hi John
the following lines are the ouput of my terminal and at the last i am trying to Draw the detector which is defined in detector construction now as soon as i execute the file examplenN03 the OGLIX window opens and it shows the particle tracks but no detector so at the last of the following lines i was tring to see the detector but nothing is coming in window
