Rendering 3D Over 2D

I'm trying to render 3D over 2D in Monogame, but can't figure out why it won't work! Here's the drawing callback: /// <summary> /// This is called when the game should draw itself. /// </summary> /// <param name="gameTime">Provides a snapshot of timing values.</param> protected override void Draw(GameTime gameTime) { Resolution.BeginDraw(); spriteBatch.Begin(SpriteSortMode.Deferred, BlendState.AlphaBlend, null, DepthStencilState.Default, RasterizerState.CullCounterClockwise, null, Resolution.getTransformationMatrix()); m_ScrManager.Draw(); spriteBatch.End(); //Reset device to defaults before rendering... GraphicsDevice.BlendState = BlendState.Opaque; GraphicsDevice.DepthStencilState = DepthStencilState.Default; GraphicsDevice.RasterizerState = RasterizerState.CullCounterClockwise; GraphicsDevice.SamplerStates[0] = SamplerState.LinearWrap; GraphicsDevice.Viewport = new Viewport(0, 0, GlobalSettings.Default.ScreenWidth, GlobalSettings.Default.ScreenHeight); m_ScrManager.Draw3D(); HitVM.Step(); base.Draw(gameTime); } } Here is Resolution.cs: ////////////////////////////////////////////////////////////////////////// ////License: The MIT License (MIT) ////Copyright (c) 2010 David Amador (http://www.david-amador.com) //// ////Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: //// ////The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software. //// ////THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

Why? :\
