I have never seen this in Scilab 4, 5 or 6. 3D rotations have always 
been prone to some stretching of the axes in order to fill the more as 
possible the axes_bounds whatever are the rotation_angles, isoview and 
cube_scaling values.
Could you provide a sample running on Scilab 5 and preventing this 
stretching?
Thanks.

x  =  [0:0.3:%pi]';
y  =  [0:0.3:2*%pi];

z  =  sin(x)*cos(y);
[xx,yy,zz]  =  genfac3d(x,y,z);
plot3d(xx,yy,zz)

for  iv  =  ["off"  "on"]
     ax.isoview  =  iv;
     for  cs  =  ["off"  "on"]
         ax.cube_scaling  =  cs;
         for  a  =  0:3:720,  ax.rotation_angles(2)  =  a;  sleep(100);  end
     end
end
