
#arcpy.AddField_management("borne_join" , "X" , "DOUBLE" )
#arcpy.AddField_management("borne_join" , "Y" , "DOUBLE" )

arcpy.CalculateField_management("borne_join" , "X" , "!Shape.lastpoint.X!" , "PYTHON_9.3")
arcpy.CalculateField_management("borne_join" , "Y" , "!Shape.lastpoint.Y!" , "PYTHON_9.3")

#arcpy.AddField_management("borne_join" , "distance" , "SHORT" )
arcpy.CalculateField_management("borne_join" , "distance" , "5" , "PYTHON_9.3")

arcpy.MakeFeatureLayer_management("directions" , "dir_join")

arcpy.AddJoin_management("dir_join" , "borne_id" , "borne_join" , "id" )

arcpy.BearingDistanceToLine_management("dir_join" , "new_dir" , "sde.sde.borne.X" , "sde.sde.borne.Y" , "sde.sde.borne.distance" , "METERS" , "sde.sde.directions.bearing" , "DEGREES"  , "GEODESIC" )

arcpy.Delete_management("borne_join")
arcpy.Delete_management("dir_join")
