Dear David,
Thank you so much for your help. I followed your instructions and got some
success in moving ahead. However, I am NOT able to get the 3D position of
the markers. I get the values +00 or some random values when I apply the
command "Command("3D:011")" . I was expecting it to be x,y,z coordinate
value with the error value. Following is the current status of the code and
the results. Our team and I really appreciate your kind help.
