Heelo,

This ways to program is crazy,

the simple way is to build 1 mesh of sphere add after you just move the sphere to change the centre to  
[ox[i],oy[0],oz[0]] for each i with movemesh function.

Yes because the mesh Th3 is remove outside of brace

{  
mesh3 Th3 = …  
}  
here Th3 do not exist (like in C++)
