BCRD

This program does the same thing as TOPBCRD 10.1.15. The difference is that the input file is a BSEGY, *.seg, file instead of a NEZ survey file. The command line arguments are:

  bcrd infile theta sfact x0 y0 z0
  
 infile  =input file name 
 theta   =angle (deg) from current to new x-axis 
    (+)theta counterclockwise (-)theta clockwise
 sfact   =units scale factor: (old)*(sfact)=(new) 
 x0      =X-offset in new coord. units 
 y0      =Y-offset in new coord. units 
 zo      =Z-offset in new coord. units

NOTE: When using BCRD or TOPBCRD, be aware that rotation and translation at the same time may not be the same as translation first, output a file, then rotation second on the translated file. The result of the translation and rotation operations may be viewed by running the program BCAD 10.1.17 which produces a DXF file from the altered headers.
