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