Orthographic Images

I am using Maya to create my base meshes and realize the importance of
Orthographic Images.
I have searched all over the internet for them but can’t seem to find any good one’s.
Do most people draw their own?
I can’t draw at all so i am hoping that someone can lead me in the right direction.

Maybe a program that makes Orthographic drawing easier?
Thanks for any reply’s or suggestions.
