drawing hud problem | GameDev.net

i have pasted the code at the bottom it is executed in the same order as pasted below well my problem is my orthographic plane stays at the same position i can only draw in 2d on my screen when i don t call the Render3D() function is there something i am doing wrong or whats on?
