```I'm wondering if it's possible to draw (convex) polytopes defined by
systems of linear inequalities. For example the system:

x + 2y + z <= 3
2x - y >= 0
-x + 2y + z >= 0
y + z >= 0
2x + 3y + 3z >= 1

Can I get Mathematica to draw the polytope defined on R^3 by this system?

I'm able to solve this system with
InequalitySolve[{x+2y+2z<=3,2x-y>=0,-x+2y+z>=0,y+z>=0,2x+3y+3z>=1},{x,y,z}]
but the data is hard to interpret this way.

btw; the same problem, but a little more intuitive, would be to draw a
cube with the system defined below:

{x >= -1, x <= 1, y >= -1, y <= 1, z >= -1, z <= 1}

Any hints are appreciated,
