A XCC (YCC, ZCC) is an infinite circular cylinder parallel to the x (y, z) axis. Each XCC (YCC, ZCC) is defined by 3 numbers: A_y, A_z (A_z, A_x for YCC, A_x, A_y for ZCC) (coordinates of the cylinder axis), R (cylinder radius) An XCC (YCC, ZCC) definition, in fixed format, extends always over one single line. Example in default fixed format:*...+....1....+....2....+....3....+....4....+....5....+....6....+....7..XCC 013 -480.0 25.0 300.0* (an infinite cylinder of radius 300 cm, with axis defined by y=-480,* z=25)ZCC 014 0.0 0.0 2.5* (an infinite cylinder of radius 2.5 cm, with axis equal to the z axis)The same example in high-accuracy body fixed format:*...+....1....+....2....+....3....+....4....+....5....+....6....+....7....+.XCC 013 -480.0 25.0 300.0 ZCC 014 0.0 0.0 2.5 The same, in free format: XCC Column -480.0 25.0 300.0 ZCC Tunnel 0.0 0.0 2.5
