I would like to create a unique object p (patch) so as to preserve some features like faces' color and surface , upon wich i can plot another figures , so as to preserve the previous figures , modifyng only the S.Vertices.

surf=gca;
xlim(surf,[-10 10]);
xlabel('x');
zlim(surf,[-10 10]);
zlabel('z');
ylim(surf,[-10 9]);
ylabel('y');
daspect([1 1 1]);
%first figure
S.Vertices=[1,1,1;4,1,1;4,4,1;1,4,1; 1,1,4;4,1,4;4,4,4;1,4,4];
S.faces=[1,2,3,4;1,2,6,5;3,2,6,7;4,3,7,8;4,1,5,8;5,6,7,8];
p=patch(gca,S);
p.FaceVertexCData=[1 0 0; 0 1 0 ; 0 0 1 ; 0 1 1 ; 1 0 1 ; 1 1 0 ];
p.FaceColor="flat";
%simple object rotation
theta=pi/2;
mry=[ cos(theta)   0   sin(theta) ;
         0        1      0     ;
     -sin(theta)    0  cos(theta)];
 S.Vertices=mry*S.Vertices';
 S.Vertices=S.Vertices';
 % second figure
p=patch(S);
p.FaceVertexCData=[1 0 0; 0 1 0 ; 0 0 1 ; 0 1 1 ; 1 0 1 ; 1 1 0 ];
p.FaceColor="flat";
