A Question about adjacency matrix

Dear Sir,

I am a teaching assistant in Faculty of Engineering in Mansoura University
Egypt.

I am a Mathematica 7  user from about 4 months .

I have a problem about the construction of adjacency matrix .

My problem :

I construct a graph by "Graphics3D" function & I need to get the adjacency
matrix to this graph .

I tried  this :

Needs["Combinatorica`"]
ToAdjacencyMatrix[graph]

but it doesn't give me the matrix.

What should I do?

I need your help.

Thanks

Marwa Ali
