SO I am very very new to Arduino, I am Currently trying to build a simple robotic Arm that will consist few servos and an Arduino UNO Board. I have a Problem with choosing and Easy to use CAD software that will help me design my robotic arm and will also allow me to include Servos and let me simulate or least let me see what will happen once I build the Arm 
All your inputs are very welcome.

I like AutoSketch but it most certainly has no support for simulations.
That was Fast Thanks Mate, I'll look in to that.
There is plenty of CAD software available. But, there is a lot that is missing from your description.
"Design the arm". Does this mean design the links to be manufactured, once you know the lengths, thicknesses, etc. Or, does it mean that you are trying to define the lengths and range of angles needed for a robot positioned at point A to be able to reach points B, C, and D.
Completely different software is needed for those two tasks.
Try Solidworks or Autodesk Inventor, they are pretty straightforward, and easy to learn.
