Dear Mike and John,

Thanks for your reply and advice. I did it in the following way and it works.

First step: I construct a layer (Box_1, PhyBox_1) which contains Lead. It is labeled by the blue color (Fig.1). Box1 has the following parameters:

X1=length

Y1=width

Z1=thickness

Second step: I construct another layer (Box_2, PhyBox_2) with the following dimensions:

X2=X1

Y2=Y1/3 // I need only 3 holes in y direction

Z2=Z1

Box_2 is labeled by Yellow color (yellow lines shown in Fig.1), it contains Lead and it is a daughter volume of Box_1.

Third steep: I construct a cylinder (Tube, PhyTube1) with an inner radius (Rin=0), a given outer radius Rout (Rout is now the radius of the hole) and a height Z=Z1=Z2. The cylinder contains vacuum. Its mother volume is the Box_2. Holes are depicted with white color (Fig.1).

For instance, to get a layer containing 3x3 holes, The Tube1 is repeated three times inside the Box_2 along the X axes (with a given offset) and then the Box_2 is itself repeated along the Y axes. I hope I did not make a mistake.

Cheers

Brahim
