The cut tubes constructor has the form:

TGeoCtub(Double_t rmin,Double_t rmax,Double_t dz,
Double_t phi1,Double_t phi2,
Double_t nxlow,Double_t nylow,Double_t nzlow, Double_t nxhi,
Double_t nyhi,Double_t nzhi);

A cut tube is a tube segment cut with two planes. The centers of the 2 sections are positioned at dZ. Each cut plane is therefore defined by a point (0,0,dZ) and its normal unit vector pointing outside the shape:

Nlow=(Nx,Ny,Nz<0), ‘Nhigh=(Nx’,Ny',Nz'>0)`.
