Help needed in using opengl !


I need to developing opengl interface for displaying and, possibly, manipulating (selecting entities, rotating, pan etc.) for a cad geometry. Also, we need to import and display dxf file basically on windows platform.
I know some c++ and vc++ MFC programming but, i’ve never worked on graphics. What are the things that i need to know assuming that I’m starting from scratch.
I need your help urgently as this is a urgent project and I need to access the time required for this.
