plotting – How to show orthogonal views for a 3D plot

Sample object:

g=Graphics3D({Cylinder(),Blue,Cuboid({-2,-3,-1},{2,3,0})},Boxed->False)

enter image description here

There are special commands for this:

Show(g,ViewPoint->#)&/@{Back,Bottom,Front,Top,Left,Right}

enter image description here

The usefulness of all projections (Left different from Right etc.) is more clear on a completely asymmetric case:

m=ConvexHullMesh(RandomReal({-1,1},{30,3}));
Show(m,ViewPoint->#)&/@{Back,Bottom,Front,Top,Left,Right}
