How to draw foundation in relation to existing grade line

[MCORTEZ]

Hi all,
I would like to know if there is anyone who is willing to show me how to accurately draw a stepped foundation in relation to existing grade. I have drawn the attached elevation, but the steps are not accurate as i tried to make them all cemeterial to one another.

Any input on the order of steps to accurately draw a stepped footing would be appreciated.

Thank you

Something like the attached... just an arbitrary grade shown to give you some practice.

Rather than think climate change and the corona virus as science, think of it as the wrath of God. Feel any better?
